Earthquake Essay for Students and Children

500+ Words Essay on Earthquake

Simply speaking, Earthquake means the shaking of the Earth’s surface. It is a sudden trembling of the surface of the Earth. Earthquakes certainly are a terrible natural disaster. Furthermore, Earthquakes can cause huge damage to life and property. Some Earthquakes are weak in nature and probably go unnoticed. In contrast, some Earthquakes are major and violent. The major Earthquakes are almost always devastating in nature. Most noteworthy, the occurrence of an Earthquake is quite unpredictable. This is what makes them so dangerous.

Types of Earthquake

Tectonic Earthquake: The Earth’s crust comprises of the slab of rocks of uneven shapes. These slab of rocks are tectonic plates. Furthermore, there is energy stored here. This energy causes tectonic plates to push away from each other or towards each other. As time passes, the energy and movement build up pressure between two plates.

Therefore, this enormous pressure causes the fault line to form. Also, the center point of this disturbance is the focus of the Earthquake. Consequently, waves of energy travel from focus to the surface. This results in shaking of the surface.

Volcanic Earthquake: This Earthquake is related to volcanic activity. Above all, the magnitude of such Earthquakes is weak. These Earthquakes are of two types. The first type is Volcano-tectonic earthquake. Here tremors occur due to injection or withdrawal of Magma. In contrast, the second type is Long-period earthquake. Here Earthquake occurs due to the pressure changes among the Earth’s layers.

Collapse Earthquake: These Earthquakes occur in the caverns and mines. Furthermore, these Earthquakes are of weak magnitude. Undergrounds blasts are probably the cause of collapsing of mines. Above all, this collapsing of mines causes seismic waves. Consequently, these seismic waves cause an Earthquake.

Explosive Earthquake: These Earthquakes almost always occur due to the testing of nuclear weapons. When a nuclear weapon detonates, a big blast occurs. This results in the release of a huge amount of energy. This probably results in Earthquakes.

Effects of Earthquakes

First of all, the shaking of the ground is the most notable effect of the Earthquake. Furthermore, ground rupture also occurs along with shaking. This results in severe damage to infrastructure facilities. The severity of the Earthquake depends upon the magnitude and distance from the epicenter. Also, the local geographical conditions play a role in determining the severity. Ground rupture refers to the visible breaking of the Earth’s surface.

Another significant effect of Earthquake is landslides. Landslides occur due to slope instability. This slope instability happens because of Earthquake.

Earthquakes can cause soil liquefaction. This happens when water-saturated granular material loses its strength. Therefore, it transforms from solid to a liquid. Consequently, rigid structures sink into the liquefied deposits.

Earthquakes can result in fires. This happens because Earthquake damages the electric power and gas lines. Above all, it becomes extremely difficult to stop a fire once it begins.

Earthquakes can also create the infamous Tsunamis. Tsunamis are long-wavelength sea waves. These sea waves are caused by the sudden or abrupt movement of large volumes of water. This is because of an Earthquake in the ocean. Above all, Tsunamis can travel at a speed of 600-800 kilometers per hour. These tsunamis can cause massive destruction when they hit the sea coast.

In conclusion, an Earthquake is a great and terrifying phenomenon of Earth. It shows the frailty of humans against nature. It is a tremendous occurrence that certainly shocks everyone. Above all, Earthquake lasts only for a few seconds but can cause unimaginable damage.

FAQs on Earthquake

Q1 Why does an explosive Earthquake occurs?

A1 An explosive Earthquake occurs due to the testing of nuclear weapons.

Q2 Why do landslides occur because of Earthquake?

A2 Landslides happen due to slope instability. Most noteworthy, this slope instability is caused by an Earthquake.

Over the centuries, earthquakes have been responsible for millions of deaths and an incalculable amount of damage to property. Depending on their intensity, earthquakes (specifically, the degree to which they cause the ground’s surface to shake) can topple buildings and bridges , rupture gas pipelines and other infrastructure, and trigger landslides , tsunamis , and volcanoes .  These phenomena are primarily responsible for deaths and injuries. Very great earthquakes occur on average about once per year.

Earthquake waves, more commonly known as seismic waves , are vibrations generated by an earthquake and propagated within Earth or along its surface. There are four principal types of elastic waves: two, primary and secondary waves, travel within Earth, whereas the other two, Rayleigh and Love waves, called surface waves, travel along its surface. In addition, seismic waves can be produced artificially by explosions.

Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs . Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10. Richter’s scale was originally for measuring the magnitude of earthquakes from magnitudes 3 to 7, limiting its usefulness. Today the moment magnitude scale, a closer measure of an earthquake’s total energy release, is preferred.

Earthquakes can occur anywhere, but they occur mainly along fault lines (planar or curved fractures in the rocks of Earth’s crust ), where compressional or tensional forces move rocks on opposite sides of a fracture. Faults extend from a few centimetres to many hundreds of kilometres. In addition, most of the world’s earthquakes occur within the Ring of Fire , a long horseshoe-shaped belt of earthquake epicentres , volcanoes , and tectonic plate boundaries fringing the Pacific basin .

Recent News

earthquake , any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” Earthquakes occur most often along geologic faults , narrow zones where rock masses move in relation to one another. The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth’s crust. ( See the table of major earthquakes.)

Little was understood about earthquakes until the emergence of seismology at the beginning of the 20th century. Seismology , which involves the scientific study of all aspects of earthquakes, has yielded answers to such long-standing questions as why and how earthquakes occur.

About 50,000 earthquakes large enough to be noticed without the aid of instruments occur annually over the entire Earth. Of these, approximately 100 are of sufficient size to produce substantial damage if their centres are near areas of habitation. Very great earthquakes occur on average about once per year. Over the centuries they have been responsible for millions of deaths and an incalculable amount of damage to property.

The nature of earthquakes

Causes of earthquakes.

Earth’s major earthquakes occur mainly in belts coinciding with the margins of tectonic plates. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. The most important earthquake belt is the Circum-Pacific Belt , which affects many populated coastal regions around the Pacific Ocean —for example, those of New Zealand , New Guinea , Japan , the Aleutian Islands , Alaska , and the western coasts of North and South America . It is estimated that 80 percent of the energy presently released in earthquakes comes from those whose epicentres are in this belt. The seismic activity is by no means uniform throughout the belt, and there are a number of branches at various points. Because at many places the Circum-Pacific Belt is associated with volcanic activity , it has been popularly dubbed the “Pacific Ring of Fire .”

A second belt, known as the Alpide Belt , passes through the Mediterranean region eastward through Asia and joins the Circum-Pacific Belt in the East Indies . The energy released in earthquakes from this belt is about 15 percent of the world total. There also are striking connected belts of seismic activity, mainly along oceanic ridges —including those in the Arctic Ocean , the Atlantic Ocean , and the western Indian Ocean —and along the rift valleys of East Africa . This global seismicity distribution is best understood in terms of its plate tectonic setting .

Natural forces

Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth . The energy can be released by elastic strain , gravity, chemical reactions, or even the motion of massive bodies. Of all these the release of elastic strain is the most important cause, because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances. Earthquakes associated with this type of energy release are called tectonic earthquakes.

Earthquake Essay

Essay on Earthquake - An earthquake is a natural disaster that occurs when two tectonic plates collide. The force of the collision creates seismic waves that travel through the earth's crust, causing the ground to shake and buildings to collapse. Here are some sample essays on earthquakes.

• 100 Words Essay on Earthquake

Earthquakes can happen anywhere in the world, and although their occurrence is not predictable, there are some things you can do to make yourself more prepared in case one does strike. This includes having an earthquake kit ready to go, knowing how to drop, cover and hold on, and staying informed about any potential risks in your area. Make sure you have an emergency kit stocked with food, water, and other supplies, and know what to do when an earthquake hits. If you're not sure what to do, it's best to stay away from windows and other objects that could fall on you, and head to a safe place.

200 Words Essay on Earthquake

500 words essay on earthquake.

Earthquakes are a natural disaster that come with a lot of dangers. The shaking and movement of the earth can cause buildings to fall down, trapping people inside. The shaking caused by such a sudden change is usually very minor, but large earthquakes sometimes cause very large shaking of the land. The shaking waves spread from the spot at which rock begins breaking for the first time; this spot is called the center, or hypocenter, of an earthquake.

If you're inside when an earthquake starts, drop to the ground and cover your head. The earthquake's magnitude is related to the amount of earthquake energy released in a seismic event.

Different Types of Earthquakes

There are three types of earthquakes:

Shallow | A shallow earthquake is when the earthquake's focus is close to the surface of the Earth. These earthquakes are usually less powerful than the other two types, but can still cause a lot of damage.

Intermediate | Intermediate earthquakes have a focus that's located between the surface and the Earth's mantle, and are usually more powerful than shallow earthquakes.

Deep | Deep earthquakes have a focus that's located in the mantle, which is the layer of the Earth below the crust. They're the most powerful type of earthquake, and can even cause damage on the surface.

An earthquake can cause damage to buildings and bridges; interrupt gas, electrical, and telephone services; and occasionally trigger landslides, avalanches, flash flooding, wildfires, and massive, destructive waves of water over oceans (tsunamis).

The Dangers Associated With Earthquakes

The shaking of the ground can cause objects to fall off shelves and injure people. If you're outside when an earthquake starts, move away from tall buildings, streetlights and power lines.

An earthquake can also cause a tsunami, or a large wave, to form and crash onto the shore. Tsunamis can be very dangerous and can reach heights of over 100 feet.

How to Prepare for an Earthquake

When an earthquake is imminent, your first step should be to find a safe spot. The most ideal spots are under sturdy furniture or inside door frames. It is best to stay away from windows and anything that can fall over.

Once you've found the safest place, it's time to prepare for the shaking. Grab some blankets, pillows and helmets if possible – all of which can provide extra cushioning against falling objects.

Additionally, you should always keep an eye out for debris that could cause injuries, such as broken glass and sharp objects.

Finally, stay calm until the shaking stops, and monitor local news reports for additional information on how best to handle the situation.

What to do During an Earthquake

The moment an earthquake hits, it is important to stay as calm and collected as possible. Safety is the first priority so you must stay away from windows and furniture that can fall on you, and protect your head with your arms if needed.

If an earthquake occurs while you are indoors, stay away from anything that could fall or break such as windows, mirrors, or furniture. Do not run outdoors as shaking can cause glass and other materials to fall from the building structure. Instead, seek shelter under sturdy tables or desks. If there is no furniture available, move to a corner of the room and crouch down protectively with your arms over your head and neck.

It's also important to take note of any gas lines that could be affected during an earthquake and shut them off if necessary in order to prevent fires from breaking out due to exposed pipes.

After the Earthquake: Recovery and Assistance

When the shaking stops, there will be a period of recovery.

Don't enter any building if it has visible damage due to the earthquake - it's better to be safe than sorry.

You should contact local aid organisations like the Red Cross for additional help with sheltering, water, food and other essentials.

Stay in touch with local officials about any services provided for those affected by the earthquake.

Make sure you also have a plan for what to do if you're stuck in an earthquake, and know how to get in touch with loved ones in case of an emergency.

By being prepared and knowing what to do, you can help ensure that you and your loved ones are safe in the event of an earthquake.

Earthquake Essay | Essay on Earthquake for Students and Children in English

February 13, 2024 by Prasanna

Earthquake Essay: Earthquake Essay is an important topic for students to learn about. It educates the students about what an earthquake is and its repercussions. From a geological perspective, earthquakes (Magnitude 2 and smaller) occur several hundred times a day worldwide. These earthquakes occur in very remote places and its aftereffects are nearly imperceptible. Earthquakes that are larger and more destructive (Magnitude 8 and bigger) occur with lesser frequency; typically once or twice per year.

Usually, some places are more prone to earthquakes than others. These places are often located on the intersection between tectonic plates – gigantic plates that glide over the earth’s mantle. When two of these plates grind against each other, earthquakes occur. Depending on the location of the earthquake, it can cause a lot of damage, either through tsunamis, landslides, avalanches, mudslides, or ground displacement. These can cause serious damages to life and property; it can even cripple an entire economy if the magnitude is high enough. Read on to explore more about earthquakes.

Most of us are familiar with the concept of earthquakes and the dangers they pose to us. However, not everyone knows the exact definition nor its probable causes.

What is an Earthquake?

An Earthquake is defined as a phenomenon where tectonic plates slip past one another, creating seismic waves that travel through the earth’s rocks. Depending on the intensity of the earthquakes, the effects can vary from minor structural damages to buildings to complete collapse, resulting in loss of life and property. Sometimes, when an earthquake originates from the middle of the ocean, it can cause extremely large and destructive waves called tsunamis. However, an earthquake does not directly pose danger to a person; in other words, people cannot be shaken to death by an earthquake.

Understanding the Cause of Earthquakes

Now that we know what is an earthquake, we shall explore how it is caused. The earth is made up of four layers – the inner core, outer core, mantle, and crust. The mantle and the crust essentially behave as a very thin layer of shell on our planet’s surface. However, this shell is not composed of one single piece; there are several pieces that exist under the earth, each slowly sliding past one another. These pieces are called the tectonic plates. There are in fact seven tectonic plates that are found under the earth’s crust:

• African plate
• Antarctic plate
• Eurasian plate
• Indo-Australian plate
• North American plate
• Pacific plate
• South American plate

Moreover, these plates are never static, they always keep moving. Over the earth’s history, tectonic plates have merged with other plates to form even larger plates. Other tectonic plates have drifted into smaller plates and some have been even pushed under other plates (subduction). This is one of the biggest reasons why we had supercontinents in the past, and their eventual breakup into the seven continents that we know today.

When two or more tectonic plates meet, the area usually becomes a hotspot for earthquakes. The actual event is caused when these plates start slipping past one another, creating energy in the form of seismic waves. Depending on the location and magnitude, these seismic waves have the potential to absolutely decimate buildings and natural ecosystems. The area where these earthquakes are known to occur is called the geologic faults.

Where do Earthquakes Occur?

Earthquakes can occur anywhere on earth, however, it occurs in more frequency where two tectonic plates meet, especially along the fault lines. The length of fault lines varies between a few meters to hundreds of kilometres. Most of the world’s earthquakes occur in a place called the Ring of Fire, in the Pacific Ocean. The Belt traces boundaries between many tectonic plates, as a result, there is a lot of movement. This consequently makes it geologically active and is considered a very “violent” place from a seismological perspective. Moreover, there are many underwater active volcanoes that line these boundaries, hence the name: Ring of Fire.

How is Earthquake Measured

Earthquakes are measured using a unit called Magnitude. The instrument that measures these units is called seismographs. However, scientists often prefer to use the Moment Magnitude Scale over the magnitude scale is often

Effects of Earthquakes

As stated before, earthquakes do not directly cause harm to humans. However, earthquakes can cause substantial damages to property. One of the most prominent dangers is ground displacement. Any buildings along the fault can collapse, thereby causing injury or death to humans. The effect of ground shaking as a result of seismic waves can also impact the structural integrity of buildings. Roads and bridges may not be traversable due to the damage caused.

Earthquakes also cause an event called liquefaction. This occurs when sand or soil becomes very soft when it gets mixed with groundwater. When liquefaction occurs under a building, it can cause it to tip over, sink several feet, thereby rendering the building a hazard.

Earthquakes can also cause flooding. When earthquakes rupture damns or embankments along a river, water would then flood the area, damaging property and drowning people. When earthquakes occur under the ocean, huge waves called Tsunamis can occur. These waves are extremely destructive and can destroy anything in its wake. Interestingly, when earthquakes occur near lakes, they can cause an event similar to a tsunami, but smaller in scale – it is called Seiches. They are usually only a few feet high, but they are powerful enough to flood property and cause damage.

Can we Predict Earthquakes?

Earthquakes can never be predicted with current technology. However, we can calculate the probability of an earthquake occurring in specific areas (geologically active areas).

FAQ’s on Essay on Earthquakes

Question 1. What causes an earthquake essay?

Answer: Earthquakes are caused when two or more tectonic plates meet.

Question 2. What is an earthquake?

Answer: An earthquake can be defined as the “shaking” of the earth’s surface as a result of a sudden release of energy from the lithosphere.

The Lowdown on Earthquakes: A Tectonic Tango

Have you ever wondered why the Earth takes a little shimmy now and then? It all boils down to a fiery temper tantrum deep below the surface. The Earth’s crust is fractured into giant slabs called tectonic plates, constantly jostling for position like tectonic bumper cars. When these plates grind against each other, snag, or slam into one another, the sudden release of energy sends shockwaves rippling through the Earth-that’s your basic earthquake recipe.

Think of it like a giant trampoline. When you jump on one side, the other side bounces up, right? Earthquakes are kind of like that, except instead of a bouncy mat, you’ve got a whole planet in play. The epicenter, the spot where the plates first break free, is like the spot where you land on the trampoline. From there, the waves radiate outwards, causing the ground to shake with varying intensities depending on the strength of the earthquake and your distance from the epicenter.

Causes of Earthquakes

• Tectonic Plate Movements : Large pieces called tectonic plates divide the Earth’s surface. When these plates move against each other, they can get stuck and build up pressure. Eventually, this pressure is released, causing the ground to shake, which we feel is an earthquake.
• Faults and Fault Lines : Imagine the Earth’s crust as a giant puzzle of pieces. Sometimes, these pieces don’t fit perfectly together, and they can move past each other along lines called faults. An earthquake occurs when the rocks along a fault suddenly slip and move.
• Volcanic Activity : Sometimes, earthquakes can happen because of volcanic eruptions. When magma (hot molten rock) moves beneath the Earth’s surface, it can push against the surrounding rocks and cause them to break, leading to an earthquake.
• Human Activities : Human operations, such as mining or drilling for gas and oil, can cause earthquakes. When we dig deep into the Earth or inject fluids, we can change the pressure on the rocks and trigger earthquakes in areas that normally wouldn’t have them.
• Plate Boundaries : Most earthquakes happen along the edges of tectonic plates, where they meet. These places are called plate boundaries. Depending on how the plates are moving, earthquakes can occur at different plate boundaries, such as when plates collide, move apart, or slide past each other.

Types of Earthquake

Several types of earthquakes can be classified based on various factors, such as their underlying causes, the nature of their seismic waves, and their geographical distribution. Here are the primary types:

1. Tectonic Earthquakes : Tectonic Earthquakes are the most common and powerful type of earthquake. They occur when tectonic plates, the large rock slabs that make up Earth’s crust, move against each other. The movement can cause the plates to stick, then suddenly jerk free, releasing tremendous energy that travels through the Earth in waves. Tectonic earthquakes are further categorized based on the type of plate boundary involved, including:

• Strike-Slip Earthquakes : Occur at transform boundaries where plates slide past each other horizontally.
• Thrust (or Reverse) Earthquakes At convergent boundaries, one plate forces itself beneath another.
• Regular Fault Earthquakes : Occur at divergent boundaries where plates move away from each other, causing the crust to stretch and form faults.

2. Volcanic Earthquakes: These are smaller earthquakes that occur near volcanoes. They are caused by the movement of magma (molten rock) beneath the Earth’s surface. The movement of magma can crack the rock around the volcano, causing tremors. Volcanic earthquakes are usually much weaker than tectonic earthquakes.

• Collapse Earthquakes: Collapse Earthquakes are the weakest type of earthquake. They occur when the roofs of caves or mines collapse. Collapse earthquakes are usually very small and localized and rarely cause any damage.
• Explosion Earthquakes: These are earthquakes caused by human activity, such as bomb or mining explosions. They are similar to collapse earthquakes in that they are usually very small and localized.

Effects of Earthquake

The effects of an earthquake can be wide-ranging and impactful, affecting both the natural environment and human societies. Here are some of the key effects:

• Ground Shaking : Ground shaking is an earthquake’s most immediate and noticeable effect. This shaking can vary in intensity depending on the earthquake’s magnitude, the hypocenter’s depth (the point within the Earth where the earthquake originates), and the distance from the epicenter (the point on the Earth’s surface directly above the hypocenter). Severe shaking can cause buildings and structures to sway, crack, or collapse.
• Surface Rupture : In some cases, particularly in large earthquakes, the movement of tectonic plates can cause the Earth’s surface to rupture along fault lines. This can result in visible cracks or ground displacement , damaging roads, pipelines, and other infrastructure.
• Tsunamis : Earthquakes that occur underwater or near the ocean floor have the potential to generate tsunamis, which are large, destructive ocean waves. These waves can travel long distances across the ocean and cause widespread flooding and coastal erosion when they reach land.
• Landslides and Avalanches : The shaking and ground displacement caused by earthquakes can trigger landslides and avalanches, particularly in mountainous or hilly areas. These mass movements of rock, soil, and debris can bury homes, roads, and vegetation, posing additional hazards to human life and property.
• Liquefaction : In areas with loose, water-saturated soils, an earthquake’s intense shaking can cause the ground to behave like a liquid, a process known as liquefaction. This can result in the sinking or tilting of buildings, infrastructure, and other structures built on top of the affected soil.
• Infrastructure Damage : Earthquakes can cause extensive damage to buildings, bridges, roads, and other infrastructure, disrupting transportation networks, communication systems, and essential services such as water and power supply.
• Loss of Life and Injuries : The combined effects of ground shaking, structural collapse, and secondary hazards such as tsunamis and landslides can result in significant loss of life and injuries among affected populations.
• Psychological Impact : Earthquakes can have long-lasting psychological effects on individuals and communities, including anxiety, stress, and post-traumatic stress disorder (PTSD). The fear of aftershocks and the uncertainty surrounding recovery efforts can exacerbate these psychological impacts.
• Economic Consequences : Earthquakes can have profound economic consequences for affected regions, including property destruction, loss of life, and disruption of economic activities. These consequences include loss of income, decreased productivity, and increased financial strain on governments and relief agencies.

Mitigation and Preparedness

Mitigation and preparedness are crucial aspects of minimizing the impacts of earthquakes on human populations and infrastructure. Here are some key strategies and measures:

• Building Codes and Seismic Retrofitting : Strictly implementing and enforcing building codes while considering seismic hazards can ensure that structures are designed appropriately and constructed to withstand earthquake forces. Additionally, retrofitting older buildings and infrastructure to improve their earthquake resilience can help reduce the risk of collapse and casualties.
• Land Use Planning and Zoning : Proper land use planning and zoning can help mitigate the risk of earthquake-related hazards by restricting development in high-risk areas, such as floodplains, landslide-prone areas, and areas near fault lines. This can help minimize exposure to seismic hazards and reduce potential losses.
• Early Warning Systems : Developing and implementing early warning systems that detect seismic activity and provide warning before strong shaking arrives can help individuals and communities take protective actions, such as seeking shelter and shutting down critical infrastructure systems.
• Public Education and Awareness : Educating the public about earthquake risks, preparedness measures, and response procedures can help empower individuals and communities to take appropriate actions before, during, and after an earthquake. It includes conducting regular drills and exercises to practice emergency response plans.
• Infrastructure Resilience : Enhancing the resilience of critical infrastructure systems, such as transportation networks, utilities, and communication systems, can help minimize disruption and facilitate timely recovery efforts following an earthquake. It may involve reinforcing infrastructure components, diversifying supply chains, and incorporating redundancy into system designs.
• Community Preparedness and Resilience : Building community resilience through grassroots initiatives, community-based organizations, and partnerships between government agencies, non-profit organizations, and local stakeholders can help strengthen social cohesion, foster collective action, and enhance communities’ ability to withstand and recover from earthquakes.
• Emergency Response and Recovery Planning : Developing comprehensive recovery plans that outline various stakeholders’ roles, responsibilities, and procedures can help ensure a coordinated and effective response to earthquakes. These plans include pre-positioning emergency supplies, establishing evacuation routes, and coordinating search and rescue operations.
• International Cooperation and Collaboration : Promoting international cooperation and collaboration on earthquake research, monitoring, and preparedness can help improve the understanding of seismic hazards, enhance early warning capabilities, and facilitate the sharing of best practices and lessons learned across borders.

Staying Safe During an Earthquake

Staying safe during an earthquake requires quick thinking and decisive action. Here are some key steps to follow:

• Drop, Cover, and Hold On : When you feel the ground shaking, immediately drop to your hands and knees to prevent being knocked over. To shield yourself from falling objects, hide under a desk or other substantial piece of furniture. Hold on to the furniture with one hand and cover your head and neck with your other arm.
• Stay Indoors : If you’re inside a building, stay there during the earthquake. Move away from windows, glass doors, and exterior walls to avoid injury from broken glass or falling debris. Do not use elevators during an earthquake, as they may become stuck or malfunction.
• If You’re Outside : If you’re outdoors when an earthquake occurs, move to an open area away from buildings, trees, streetlights, and utility wires. Drop to the ground and cover your head and neck until the shaking stops.
• Stay Calm and Put: Stay calm during the earthquake and stay where you are until the shaking stops. Moving around during an earthquake can increase your risk of injury. Stay there and use a pillow to support your head and neck in bed.
• Be Prepared for Aftershocks : Smaller earthquakes, known as aftershocks, can happen hours or days after a bigger one. Take the same safety precautions as you did during the initial earthquake.
• Check for Gas Leaks and Fire Hazards : After the shaking stops, check for gas leaks, damaged electrical wires, and other fire hazards. If you smell gas or believe there might be a leak, immediately shut the gas supply at the main valve, then leave the area. Use a flashlight (not matches or candles) to inspect for damage, and Do not use electrical appliances until someone inspects them.
• Listen for Emergency Information : Listen to your local radio or television channels for updates and emergency information after the earthquake. Observe the guidance provided by emergency personnel and be ready to flee if needed.
• Assist Others : Check on family members, neighbors, and coworkers to ensure their safety and offer assistance. Be mindful of individuals with disabilities or special needs who may require additional assistance during an emergency.

After the Earthquake

Following the earthquake, you should do a few things to ensure you’re safe and okay, help others, and start healing. This is what you should do:

• Check for Injuries : Immediately after the shaking stops, check yourself and others for injuries. Provide first aid when necessary, and if there are any severe injuries, get medical help. Be mindful of broken glass, sharp objects, and unstable structures.
• Assess Damage : Survey your surroundings for damage to buildings, infrastructure, and utilities. In addition to looking for possible dangers like gas leaks, downed electrical lines, and falling debris, Verify that there are no structural issues, such as foundation, wall, or ceiling cracks.
• Evacuate if Necessary : If your home or building is severely damaged or emergency officials advise evacuation, leave the area immediately. Follow designated evacuation routes and assembly points, and bring essential items such as medications, important documents, and emergency supplies.
• Listen for Updates : Stay connected to local radio, television, or official social media channels for updates and instructions from emergency officials. Follow their guidance regarding evacuation orders, shelter locations, and safety precautions.
• Turn Off Utilities : If you suspect a gas leak or damage to electrical, water, or sewer lines, turn off the respective utilities at the main shut-off valves or switches. Avoid using open flames, electrical appliances, or running water until utilities have been inspected and deemed safe.
• Check on Neighbors and Loved Ones : Contact neighbors, family members, and friends to check their safety and offer assistance. Be prepared to provide aid, support, and comfort to those injured, displaced, or experiencing distress.
• Document Damage : Take photographs or videos of any damage to your property or belongings for insurance purposes. Keep records of repair costs and receipts, and communicate with insurance companies to help with the claims procedure.
• Secure Property : Secure or remove any hazardous items that could pose a risk of injury or further damage, such as broken glass, unstable furniture, or fallen objects. Cover broken windows and doors with plastic sheeting or boards to stop more exposure to the weather.
• Follow Recovery Procedures : Follow local guidelines and procedures for debris removal, building inspections, and recovery efforts. Cooperate with emergency responders, government agencies, and community organizations to facilitate recovery and rebuild affected areas.
• Take Care of Yourself : Practice self-care and prioritize your physical and emotional well-being after the earthquake. Get adequate rest, stay hydrated, and, if necessary, ask for help from family members or mental health specialists.

Essay on Earthquake

Essay Contents:

• Essay on the Effects of Earthquake

Essay # 2. Causes of Earthquake:

There are many causes for earthquakes. Among them tectonic movement of the earth, volcanic eruption, icefall and landslide are the main ones.

Tectonic Movement :

The material of the interior of the earth gradually contract due to loss of heat by radiation. As a result of this, some tectonic forces (tensional and compressional forces) are produced which shake the surface. These forces are mainly responsible for the formation of Fold Mountains and rift valleys. That is why, the earthquakes occur more frequently in the regions of Fold Mountain.

Volcanic Eruption :

During volcanic eruptions lava, ashes and steams come out with an enormous force. These cause earthquakes on the surrounding areas of the volcano.

Sometimes large blocks of ice fall into the valleys from a snow capped mountain. Such a fall may cause a minor earthquake.

Landslide :

In mining area sometimes a large portion of land falls into the vacant space below and causes earthquake of minor nature.

The other causes of earthquakes may be due to the various reasons depending upon their intensity.

The following are the major causes:

i. Superficial movements.

ii. Volcanic eruption.

iii. Faulting and folding.

iv. Earthquakes due to other causes.

Earthquakes due to superficial movements:

The feeble earthquakes are caused due to the superficial movements such as dynamic agencies operating upon the earth’s surface.

(i) The dashing of waves cause vibration along seashore.

(ii) Water descending along high waterfalls.

(iii) The snow falling (avalanche) down from high altitude causes ground vibration.

(iv) The movement of locomotive and working of heavy machinery produces feeble vibration, along the railway tracks and in industrial areas.

Earthquakes caused due to volcanic eruption:

Some of the volcanoes may also produce earthquakes such earthquakes are generally feeble or severe.

Earthquakes caused due to folding and faulting:

The earthquakes caused due to folding/faulting are more disastrous. They are known as tectonic earthquakes and directly or indirectly change the very structural features of the earth’s crust.

Earthquakes caused due to other causes:

Atomic minerals disintegrate emanating α (alpha), β (beta), ϒ (gamma) rays due to radioactivity or due to bombarding. This produces enormous amount of heat and energy within the crust of the earth, which may also initiate very severe earthquakes.

Atomic tests:

Atomic tests conducted in earth’s crust or oceans, which have become a common thing now-a-days, release enormous energy on account of sudden explosion, which follows initiation of earthquakes.

Rocks burst and blasting in the deep under mines generally initiates earthquake tremors.

Essay # 4. Prediction of Earthquakes :

The precise prediction about earthquake calamity is elusive though it is not impossible, since for human grey matter sky is the limit. Recently, the frequency of earthquake calamities in the region has attracted the attention of the scientists all over the world.

It has been observed that earthquake may occur and reoccur at the same places and new places but they do not have any regular scale or frequency. The scientists know that elastic strain is piling up along SAF (San Andreas Fault) since 1906, but they are unable to forecast the exact day, time and place.

In about half of the cases, just before the rocks reach the rupture point to announce the event, small foreshocks announce hours, days or even months before the climax shock, that stress has become critical. The long series of post event tremors indicate adjustments.

Sometimes, the break may be as large as the major shock. Unusual animal behaviour, fluctuations of ground water level in wells and springs and variation in the discharge of springs are the phenomena closely related to the development of fractures.

In China, about 90 per cent of the country is lying on the young and restless crust. Chinese have successfully employed most of the precursors in predicting major disasters and have specially mastered the art of closely monitoring and analysing normal behaviour of animals to forecast earthquakes.

The Haicheng earthquake of February 1975, of 7.3 magnitude, destroyed 90 per cent of the structures, but without loss of life due to timely evacuation of the population of nearly a million. There is evidence that full moon and associated high tides, excessive precipitation and sharp biometric gradient changes, and particularly another quake elsewhere act as ‘trigger’ for earthquake.

Essay # 5. Facts about Earthquakes :

I. Earthquakes do not kill people, structurally unsound buildings can do.

II. There is no foolproof mechanism or technology in the world to predict quakes.

III. Himalayas could be ‘overdue’ for a great earthquake, though no one knows when and where these will occur.

IV. Active thrust faults exist all across foothills of northern India, the north-east and into northern Pakistan.

V. The subcontinent is sitting on the highly seismic Indian plate, with some major fault lines. In fact, there is no safe zone in India.

VI. Of late, the Indian plate boundary has become very active. It is on gradual move, pushing against the Eurasian plate by 4-5cm every year.

VII. All the plates of India should have a disaster management authority to deal with any eventuality.

VIII. Building of laws formulated after 2001 Bhuj earthquake to ensure the construction of quake-proof houses have not been implemented by any state government.

IX. India is among the few countries with no regulatory mechanism to control building activities.

X. Tremors of the Muzzafarbad quake were felt as far as west Bengal.

XI. Disasters have left the 800 years old Qutub Minar with slight tilt, but it has survived several quakes in its life time.

Essay # 6. Classification of Earthquakes :

The earthquakes are classified on number of bases. Of these the depth of FOCUS, the cause, the intensity and magnitude of earthquakes are very important.

1. Classification based on depth of Focus:

Accordingly the earthquakes are termed as:

i. Shallow:

When the focus lies within 60 km.

ii. Intermediate:

When its focus lies within 60 to 300 km from the surface.

iii. Deep seated:

When the focus lies beyond the 300 km depth.

2. Classification based on origin:

The earthquakes are broadly classified into Tectonic and Non- Tectonic types. The tectonic earthquakes are directly related to the movements of crystal block along faults. They are generally very severe and area affected is often very great.

The non-tectonic type includes earthquakes due to number of causes such as:

i. Volcanic eruptions.

ii. Collapse of underground caverns.

iii. Superficial movement like landslides, etc.

3. A third way to classify the earthquakes is on the basis of their intensity, which is defined by the effects or degree of damage that an earthquake produces on the structure and features of the earth.

A numbers of scales of intensity have been suggested.

Some of them are:

i. Rossifeerets scale, and

ii. Mercale scale.

Richter’s scale:

This scale of intensity is adopted internationally. Charles F. Richter, an American Seismologist, devised the earthquake intensity scale. This is based in the total amount of energy released during an earthquake. The energy is called ‘magnitude’. The magnitude is calculated mathematically using the amount and duration of ground vibration/tremors as recorded by seismograph.

Essay # 7. Record of Earthquakes :

Seismograph:

The instrument used for recording the vibrations of the earth crust is known as ‘seismograph’.

The vibrations are recorded on a strip of paper or photograph film and the diagram is produced as shown:

Most seismographs contain a heavy weight suspended from a support, which is attached to bedrock. When waves from a distant earthquake reach the instrument the inertia of the weight keeps it stationary while the earth and support vibrate.

The movement of the earth in relation to the stationary weight is recorded on a rotating drum. Some seismographs detect horizontal motion while others detect vertical motion. The traces of the earthquake waves are usually recorded on a moving photographic paper as a series of zigzag lines.

With the help of seismograph the distance between the recording station and the epicentre is located or determined.

Essay # 8. Seismic Waves Produced during Earthquake :

At the time of earthquake three types of waves are produced from the focus Seismic waves are of three types—P waves, S waves and L waves.

Surface waves or L waves are responsible for causing earthquakes while the importance P and S waves are in study of earth’s interior. P and S waves travel through the interior of the earth and are reflected and refracted as they enter core and mantle layers.

P waves or Primary waves:

These are compressional waves, which cause the material of rock to vibrate in longitudinal direction. The primary waves travel faster, therefore, they reach the seismic station first.

They pass through solid as well as liquid media. The velocity of P waves from 5.5 to 13 km per second. These waves are also called as Push waves and are similar to Sound waves.

S waves or Secondary waves:

These are shear waves, which are transverse in nature, whose velocity is less than P waves. (The velocity of these waves varies from 3 to 7 km per second). The S waves travel through solids only and do not pass through liquid media.

L waves or Surface waves:

When primary and secondary waves reach the earth’s surface they are converted into longitudinal wave. L waves travel along the surface and cause earthquakes. They are traverse in nature and their velocity is much less than P and S waves (velocity varies from 4 km to 4.3 km per second.  

Essay # 9. Earthquakes Resisting Structures :

To build earthquake-resisting structure it is very essential to determine the probable intensity and magnitude in the concerned area. The history and record of previous earthquake and the knowledge of geology of the area are helpful in this connection.

i. Perfectly designed steel framed or reinforced ferro concrete structure possesses high degree of resistance from damage.

ii. It is recommended that in soft grounds where soil-bearing capacity is very poor, a concrete raft- foundation should be adopted for structures.

iii. The height of large building should not exceed 100 ft. The heavy loads near the top, like heavy stone work in coping and water tanks should be avoided.

iv. Bridges with screw pile foundation stand better to the shocks, than that of bridges with brick arches, and girder supported on stone work piers.

v. In house construction light roof (Low density concrete) and polymer construction material are recommended.

vi. Walls constructed in cement with wet bricks work bonded are essential.

vii. Careful planning can ensure that the streets are wide in relation to the height of buildings. Many of the deaths caused during earthquakes are due to the collapse of tall buildings into narrow streets.

viii. Reinforced concrete houses are relatively stable. Doors and windows are provided in alternate positions.

ix. The most secure house is one that will move as a unit.

x. The light weight material such as wood, hard board and light weight fire proof polymer products are employed in the construction of residential building particularly in strong seismic zones as found in Japan.

xi. The main aim of the engineer is to design and construct buildings, bridges and dams in seismic zones considering seismic co-efficient of the locality in such a way that they can minimise loss of life during an earthquake.

Essay # 10. Effects of Earthquake :

1. In cities seismic waves disrupt underground service such as water, gas pipelines, bursts causing fire.

2. Roads are fissured, railway lines are twisted, dams and bridges are destroyed, electrical transmission is snapped causing short circuit of electricity and out-break of fire hazards.

3. Buildings are damaged and people get frightened resulting in loss of life and property.

4. Permanent tilting of landmass may occur in certain areas, landslides may occur in hill regions.

5. Rivers change their courses; fissures are opened up in the ground, which may cause springs.

6. Earthquakes occurring below the ocean floor may cause heavy damage to coastal areas.

Various changes take place on the surface of the earth as a result of earthquake. Some areas may subside or rise-up due to earthquakes. The earthquakes may also bring about a change in surface drainage by causing landslides and damming of rivers. This leads to flood or formation of lakes in the upper reaches of the rivers.

Sometimes large areas may be raised up above sea level so that they become plains. Sometimes again, a large plain may sink and become part of a sea. Sedimentary rock layers may be folded by the pressure exerted by the earthquakes. Devastating sea waves are also caused by the earth tremors.

They often cause great loss to the coastal areas. Although earthquakes are generally disastrous, they sometimes do constructional work also. They can create lakes, plains and islands.

The earthquakes of Bihar (1903 and 1934), of Baluchistan (1935), of Tokyo (1923), of Assam (1897 and 1950) and recent earthquakes of Chile, Mexico, Yugoslavia and Iran caused great loss to human lives and property, and brought about many changes to the earth’s surface.

The recent earthquakes of Armenia (1988), Turkey (1999), India (2001), Pakistan-India (2005) and of Iran (1989, 2006) are also worth mentioning. Recently, the earthquake of March 11, 2011 of Japan has completely destroyed the city of FUKUSHIMA and also 4 nuclear reactors.

Earthquakes and Their Devastating Consequences Essay

Nature and its actions are often unpredictable and frightening. Almost every day, TV channels and news websites report on natural disasters in different parts of the world. Many of these events are caused by global warming and other climatic and environmental changes resulting from human activities. Although many natural disasters are natural and predictable, they cannot be managed or their consequences predetermined. One of these incidents is earthquakes, which occur everywhere with less or more force and threaten the lives and health of people.

An earthquake is one of the most ancient and frequent catastrophic events. Despite this, people have yet to determine where, when, and what strength the next earthquake will occur. It occurs when a sudden release of energy accumulates for a long time due to the movement of tectonic plates (Bolt). Imagine going to a coffee shop to have some caffeine boost, as you do every morning. You have already gotten used to the fact that many people are there at this time and have learned to maneuver, avoiding collisions. However, you were late this morning and could not join this usual flow of people. As a result, you run into another customer, and the coffee stain is spilling over your shirt and coffee shop floor. People are trying to get away from the ‘epicenter’ of events, and cafe workers are trying to eliminate the results of the morning ‘catastrophe’ as quickly as possible. Earthquakes occur on a much larger scale, and instead of a coffee stain, a disruption is formed in the earth’s surface, spreading for tens of miles.

The break in the ground surface is the most common cause of horrific consequences, and people often cannot get out of the epicenter of the incident. Seismologists study and predict possible earthquakes, but it is impossible to predict any natural phenomenon in detail. Tracking seismic waves and their properties, especially in areas with a greater likelihood of an earthquake, certainly helps to warn the population and take preventive measures (Bolt). Every year, hundreds of thousands of earthquakes occur worldwide, most of which are minor and not felt by people. However, about 50,000 earthquakes can be detected without the aid of special instruments, and more than 100 of them are strong enough to cause significant harm to people (Bolt para. 2). Moreover, today, earthquakes occur even in those regions that are less prone to them, and the recent earthquakes in Turkey and Syria confirm this.

The circumstances and the number of victims of this incident are simply shocking. Moreover, neither the people nor the authorities of Turkey and Syria were prepared for such a catastrophe, which led to even more victims and deaths. Imagine another situation, in the evening, you go to bed, preparing for a hard work week because tomorrow is Monday. Suddenly, in the middle of the night, it seems that the house is starting to stagger, and after a few minutes, you find yourself under the rubble of concrete slabs. The worst thing is that this is not a nightmare from which you can wake up but a new reality. That is exactly what happened on the night of February 6 in Turkey.

I was lucky, and I never found myself in the epicenter of an earthquake, and more precisely, I did not find myself in such a strong earthquake that I could feel. However, the news and photos from the scene in Turkey startled me. According to official information from the authorities, “approximately 7,000 buildings in the area have been damaged or destroyed” (Pamuk para. 24). This is approximately 25,000 victims who unknowingly slept in their beds. Moreover, this event was not limited to one region but moved about 60 miles and struck Turkey with another 7.5-magnitude earthquake (Pamuk para. 28). If at night the whole scale of the catastrophe was still not so visible, then in daylight, these events caused shock and chaos.

Any emergency is certainly accompanied by chaos, and this case is no exception. People who managed to escape the earthquake’s epicenter in time “wandered the streets in search of help or food” (Pamuk para. 28). Others looked for their relatives and friends who could remain under the rubble. The consequences of earthquakes are always unpredictable but are always accompanied by destruction and casualties among people. In addition, this natural event destroys infrastructure and communications, leaving the region isolated indefinitely. In southeastern Turkey, the earthquake destroyed water and heating systems, as well as serious problems with mobile communications (Pamuk). The inability to contact their relatives and friends who lived in the destroyed houses leads to even more panic and chaos.

Moreover, some consequences of earthquakes are not so obvious. For example, one of the most common consequences of earthquakes is tsunamis (Bolt para. 23). The wave covering the coastal regions is formed due to underwater earthquakes, which humans may not feel. The most devastating was the tsunami of December 26, 2004, in Indonesia, caused by the movement of tectonic plates on the ocean floor (Bolt para. 24). As a result, the infrastructure of cities was destroyed, but the most terrible consequence was the number of victims among people.

If people in Turkey had known about the impending earthquake, they would probably have gone to safer regions of the country, or at least would have left the city and would not have ended up under the concrete rubble of houses. If citizens and tourists in Indonesia had been warned of the magnitude of the coming tsunami, they might have moved away from the coast. It wouldn’t help protect the infrastructure or keep their homes intact, but it could save thousands of lives.

However, the world around us is unpredictable and impossible to control. Yet this does not mean we cannot reduce the negative effects of natural events. Firstly, when building houses, their location is taken into account. That applies not only to proximity to the city center or the presence of developed infrastructure but also to the seismic safety of the location (Bolt). Secondly, people should know the basic algorithms of behavior during natural events. Moreover, as Turkey’s practice shows, this is necessary not only in regions where earthquakes occur frequently but in all countries. Researchers, of course, are doing a lot to reduce the scale of catastrophes from natural events, but any precautions will be reasonable.

In conclusion, the world is amazing and interesting, but also dangerous and uncontrollable. Storms, floods, earthquakes, and other natural events occur daily and have devastating consequences. The damage they bring to people is impossible to predict, but their negative consequences can be reduced. Basic knowledge and precautions can help save thousands of lives. Even if nature cannot be controlled, it can and should be studied to improve our security.

How to Write an Essay About Earthquakes

Diana v. faustmann.

Earthquakes cover as much ground in essay writing as they do in the real world. You can relate a personal earthquake experience, describe the steps to become a seismologist, narrate the earthquake history of a certain location or compare earthquakes to other natural disasters. Then you can choose to describe your topic, narrate a specific incident, analyze earthquake effects or argue for a better earthquake coping mechanism. These rich options challenge you to narrow your focus and define your purpose upfront. Then use sound research and a simple essay format to convey your informed message about earthquakes clearly and concisely.

Narrow your focus. Choose an area about earthquakes that fascinates or intrigues you and then restrict your focus further within it. For example, go from earthquakes in general to the Haiti earthquake of 2010, and from its effect on the Haitian people to orphans specifically.

Decide on your angle. Perform cursory research on your selected topic and then decide whether you want to narrate, explain, analyze, argue or persuade your readers to take action.

Establish your thesis and identify several sub-topics that exemplify or otherwise support your thesis. Develop a thesis statement that contains both elements. For example, “Seismology is a sound career to consider. You work outdoors most of the time, study the causes and effects of earthquakes in depth, and help to discover ways to limit their damage.”

Outline your introduction, body and conclusion. Focus your research on the data that you need to amplify your sub-topics. For instance, for the sub-topic, “The Richter scale is an inadequate earthquake measurement tool,” in your outline, add three bullets corresponding to case studies that illustrate that claim.

Write your introductory paragraph to compel further reading. First, provide a lead-in that gives earthquakes an interesting or original slant. Then narrow your focus and end with a statement of your thesis. For example, “My family barely escaped calamity in last summer's earthquake. Many of our neighbors were not so lucky; they lost homes and lives. Clearly, our homes still don’t adequately protect us from shifts in the seismic plates beneath us. We need to better earthquake-proof our area with a building code that is stronger in three major areas: (a), (b) and (c).”

Assign one or two paragraphs to address each sub-topic. Begin each paragraph with a topic sentence followed by supporting facts or examples. For example, state that “Governments should discourage new developments over known earthquake faults.” Follow this topic sentence with a description of three communities that earthquakes virtually demolished.

End your essay clearly and confidently. Begin your conclusion with “in summary” or “in brief,” then restate your thesis and sub-topics. Engage your readers with one final, memorable or compelling statement or anecdote. For example, “Compassion can be as earth-shaking as an earthquake, but with the opposite effect. Investigate how you can help to rebuild the lives of Haitian earthquake orphans today.”

• Sometimes your research leads you to a different conclusion than your thesis originally set out to prove. Adjust your thesis statement accordingly.
• Keep your sentences short and coherent. As much as possible, use active verbs throughout.
• Use transitional expressions between sentences and paragraphs; words such as “moreover,” “consequently” and “finally,” help your readers follow your train of thought and move smoothly from one thought to the next.
• Review your essay for spelling and grammar errors and any weaknesses in its flow. If possible, recruit a friend to help you proofread your essay before you submit it.

Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami.

Earthquakes occur mainly as a result of plate tectonics, which involves blocks of the Earth moving about the Earth's surface. The blocks of rock move past each other along a fault. Smaller earthquakes, called foreshocks, may precede the main earthquake, and aftershocks may occur after the main earthquake. Earthquakes are mainly confined to specific areas of the Earth known as seismic zones, which coincide mainly with ocean trenches, mid-ocean ridges, and mountain ranges.

The point of origin of an earthquake is called the focus. The epicentre is the point on the Earth's surface directly above the focus. Most earthquake foci are within a few tens of kilometres of the Earth's surface. Earthquakes less than 70 km deep are classified as shallow-focus. Intermediate-focus earthquakes are 70-300 km deep, and deep-focus earthquakes more than 300 km deep. Shallow-focus earthquakes occur in all of the Earth's seismic zones, but intermediate- and deep-focus earthquakes are almost exclusively associated with seismic zones near ocean trenches.

The destructiveness of an earthquake depends on the size, the depth (shallow ones are more destructive) and the location. Earthquake size can be stated in terms of the damage caused (the intensity) or the amount of ground motion and the energy released by the earthquake (related to the Richter magnitude).

Download the Earthquake Essay Available on Vedantu’s Website.

Earthquakes are some of the most devastating natural disasters. Millions of dollars worth of property are damaged and a hundred die every time a big magnitude of eater quake strikes.  It is in this regard that everyone must read and know about earthquakes and be prepared to mitigate the damage. Furthermore, the topic of earthquakes is quite often asked in exams. Preparing for this topic will enable them to have an edge and score more marks in the English paper.

To serve the above-mentioned purpose, Vedantu has come up with the Earthquake essay. This essay is prepared by the experts who know what exactly is required to know and weeding out points that are not important. The essay is very precise and would surely allow students to successfully claim marks in the essay question and even stay prepared when an earthquake actually strikes.

What is an Earthquake?

When the earth’s surface shakes, the phenomenon is referred to as an earthquake. Precisely, the sudden trembling of the earth’s surface is the cause of an earthquake. Earthquakes are regarded as one of the deadliest natural disasters. Huge damage and loss of property are caused by earthquakes. There are various types of earthquakes. Some of them are severe in nature. The most dangerous thing about an earthquake is that it is quite unpredictable. It can cause several damages without any previous indication. The intensity of an earthquake is measured by the Richter’s scale. Generally, earthquakes occur due to the movement of tectonic plates under the earth’s surface.

Types of Earthquake

There are four kinds of earthquakes namely 

Tectonic Earthquake,

Volcanic Earthquake, 

Collapse Earthquake and 

Explosive Earthquake.

Tectonic Earthquake 

It is caused due to the movement of the slab of rocks of uneven shapes that lie underneath the earth’s crust. Apart from that, energy is stored in the earth’s crust. Tectonic plates are pushed away from each other or towards each other due to the energy. A pressure is formed because of the energy and movement as time passes. A fault line is formed due to severe pressure. The center point of this dispersion is the epicenter of the earthquake. Subsequently, traveling of the waves of energy from focus to the surface causes the tremor.

Volcanic Earthquake

The earthquake caused by volcanic activity is called a volcanic earthquake. These kinds of earthquakes are of weaker magnitudes. Volcanic earthquakes are categorized into two types. In the first type, which is called volcano-tectonic, shaking happens due to input or withdrawal of Magma. In the second type, which is termed as Long-period earthquake, tremors occur due to changing of pressure among the earth’s layers.

Collapse Earthquake

Collapse Earthquake is the third type of earthquake that occurs in the caverns and mines. This is another example of a weak magnitude earthquake. Mines collapsed due to underground blasts. Consequently, seismic waves are formed due to this collapsing. Earthquakes occur because of these seismic waves.

Explosive Earthquake

The fourth type of earthquake is called an explosive earthquake. This is caused due to the testing of nuclear weapons.

Effects of Earthquake

The effects of earthquakes are very severe and deadly. 

It can cause irreparable damage to property and loss of human lives. The lethality of an earthquake depends on its distance from the epicentre. 

Damage to establishments is the direct impact of an earthquake. In the hilly areas, several landslides are caused due to earthquakes.  

Another major impact of an earthquake is soil liquefaction. Losing the strength of water-saturated granular material is the cause behind this. The rigidity of soil is totally lost due to this.

Since the earthquake affects the electric power and gas lines, it can cause a fire to break out. 

Deadly Tsunamis are caused due to earthquakes. Gigantic sea waves are caused by the sudden or abnormal movement of huge volumes of water. This is called an earthquake in the ocean. When tsunamis hit the sea coasts, they cause a massive loss of lives and properties. 

Earthquake is termed as one of the most huge and lethal natural disasters in the world. It proves the fact that human beings are just nothing in front of nature. The sudden occurrence of earthquakes shocks everyone. Scientists are working rigorously to prevent the damage of earthquakes, but nothing fruitful has been achieved yet.

Examples of Devastating Earthquake

The city of Kobe in Japan witnessed a devastating earthquake on January  17, 1995, killing more than 6,000 and making more than 45,000 people homeless.  The magnitude of the quake was 6.9 at the moment which caused damage of around 100 million dollars.  The governor of Kobe spent years on reconstruction and made efforts to bring back fifty thousand people who had left home.  Japan geologically is a highly active country. It lies upon four major tectonic plates namely, Eurasian, Philippine, Pacific, and North American which frequently meet and interact.

The second incident is in Nepal where an earthquake struck on April 25, 2015. About 9000 people were killed and almost 600,000 structures were destroyed.  The magnitude of the quake was 7.9 and the repels were felt by neighbouring countries like Bangladesh, China and India.  The disaster caused severe damage of millions of dollars. All the countries across the world including India garnered to help Nepal by sending monetary aid, medical supplies, transport helicopters and others.

FAQs on Earthquake Essay

2. How to protect oneself during an earthquake?

Earthquakes could be very disastrous and can cause a lot of collateral damage.  During an earthquake you can look for the corners to hide. Another safe place to hide is under the table or under the bed. If one is sitting in a multistory building, avoid taking a lift and only use the stairs. In this kind of situation, one should never panic and stay calm.  Let the earthquake pass until then keep hiding in the safe spot. Once over, come out to evaluate the situation and take appropriate actions.

3. How to mitigate the effects of an earthquake?

Prevention is better than cure. It is always a better idea to take necessary actions before an earthquake has struck. In the first place, send a copy of all your documents to someone reliable. In case of an earthquake that destroys your important documents, there would always remain a facility to retrieve them.  Research and know if your city is in a seismic zone.  One should also take note of earthquakes during the construction of a house and lay emphasis on a seismic-proof house.

4. How can one teach people about the effects of an earthquake?

There are many ways one can raise awareness about the effects of earthquakes.  There is Youtube and Instagram which could be used to disseminate all the knowledge about the earthquake and its impact on humans.

Earthquake Cause and Effect Essay Sample

Earthquakes are one of the worst and deadliest natural disasters that can occur. They are due to different factors and leave behind after-effects in their wake. An earthquake is the sudden release of strain energy in the crust of the planet’s surface, which will result in shaking that resonates outwards from the source. Simply, it is the sudden shaking of the Earth’s surface and can also be called a quake, tremor, or tremblor.

Earthquakes come in different sizes, as some are weak and cannot be felt, while others are violent and can destroy cities. The frequency, size, and type of quakes experienced are called seismicity. Earthquakes can be a result of volcanic action too. Furthermore, they have various effects that disturb lives and property.

The Valdivia Earthquake, also known as the Great Chilean, is the most powerful earthquake ever recorded. It occurred on the 22 nd of May, 1960, with studies placing it between 9.4 and 9.6 on the moment magnitude scale. The main cause of the quake was tension released by the Nazca plate under the South American plate. The earthquake lasted for about 10 minutes and resulted in tsunamis that affected Hawaii, southern Chile, eastern New Zealand, the Aleutian Islands, Japan, southeast Australia, and the Philippines.

Earthquakes are one of the most destructive and fascinating natural disasters that can cause a huge amount of destruction, injuries, and even death, but what makes them so dangerous? In this earthquake cause and effect essay sample, we will attempt to answer this question and explore why earthquakes occur and what effects they can have on society and the environment. Earthquakes are caused by sudden movement of the earth’s crust resulting from a release of energy from the Earth’s interior, and can be triggered by many different things including human activities such as mining and construction. Understanding the processes behind earthquakes can help individuals and organizations make better plans for future mitigation and adaptation if an earthquake were to occur. Additionally, students can buy a coursework to learn how to plan for an earthquake and develop better understanding of how to prepare for and cope with natural disasters.

Causes of Earthquakes

The main cause of the quakes is the sudden release of stress from the faults in the Earth’s crust. In this guide on how to do a cause and effect essay , we will cover the causes of an earthquake. As the continuous motion of layers transpires, it causes a gradual build-up of pressure on both sides of a fault. This happens because of plate boundaries that are moving. Once the stress is too significant, it is released in a shaky movement. So, how are earthquakes caused? Here are the factors causing quakes.

Tectonic Movements of the Earth

One of the leading causes of an earthquake is movement from the tectonics. This is a shift of the planes making up the crust. Our planet consists of about a dozen major plates and several minor ones and is constantly changing.

The tectonic plates frequently move slowly, but sometimes, they get stuck because of friction. When the stress on the crust becomes more significant than the friction, an earthquake happens to release energy. This brings about a shaky feeling in steps through the planet’s crust. Little movement from the tectonic caused big things such as the happenings in the Ring of Fire.

Seismicity Ripples

Seismic waves are one of the causes of earthquakes. These are elastic ripples generated by an impulse, like an earthquake. The energy from the fault in the crust of the planet will radiate outward in different directions through seismicity. Think of it as ripples on a pond. As the ripples move through the surface, they shake the floor and anything on it. These can be in the form of ripples, which is when an earthquake happens more than once. North Carolina earthquake events occur because of seismicity, although they don’t have significant damage.

Compressions in the Crust of the Earth

Compression in the crust happens when plate tectonics are pushed together. The crust will become shorter and thicker, and depending on how it reacts to the force, it can lead to an earthquake. Due to compression, many quakes that occur in Australia are caused by these shifts along faults. Also, the main cause of the Northridge earthquake 1994 was the compressions on the planet’s surface.

Volcanic Eruptions

Volcanic eruptions are one of the less likely causes of an earthquake, depending on the volcano that erupts. The earthquake will be triggered when an explosion of an explosive volcano. These ripples have a wider effect than volcanic eruptions when they trigger an earthquake. In the case of volcanic eruptions, around 20 miles of the region around the volcano will be affected when it erupts. The largest volcanic tremor took place under Mount St. Helens in 1981 , with an intensity of 5.5.

Disturbances on the Surface

In general, an earthquake can be caused by disturbances on the surface. Technology advancement is one of the popular cause/effect essay topics , which is to some extent responsible for catastrophes like an earthquake. Humanity builds skyscrapers, constructs dams, and gets water from underground. Dams and reservoirs are known to trigger earthquakes, especially when a dam structure fails.

For instance, the 2008 happening in Sichuan , China, which killed about 70,000 persons, was triggered by the nearby Zipping Dam construction. Another disturbance is groundwater extraction, as this can destabilize an existing fault. Hydraulic fracking is a method of extracting natural resources. It works when shale formations underneath are injected with a mixture of chemicals and water at high pressure. Fracking has had such an impact on the environment causing earthquakes.

Big buildings and skyscrapers can also add significant pressure on the Earth’s surface and crack rudimentary rocks.

Writing a college admission essay can be a difficult and intimidating process. Fortunately, there are college admission essay services that can help. These services can help to ensure that the essay meets the requirements of the college. Ultimately, college admission essay service provide students with the resources needed to create a persuasive and effective essay that will make a lasting impression on college admissions committees.

Effects of Earthquakes

When an earthquake happens, it leaves behind five primary outcomes and fires, a significant secondary impact of quakes. The effects of earthquakes on the Earth are often devastating, with people getting killed and injured, buildings getting destroyed, and the emotional and mental health of those affected. That’s why the investigation of this topic is so crucial in minimizing the adverse outcomes.

If you need an essay discussing this or any similar topic, our custom essay writing services can help you get the job done quickly and professionally. Now, let’s get to the main repercussions of quakes.

Ground Shaking

One of the most negative effects of earthquakes is surface shaking. During this time, buildings can be damaged, humans and animals will not be able to stand up or move around, and objects can be tossed around regardless of how big they are. Lives are taken in earthquakes but not directly by the shaking. Instead, it is caused by shaking, like buildings collapsing or getting hit by large objects.

The shaking of unstable slopes and direct blowout during an earthquake can lead to a landslide. Landslides are harmful effects of earthquakes and can damage buildings, tumbling hilltop homes, and block roads and transport lines. When a landslide happens, parts of the planet slide down and block an area. It can affect transportation after the earthquake, causing increased expenditure and leading to injuries and death for people there.

Surface Rupture

Another effect of quakes is surface breaking, which happens when the earthquake breaks the surface. As the earthquake occurs along a fault-line, it breaks through the Earth’s surface and can damage roads, pipelines, railway lines, tunnels, and airport runways. They will be damaged in the aftermath of an earthquake. An example of surface damage during an earthquake was the 1906 quake in California. The main cause of the quake was a slip of the San Andreas fault. The San Andreas fault is a major fracture of the planet’s crust.

Although this is a less common effect, an earthquake causes a tsunami. Tsunamis are water or tidal shakes that cause grave danger to places around the world, especially those in the Pacific Northwest region. An earthquake can cause the seafloor to move vertically apart from the normal floor. This will shake up the ocean and come in a series of floods to the beach. Tsunamis can move more than 700 kilometers per hour, causing flooding. It can damage properties and lead to death and injury too. Places close to the ocean are often subjected to tsunamis during an earthquake.

Liquefaction

Liquefaction is one of the outcomes of an earthquake that happens on the unconsolidated surface. When sediment grains are made to float in groundwater, the soil will lose all its solidity, and this is liquefaction. Tremors and earthquakes can cause mud and sand to spray over a couple of meters, posing a danger to buildings, train lines, gas lines, roads, and airport runways. Buildings can tip over and sink because of the liquefied soils, as occurred in the 1964 Niigata earthquake in Japan. Even septic tanks and gas tanks can float to the surface. Liquefaction after earthquakes leads to damages worth millions of dollars.

Earthquakes can have devastating consequences, so learning more about their causes and effects can be extremely beneficial. Recently, scientists have made tremendous progress in understanding the mechanisms behind earthquakes. To develop a deeper understanding of earthquakes, students may be required to write a coursework for me exploring the causes and effects of them. For example, they can focus on exploring tectonic plates and how they move and affect the ground, as well as the effect of natural conditions like weather and climate on their development. Additionally, the effects of an earthquake, such as structural damage and the resulting landslides, tsunamis and fires, can be further investigated in other science studies.

This essay has highlighted the cause and effect of earthquakes.  Earthquakes are severe natural disasters caused by shifts in the crust of the Earth. Compressions on the planet’s surface, human disturbances like skyscrapers and dams, and tectonics moving can cause earthquakes.  When they occur, consequences like landslides, ruptures, tsunamis, and more will follow. Some of the top countries prone to quakes are China, Indonesia, Turkey, Peru, Iran, Turkey, the United States, Japan, and Italy. China has gone through 157 earthquakes between 1900 and 2016. People living in these areas have precautions taken to protect themselves from injury during an earthquake.

Essay on Earthquake

Essay generator.

An earthquake is a natural phenomenon that manifests the dynamic nature of our planet. It is a seismic event characterized by the shaking of the ground caused by the sudden release of energy in the Earth’s lithosphere. This energy creates seismic waves that propagate through the Earth’s surface, leading to the ground shaking that we perceive as an earthquake. This essay delves into the causes of earthquakes, their effects, and the measures that can be taken to mitigate their impact, aiming to provide a comprehensive overview suitable for students participating in an essay writing competition.

The Causes of Earthquakes

The primary cause of earthquakes is the tectonic movements in the Earth’s crust. The Earth’s lithosphere is divided into several tectonic plates that float on the semi-fluid asthenosphere beneath. These plates are constantly moving, albeit very slowly, due to the convective currents in the mantle. Earthquakes occur when the stress accumulated along the edges of these tectonic plates is released suddenly. This stress can build up due to several factors:

• Plate Tectonics: Most earthquakes are triggered by the movement of tectonic plates, either by sliding past one another, colliding, or moving apart.
• Volcanic Activity: Volcanic earthquakes are a result of the movement of magma within the Earth, leading to tremors.
• Human Activities: Human activities such as mining, reservoir-induced seismicity due to the filling of large reservoirs behind dams, and even the extraction or injection of fluids into the Earth can trigger earthquakes.

Measuring Earthquakes

Earthquakes are measured using two main scales: the Richter Scale and the Mercalli Intensity Scale. The Richter Scale quantifies the energy released by an earthquake, using a logarithmic scale where each whole number increase corresponds to a tenfold increase in measured amplitude and roughly 31.6 times more energy release. The Mercalli Intensity Scale, on the other hand, measures the effects of an earthquake at different locations, taking into account the human experiences and structural damages.

Effects of Earthquakes

The impact of an earthquake can range from negligible to catastrophic, depending on its magnitude, depth, and the area’s vulnerability. Some of the significant effects include:

• Ground Shaking: The most immediate and noticeable effect of an earthquake is the shaking of the ground. This shaking can range from mild to violent, causing buildings, bridges, and infrastructure to sway or vibrate. Severe ground shaking can lead to structural damage and collapse.
• Surface Rupture: In some earthquakes, the Earth’s surface can rupture along the fault line where the earthquake occurred. This can result in visible cracks and displacements of the ground, damaging roads, pipelines, and buildings.
• Building and Infrastructure Damage: Earthquakes can cause extensive damage to buildings, homes, and infrastructure, particularly in areas with poor construction standards or older structures that are not earthquake-resistant. Collapsed buildings can lead to casualties and destruction.
• Landslides: The shaking of the ground during an earthquake can trigger landslides on steep slopes, burying homes, roads, and people under debris. Landslides can be especially dangerous in hilly or mountainous regions.
• Tsunamis: Underwater earthquakes, particularly those occurring along tectonic plate boundaries, can generate tsunamis. These large ocean waves can inundate coastal areas, causing widespread destruction and loss of life.
• Aftershocks: Following the main earthquake, there are often aftershocks, which are smaller seismic events that continue to shake the affected region. Aftershocks can hamper rescue and recovery efforts and further damage weakened structures.
• Fires: Earthquakes can rupture gas lines and damage electrical systems, leading to fires. The destruction of fire-fighting infrastructure and limited access to water can make it challenging to control these fires.
• Soil Liquefaction: In certain soil types, the intense shaking from an earthquake can cause the ground to temporarily lose its strength and behave like a liquid. This phenomenon, known as soil liquefaction, can result in the sinking or tilting of structures.
• Infrastructure Disruption: Earthquakes can disrupt essential infrastructure, such as transportation networks, water supply systems, and communication lines. This can hinder emergency response efforts and recovery operations.
• Psychological Impact: Earthquakes can have a profound psychological impact on individuals and communities. The fear and trauma associated with the event, as well as the loss of homes and loved ones, can lead to long-term emotional and mental health challenges.
• Economic Consequences: The economic impact of earthquakes can be significant, affecting local industries, businesses, and employment. Rebuilding and recovery efforts often require substantial financial resources.
• Environmental Effects: Earthquakes can have environmental consequences, such as the release of toxins from damaged industrial facilities, contamination of water sources, and disruptions to ecosystems.
• Human Casualties: Earthquakes can result in injuries and loss of life, depending on factors like the population density of the affected area, the quality of building construction, and the preparedness of the community.
• Displacement of Communities: In the aftermath of a severe earthquake, many people may be displaced from their homes, leading to temporary shelters and overcrowded living conditions.
• Long-Term Recovery: Recovery and reconstruction efforts following a significant earthquake can take years or even decades. Communities must rebuild infrastructure, homes, and businesses while addressing the physical and emotional scars left by the event.

Mitigation and Preparedness

While earthquakes cannot be prevented, the risk they pose can be significantly reduced through effective mitigation and preparedness measures:

• Building Codes: Implementing and enforcing strict building codes that require structures to withstand seismic forces can greatly reduce the damage and casualties during an earthquake.
• Early Warning Systems: Advances in seismology have led to the development of early warning systems that can provide precious seconds or even minutes of warning before the seismic waves reach populated areas.
• Public Education and Preparedness: Educating the public about what to do before, during, and after an earthquake can save lives and reduce injuries. This includes conducting regular earthquake drills, preparing emergency kits, and developing evacuation plans.
• Research and Monitoring: Continuous research and monitoring of seismic activity can help in understanding earthquake mechanisms and potentially in predicting significant seismic events in the future.

In conclusion, Earthquakes are a powerful reminder of the dynamic nature of our planet. They bring to light the forces that continuously shape the Earth’s surface, often with profound impacts on human societies. Understanding the causes and effects of earthquakes is crucial for developing effective strategies to mitigate their impact. Through advancements in science and technology, along with effective public policy and community preparedness, we can reduce the risk posed by earthquakes and enhance our resilience to these inevitable natural events. As we continue to learn from each seismic event, it becomes increasingly possible to safeguard our communities, minimize loss, and navigate the challenges posed by these tremors of our planet

What Should You Do Before, During, and After an Earthquake?

This article was reviewed by a Caltech scientist.

It is impossible to predict when and where an earthquake will strike. Nonetheless, you can take steps before, during, and after a quake to help yourself stay safe and recover quickly.

Before an earthquake

Make sure you and your household are earthquake-ready:

• Secure heavy furniture and appliances – More than half of the injuries associated with the 1994 Northridge earthquake were caused by toppling objects. One way to protect yourself is to look around your home or workplace and make sure heavy furniture, such as bookcases and beds, as well as appliances, such as water heaters and televisions, are safely secured to the wall using straps, closed hooks, or wall studs. Large, heavy, or unstable items should be placed on low shelves, close to the floor, and away from doors and escape routes.
• Identify safe spots – Know where you can take cover in every room, for example under a sturdy table or desk. Conduct regular drills on how to drop, cover, and hold on.
• Have a plan – Make sure everyone in your household knows how to access disaster supplies, and whom to call and where to meet if an earthquake strikes when you are apart.
• Gather supplies – Have ample water and an emergency kit ready in your home, as well as smaller go-bags in your car, workplace, and any other places you might be when an earthquake hits. Your emergency supplies should be tailored for your specific needs, but common items include water, a first-aid kit, sturdy shoes, a portable radio, snacks, and emergency cash. FEMA and The Earthquake Country Alliance provide detailed checklists of items to include in an emergency kit.

During an earthquake

The safest steps to take in the middle of an earthquake depend on where you are:

• Indoors – Get under a desk or table, cover your head and neck with one arm or hand, and use your other arm or hand to hang on (drop, cover, and hold on) . If no shelter is available, move into a hallway or against an inside wall. If you use a wheelchair or walker with a seat, make sure your wheels are locked and remain seated until the shaking subsides. Stay away from windows, fireplaces, and heavy furniture or appliances, and do not use elevators. If you are in bed when an earthquake starts, do not get out of bed. Instead, lie face down to protect vital organs, and cover your head and neck with a pillow.
• Outdoors – Quickly find an open space away from buildings, power lines, and anything else that can topple on you. If you are driving, safely pull over and stop, and stay in your car until the shaking stops. Do not stop under bridges, overpasses, trees, or anything else that can strike your vehicle. If you are in a mountainous area, watch out for falling rocks and landslides, and if you are near the ocean during a severe earthquake, be mindful of tsunamis .

After an earthquake

After the shaking subsides, assess your wellbeing and that of those around you. Stay alert to new or continuing hazards.

• Conduct a safety check – Once you are in a safe place, check yourself and others for injuries, and call for help if needed. Look around to make sure you are not in danger from other hazards caused by the quake, such as gas leaks or fire. Wear boots or sturdy shoes to protect your feet from broken glass and debris.
• Get help, if needed – If you are trapped, cover your mouth, nose, and eyes against dust. Send a text and make noise to alert rescuers to your location.
• Be prepared for aftershocks – Aftershocks can be as strong as the original quake .
• Stay connected – If you have access to a battery-operated radio (perhaps in your car) or television, update yourself on the latest emergency information. Let friends and family know you are safe, but, if possible, minimize calls to help protect internet and telephone connectivity. You can also register on the American Red Cross " Safe and Well " website to let people know you are safe.

What not to do

• Avoid running to other rooms while the ground is still shaking.
• Do not seek shelter in doorways . They offer no protection against falling or flying objects.
• After a quake, do not use matches or lighters near stoves or barbecues until you are sure there are no gas leaks. If the gas is turned off, do not turn it back on by yourself; let the gas company do it.
• Do not call 911 unless you are experiencing a true emergency.

Paragraph on Earthquake

Students are often asked to write a paragraph on Earthquake in their schools. And if you’re also looking for the same, we have created 100-word, 200-word, and 250-word paragraphs on the topic.

Let’s take a look…

Paragraph on Earthquake in 100 Words

An earthquake is like when the earth shakes, similar to how a table might shake if you push it. This happens because the ground we walk on is made of giant pieces, called plates. Sometimes, these plates move and bump into each other, causing the ground to shake. We call this shaking an earthquake. Earthquakes can be small and gentle, hardly felt at all, or they can be big and strong, causing buildings to fall down. It’s important to know what to do when an earthquake happens to stay safe.

Paragraph on Earthquake in 200 Words

An earthquake is a sudden shaking or trembling of the Earth. It happens when pieces of the Earth’s crust, known as tectonic plates, move and slide past each other. Imagine if you rub your hands together very fast, they become hot and shaky, right? Something similar happens beneath the Earth’s surface too. The points where these plates meet are known as fault lines and this is where earthquakes usually occur. When an earthquake happens, it can cause the ground to shake, buildings to crumble, and in some cases, it can even cause big waves in the sea, known as tsunamis. Earthquakes can be scary, but scientists are working hard to predict when they might happen to keep us safe. It’s also important for us to learn about what to do if an earthquake happens, like finding a safe spot away from windows or tall objects that might fall. Remember, during an earthquake, we must stay calm and take quick steps to stay safe.

Paragraph on Earthquake in 250 Words

An earthquake is a sudden and violent shaking of the ground, often caused by the movement of tectonic plates beneath the Earth’s surface. Imagine two big pieces of rock pushing against each other until, finally, one gives way. That’s what happens during an earthquake. They can happen anywhere, at any time, and can cause great damage. The strength of an earthquake is measured by a tool called a seismograph, which uses a scale known as the Richter Scale. This scale can go from minor tremors that you might not even feel, to major quakes that can destroy entire cities. Earthquakes can cause buildings to collapse, landslides, and even tsunamis if they happen under the ocean. They can also open up big cracks in the ground. People all over the world work to predict when and where an earthquake will happen, but it is still a very hard thing to do accurately. It’s important to know what to do if an earthquake happens. If you’re indoors, stay there. Get under a desk or table and hold on, or stand against an inner wall. If you’re outside, get into an open area away from trees, buildings, walls and power lines. Following these simple steps can help keep you safe during an earthquake.

The surface of the Earth is made up of tectonic plates that lie beneath both the land and oceans of our planet. The movements of these plates can build mountains or cause volcanoes to erupt. The clash of these plates can also cause violent earthquakes, where Earth’s surface shakes. Earthquakes are more common in some parts of the world than others, because some places, like California, sit on top of the meeting point, or fault, of two plates. When those plates scrape against each other and cause an earthquake, the results can be deadly and devastating.

Floyd County keeps flooding and the federal government keeps coming to the rescue.

In July 2022, at least 40 people died and 300 homes were damaged in flooding across eastern Kentucky. It was the 13th time in 12 years that Floyd County was declared a federal disaster. These are disasters so costly that local governments feel they can’t pay for it all, so the governor asks the president to declare a disaster freeing up federal funds.

“After that flood I had 500 homeless people looking at me, ‘Judge what are we going to do’?” recalled Judge Robbie Williams, administrator for the county of a bit more than 35,000 people. “It’s overwhelming and it’s just a matter of time before it happens again.”

It did. In 2023, Floyd County was declared a disaster again for the 14th time, starting in 2011. And Floyd County isn’t even the nation’s most disaster-prone county. Neighboring Johnson County has 15 disasters declared by the Federal Emergency Management Agency since 2011.

When it comes to extreme weather and other so-called natural disasters, people generally look to the hurricane or earthquake-prone coasts and say that’s where the danger is. But that’s not where the highest concentration of federally declared disasters are, according to an atlas of 713 FEMA declared disasters created by Rebuild by Design and New York University. While most people in disasters think about federal government direct financial help to individual victims to pay for lost housing and businesses, the atlas focuses on the $60 billion pot of FEMA aid to governments.

Eight of the nine counties with the most federal declared disasters since 2011 — more than a dozen each — are in Kentucky, with the one in Vermont. These counties have four to five times the number of disaster as the national average of three in the past 13 years.

“California and Louisiana and I would say now even Texas, Florida, for sure, they soak up all the oxygen when you hear about these giant storms,” said atlas creator Amy Chester, director of the disaster prevention-focused Rebuild By Design nonprofit group. “But what you’re not hearing about are these storms that are happening all the time, and that’s just becoming like, regular to places like Vermont.” Chester also mentioned Tennessee, Oklahoma, Missisippi, Iowa and Alaska as hotspots.

“We want to show that climate change is already here,” Chester said of the data covers 2011 to 2023, but doesn’t include heat waves, drought or COVID. “Communities are suffering all over.”

Before she crunched the data, Chester said she figured Vermont would be a haven from climate change. Cooler. Inland. Instead it’s a disaster hot spot.

“It’s awful” Chester said. “It just keeps happening to them.”

Days after she said that Vermont flooded again , this time from the remnants of Hurricane Beryl.

Flooding is the most common disaster in the United States, according to FEMA. Since 2011, FEMA handed out more than $41 billion in aid following hurricanes, the most of any disaster type.

“What the data tell us is that the frequency and severity of disasters at local-state scales is increasing with rural, suburban, and urban places being affected nationwide,” Susan Cutter, co-director of the Hazards Vulnerability and Resilience Institute at the University of South Carolina, said in an email. She wasn’t part of Chester’s research. “More needs to be done to enhance resilience to reduce their impacts on people.”

The largest county in the nation that has not had a federally declared disaster since 2011 is Mecklenburg County, North Carolina, where the city of Charlotte is.

“We’ve been blessed,” said Charlotte emergency management chief Robert Graham, who attributes the lack of federal disasters to good luck, good government and good geography.

“We are protected from the coast somewhat,” Graham said of the inland county. “We don’t get all the impacts from the mountains. Charlotte seems to be in a, somewhat of a sweet spot.”

Graham said a cushy reserve fund and planning have prevented the city from having to go to the federal government for financial help after disasters like a 2019 flood. But he said he knows it’s only a matter of time before the city’s luck runs out.

Luck long abandoned eastern Kentucky.

In Floyd County, geography and government regulations make it tough, Williams said. The mountain-heavy county has people living in the narrow valley floor in old coal camps, he said. And when it rains, the ever-shallower creeks overflows.

“We’re seeing historic levels of flooding,” Williams said. “It’s only getting worse.”

Environmental regulations won’t let local officials dredge the creeks, which keep getting built up with silt coming down the mountains, often from development, Williams said. Some creeks decades ago were 20 feet deep but are now shallow enough to walk across, he said.

The problem is there is nowhere for the rain to go,” Williams said.

National Weather Service data shows that Floyd County now averages more than 50 inches of rain a year, up from 42 to 43 inches a year in the mid 1980s. Warmer air holds more moisture, with studies and statistics showing the Eastern United States is not only getting more rain, but more intense downpours that cause floods.

Floyd County’s government received more than $35 million in FEMA disaster aid since 2011. That’s not even near the top, where the big money went to places devastated by hurricanes.

Five counties — three of them in New York — received more than $1 billion in FEMA aid, led by Manhattan’s New York County, which got $8.9 billion, nearly all of it due to 2012’s Hurricane Sandy. All of the top five counties were struck by one or more hurricanes.

Chester’s group decided to look at congressional districts and how they compared in disasters, especially with a nearly evenly split House of Representatives.

Nearly 60 counties have had at least 10 federally declared disasters since 2011 and nearly 70% of them are represented in Congress by Republicans. About 280 counties have had no disasters in that time periods and 87% of them are represented by Democrats, according to the NYU data.

Chester noted that Republicans aren’t talking about climate change on the campaign trail, but said “research shows that extreme weather is not a partisan issue.”

More important is how state and local policies create or minimize risk for future disasters, said Samantha Montano, a professor of emergency management at the Massachusetts Maritime Academy. And in Floyd County the government using FEMA money is buying the homes of 150 residents to move them out of harm’s way, but some don’t want to leave, Williams said.

“Until we get those homes out of these flood ways... we’re still going to have these issues,” Williams said.

About Every 500 Years, a Major Quake Body-Slams Middle America

Experts can’t explain why, and big cities aren’t ready for another.

This article was originally published by Undark Magazine .

The first earthquake struck while the town was still asleep. Around 2 a.m. on December 16, 1811, residents of New Madrid—a small frontier settlement of 400 people in what is now southeastern Missouri—were jolted awake. Panicked townsfolk fled their homes as buildings collapsed and the smell of sulfur filled the air.

The episode didn’t last long. But the worst was yet to come. Nearly two months later, after dozens of aftershocks and another massive quake, the fault line running directly under the town ruptured. Eliza Bryan, a 31-year-old resident, watched in horror as the Mississippi River receded and swept away boats full of people. In nearby fields, geysers of sand erupted, and a rumble filled the air.

By the end, the town had dropped around 15 feet. Bryan and others spent a year and a half living in makeshift camps while they waited for the aftershocks to end. Four years later, the shocks had become less common. At last, the rattled townspeople began “to hope that ere long they will entirely cease,” Bryan wrote in a letter.

Whether Bryan’s hope will stand the test of time is an open question.

The U.S. Geological Survey released a report in December 2023 detailing the risk of dangerous earthquakes around the country. As expected on the hazard map, deep-red risk lines run through California and Alaska. But the map also sports a big bull’s-eye in the middle of the country—right over New Madrid.

The USGS estimates that the region has a 25 to 40 percent chance of a magnitude 6.0 or stronger earthquake in the next 50 years, and as much as a 10 percent chance of a repeat of the 1811–12 sequence. Although the risk is much lower compared with, say, parts of California, experts say that when it comes to earthquake resistance, the New Madrid seismic region suffers from inadequate building codes and infrastructure.

Caught in this seismic splash zone are millions of people living across five states—mostly in Tennessee and Missouri, as well as Kentucky, Illinois, and Arkansas—and two major cities, Memphis and St. Louis. Mississippi, Alabama, and Indiana have also been noted as places of concern.

In response to the potential for calamity, geologists have learned a lot about this odd earthquake hot spot over the past few decades. Yet one mystery has persisted: why earthquakes even happen here in the first place.

This is a problem, experts say. Without a clear mechanism for why the New Madrid area experiences earthquakes, scientists are still struggling to answer some of the most basic questions, such as when—or even if—another large earthquake will strike the region. In Missouri today, earthquakes are “not as front of mind” as other natural disasters, says Jeff Briggs, the earthquake program manager for the Missouri State Emergency Management Agency.

But when the next big shake comes, he says, “it’s going to be the biggest natural disaster this state has ever experienced.”

Sizing up earthquake risk isn’t easy—especially when a seismic zone is smack dab in the middle of a tectonic plate.

Up until recently, the 1811 and 1812 quakes were considered “freak events,” says Martitia Tuttle, a paleoseismologist at M. Tuttle and Associates, an earthquake-risk consulting company. Earthquakes occur when a subterranean strain that was building for centuries is released in seconds. That usually happens near plate-tectonic boundaries, where massive plates rub against each other.

But exceptions happen. For instance, the New York area was jolted by a sudden seismic shock in April, despite being thousands of miles from the closest plate boundary.

But just because areas such as New York are far from a plate boundary today doesn’t mean that was always the case—and many regions have the scars to prove it. Researchers have mapped out three currently active ancient fault lines—fissures in the Earth’s crust—in the New Madrid area that formed about 500 million years ago, at a time when the North American plate tried and failed to pull itself apart. Now those fault lines form weak zones where stress in the Earth can build and eventually break into earthquakes.

Why these fault lines are seismically active, yet neighboring ones aren’t, is less clear. “It’s really one of the most enigmatic seismic zones on the planet,” says Eric Sandvol, a seismologist at the University of Missouri. “We’re not supposed to have earthquakes here.”

Scientists have suggested that the movement of the North American plate westward is driving stress, or that earth bounding back after the crush of massive glaciers during the Ice Age is to blame. Some have also pointed to a pillow-shaped rock underneath the seismic zone as a factor.

But researchers simply “don’t have a smoking-gun stress source” and are unlikely to anytime soon, explains Eunseo Choi, a geophysicist at the Center for Earthquake Research and Information at the University of Memphis.

That matters because measuring stress buildup is a great way to predict earthquake hazards. The telltale ripping of earth along the surface—a sign of stress buildup—is easy to see in places such as California where tectonic plates meet. Yet until recently, researchers working in the New Madrid area weren’t even able to prove that the ground in the region was moving at all, because the movement there is far harder to detect. The lack of obvious stress buildup led some scientists to suggest that New Madrid might not be gearing up for another earthquake. Yet in 2015, scientists published data that showed that the ground near fault lines was in fact creeping —albeit slowly.

But researchers still don’t know exactly how much stress is building below the surface, Choi says.

With modern technology, people can look at celestial bodies light-years away, he says. “But ironically, we don’t really see that well just a few kilometers down from our surface.”

Read: Earthquakes are unlike any other environmental disaster

On a cloudy day in May, the geologist Roy Van Arsdale is driving on top of the Reelfoot fault line in western Tennessee. The Mississippi River valley extends on terrain as flat as Kansas for miles. Only some towns have the slightest bit of elevation.

Settlers in the region built anywhere they could to escape the annual spring floods. In New Madrid, that meant building where earthquakes had uplifted the earth. Van Arsdale pulls off the main road to park behind a prison complex. At odds with the rest of the countryside, a long, linear mound of earth juts out from beneath a prison fence and into a neighboring cornfield. It’s the fault line. If another major earthquake were to happen, Van Arsdale says, “they’d be in trouble.”

Van Arsdale has spent his career trying to understand why the region experiences earthquakes. In the 1970s, the nuclear-power industry planned on building power plants along the Mississippi and Ohio Rivers. But the specter of the 1811 and 1812 quakes raised concerns, so geologists like Van Arsdale were brought in to try to reconstruct the area’s seismic history.

The geologist treks across a small drainage ditch and onto the fault line. Dragonflies dart everywhere as Van Arsdale points to where, to the north, the fault line hits a levee—the massive engineered earthwork that holds back the annual Mississippi floods. When Van Arsdale and other research groups dug into this fault line decades ago, they found traces of the 1811 and 1812 quakes, as well as older ruptures dating back to the 15th and tenth centuries.

This work helped reveal that the New Madrid Seismic Zone has popped out major earthquakes—of 7.0 magnitude or greater—every 500 years or so for the past five millennia. Traces of older earthquakes may also exist, but scientists have yet to find them. Work by other researchers on sand blows—those geysers of sand that Bryan saw back in 1812—revealed that the 1811–12 pattern of three earthquakes hitting one right after the other wasn’t an aberration. The seismic events of the 15th and tenth centuries also likely involved multiple major quakes, one right after the other.

This research suggested that another major set of quakes was possible—and that if one happened, the area “should expect two more” in quick succession, Van Arsdale says.

A rough span of 500 years between major-earthquake events potentially puts a lot of time before the next big one. But many experts say the region is still largely unprepared for even moderate shaking.

Many parts of Alaska—which experiences large quakes more frequently—put in strict building codes after an earthquake devastated the state in 1964. Those building codes are thought to be why Anchorage survived a 7.0 earthquake in 2018 with only minimal damage and no deaths.

In contrast, many states in the New Madrid region began including earthquake provisions in their building codes only in the early 2000s, meaning anything built prior to that is prone to collapse. In Tennessee, jurisdictions can decide whether to opt in to building codes with earthquake provisions, while other states—like Missouri—don’t have statewide building codes at all, though there are efforts to change that.

That has experts worried. “Human bodies don’t stand up well to falling building parts,” says Chris Cramer, a geophysicist who works on earthquake hazards at the Center for Earthquake Research and Information at the University of Memphis. He estimated that a major earthquake near New Madrid would cost the U.S. an average of $10 billion a year for 100 years, from damaged buildings and lost infrastructure. For an aging Memphis—which is only roughly 40 miles from the southern edge of one fault line in the New Madrid system—even a moderate earthquake could cause considerable damage.

St. Louis is another city near the bull’s-eye. As with other places in Missouri, “we know that a lot of people are living in buildings that are not ready for a big earthquake,” says Briggs, who works for Missouri’s Seismic Safety Commission, a committee of experts appointed by the governor to help the state prepare for earthquakes.

Memphis and St. Louis have started to retrofit bridges in preparation. Newer buildings, especially taller ones, are built with shaking in mind. But “while progress has been made, there’s still a considerable way to go to ensure the resilience of buildings and infrastructure,” Alicia Tate-Nadeau, the director of the Illinois Emergency Management Agency and Office of Homeland Security, wrote in an email to Undark. To deal with this, that state has adopted international building codes with seismic provisions. These won’t become mandatory across Illinois until 2025.

But federal funding for earthquake preparation is also not thick on the ground, says Patrick Sheehan, the director of the Tennessee Emergency Management Agency. He highlighted that in 2024, the Federal Emergency Management Agency will have a little more than $2 million to distribute to states and territories for earthquake education and risk reduction. “That’s a pittance,” Sheehan says. “I think our nation could do a better job of investing in this.”

When contacted for comment, the FEMA press office confirmed that the 2024 fiscal year budgeted more than $2 million for individual state earthquake assistance, to be distributed through grants. But it said that the total amount allocated for the National Earthquake Hazards Reduction Program, or NEHRP—a major government initiative to reduce risk, educate the public, and research earthquake impacts in the U.S.—totals $8.5 million. The press office also added that there are natural-hazard mitigation funds through other programs that states, tribes, and territories can apply for as well.

Much of the funding distributed through the NEHRP goes toward raising awareness of earthquake risk. Arkansas, for example, qualifies for a grant of roughly $70,000, which can go toward increasing “community preparedness and knowledge of the threat of an earthquake,” wrote Hilda Booth, the earthquake program manager at the Arkansas Department of Public Safety, in an email to Undark.

Kentucky, Indiana, and Alabama’s emergency-management agencies did not respond to requests for comment. The Emergency Management Agency of Mississippi did not answer written questions sent by Undark.

In the New Madrid region, at least, “there’s a long way to go,” Briggs says. “I don’t know that we’ll ever get there.”

To work on earthquakes in the central United States is to trade in uncertainty. The region experiences about 200 small earthquakes every year. And still, when it comes to major quakes, “they can’t say that it will happen, because we don’t know that,” says Seth Stein, an earthquake seismologist and emeritus professor at Northwestern University.

Even Van Arsdale can see an earthquake-free future for New Madrid. His theory is that the Reelfoot fault and other rifts in the area were strained and activated only when the Mississippi River Valley eroded the land above them—creating a way for that pressure to be released. In this scenario, New Madrid might be winding down seismically.

But to others, the trend is clear: “It’s not whether they’ll occur, but when and where,” Tuttle says.

Not knowing the physics behind earthquakes in the area has made predicting future events tough. So, while scientists try to untangle the mysteries of the New Madrid Seismic Zone, some states and nonprofits are doing their best to get locals ready for the next earthquake.

“We know from research and past events that we’re capable of having large earthquakes in this area again, and at any time,” says Brian Blake, the executive director of the Central United States Earthquake Consortium, a nonprofit devoted to earthquake planning, education, and mitigation. “Our job, regardless of the mechanism that causes earthquakes, is to prepare.”

In Missouri, Briggs and his agency have developed an emergency plan for the next big one. The agency’s headquarters in Jefferson City has an underground facility that they can use to coordinate relief after a disaster. In the meantime, his team heads out to test the structural integrity of schools and other significant buildings in the southeastern corner of Missouri to see whether they can withstand shaking.

Despite this preparation, there appears to be no sense of urgency in the town of New Madrid, which had 2,700 residents as of 2020 and has a largely empty main street.

On the levee, a sign incorrectly announces the location of a fault line. The actual rift runs west of town, says Jeff Grunwald, an administrator at the New Madrid Historical Museum. The 1811 and 1812 quakes are a major draw for the 5,000 or so annual visitors to the museum.

But locals think about earthquakes—and the risk they pose—“very, very, little,” he says. “People have lives to lead.”

‘Tacos forever’: 101 reasons to love Los Angeles

• Copy Link URL Copied!

101 tacos for Jonathan Gold’s birthday, plus pizza box mysteries, Star Leaf mysteries and the mystery of who is buying Erewhon’s “raw animal smoothie.” Also a new restaurant from the Hundreds, San Diego eating and drinking, defending the street vendor defenders and the unexpected Little Armenia store for the best water selection in L.A. I’m Laurie Ochoa, general manager of L.A. Times Food, with this week’s Tasting Notes.

‘Tacos forever’

“The first time I came to L.A.,” chef René Redzepi said about Jonathan Gold during a Los Angeles screening event for the new Apple TV+ series “Omnivore,” “he picked me up in his pickup truck. And we ate tacos for like seven hours.”

“I have a similar J. Gold story,” said author and “Omnivore” co-creator Matt Goulding . “He came in his pickup truck and we ate tacos for six hours.”

Tacos frequently work their way into the narrative of the stories people tell about Jonathan Gold — whose professional history with this paper before he became a restaurant critic, began in the 1980s with phone calls he made under a pseudonym to cajole then-L.A. Times music critic Robert Hilburn into seeing one of the punk shows he’d booked at Hollywood’s old Anti-Club (and where he sometimes played a cello through a Marshall stack with his band Tank Burial while wearing an eyepatch).

Get to know Los Angeles through the tacos that bring it to life. From restaurants to trucks to carts and more, here’s 101 of the city’s best.

Last Saturday night, at downtown L.A.’s Zipper Concert Hall , during the Q&A following the “Omnivore” screening, the evening’s host, Ken Concepcion of the cookbook store Now Serving , asked Redzepi, Goulding and on-stage interviewer Evan Kleiman of KCRW’s “ Good Food ,” if they could share any stories about what Anthony Bourdain and Jonathan loved about Los Angeles. Both died in 2018 and, as Concepcion pointed out, the next day would be the six-year anniversary of Jonathan’s death. (Tomorrow, by the way, would have been Jonathan’s birthday.)

“Omnivore’s” Redzepi and Goulding — who were recently interviewed by The Times’ Karen Kaplan about the big ideas in their “ Planet Earth “-inspired series and about eating insects — had less to say about Los Angeles and Bourdain, the world traveler who made his name in New York. Their meaningful encounters with him were in other places. But Jonathan, in the appreciation he wrote just after Bourdain’s death, said this about the first time he met the chef-turned-author in New York: “He interrogated me about an L.A. Times review I’d written of Oki Dog a few years earlier, and why I was sending him to an iffy Los Angeles neighborhood to eat pastrami burritos and whether the hot dog wrapped into a tortilla with fried cabbage said more about L.A.’s changing demographics or about my dubious taste.” I’ll note that Oki Dog endures today.

Much easier for Redzepi and Goulding, were stories about Jonathan and Los Angeles ... and tacos.

“He saw that the care and the dedication is the same whether you’re doing tacos or fine dining,” Redzepi said. “If they had the dedication, he’d find them and put them forward.”

Jonathan loved tacos so much that when his weekly reviews weren’t enough to contain L.A.’s ever-growing taquero landscape, he started a Taco Tuesday column . Many of my memories of riding in Jonathan’s pickup truck with our two children involve stopping for tacos.

In 2018, L.A. Taco’s Erick Galindo collected some of Jonathan’s essential taco quotes .

The most memorable, from the “City of Gold” documentary directed by Laura Gabbert : “Taco should be a verb.”

The most emotional: “A taco, it could be argued, is the basic unit of consumption in Southern California. ... When we move to New York or Paris, it is tacos that haunt our dreams; when we are hungry after a night of dancing, it is the taqueros who nourish us, who appear precisely where and when we need them the most.”

And when he’d give an autograph or dedicate a copy of his “Counter Intelligence” book for fans, he usually signed off with two words: “Tacos forever.”

Forever is a big wish, but six years after Jonathan’s death, the taco scene in Southern California has grown exponentially. We’ve seen a profusion of regional styles from all over Mexico appearing at sidewalk stands across the city plus new variations coming from other cultures. Food editor Daniel Hernandez , in his essay that leads our just-published online guide to the 101 best tacos in Los Angeles (and in a special print section in tomorrow’s Sunday paper for subscribers and on sale at our L.A. Times store ), argues that Los Angeles is the most taco-diverse city in the world.

He pinpoints “the modern period of L.A.’s taco obsession” to “the arrival of the taco truck in Los Angeles in 1974.” That’s when the late King Taco founder Raul Martinez Sr . “parked a converted ice cream van next to an East L.A. bar and sold $70 worth of tacos.”

With such a rich taco scene, it only made sense for us to try to map out 101 of the best places to eat tacos in Southern California. The process, undertaken by Bill Addison, Stephanie Breijo, Jenn Harris, Cindy Carcamo, Sarah Mosqueda, Danielle Dorsey, Betty Hallock, Hernandez and me — was far from simple. Assistant food editor Dorsey explains how the project came together, starting with the initial idea in 2022:

“Altogether, the nine editors and writers who worked on the guide tried hundreds of tacos across almost every L.A. neighborhood and as far as Antelope Valley and the southern end of Orange County,” Dorsey writes. “We visited Michelin-nodded taquerias and humble puestos with equal exuberance, tapping colleagues, friends, family, local chefs and celebrities for recommendations along the way.”

Many of those recommendations — from Tyler the Creator , chef José Andrés , L.A. Chargers head coach Jim Harbaugh , musician Aaron Frazer , actor Ty Burrell , Dodgers pitcher Anthony Banda , real chef and fictional Fak brother Matty Matheson and more — were assembled by our summer intern Bryan A’Hearn into one article in the series.

We also mapped L.A.’s 18 best places to get vegetarian and vegan tacos and provided a glossary of taco lingo . Plus, Addison, in his role as restaurant critic, went through the 101 taco list and chose his 10 favorite tacos in L.A. — among them are last year’s Restaurant of the Year, Holbox , and this year’s Gold Award winner, Mariscos Jalisco . (Side note: Tickets are now on sale for this year’s Restaurant of the Year [ Baroo] and Gold Award presentations at Food Bowl on Sept. 20 at the Paramount Pictures Studio Backlot .)

Addison also choose Tacos Los Güichos , which serves the al pastor taco he “loves most in Los Angeles.” It happens to be the site of one of my favorite pictures of Jonathan and tacos (see above).

I can’t say that Jonathan would agree with the 101 tacos list that emerged from the process. And with new taco stands opening each month our list could look very different in a year’s time. We’re already collecting reader recommendations for further taco research — add your favorite place in the form linked here . But I do know that he would be please to find that the taco scene in Los Angeles is thriving.

As Hernandez wrote in his essay: “In Los Angeles, the taco is our avatar. It is who we are .”

Enjoy your delicious moments ... or else! Times reporter Daniel Miller — never one to ignore life’s mysteries big and small — wanted to know more about the pizza box that has intrigued and often disturbed pizza customers for years. “What’s the ... deal with this pizza box? Who designed it? ... Are there other pizza boxes that even come close to being this weird?” A fascinating read .

No, they want to make a point.”
• And Alana Hope Levinson writes that the best water in L.A. is not at Erewhon, but at a “ secret oasis ... in Little Armenia. ”

Venezuela’s Autocrat Is Declared Winner of High-Stakes Election

The result, which would give Nicolás Maduro six more years as president, is likely to be disputed by the opposition. The voting was riddled with irregularities.

By Anatoly Kurmanaev Frances Robles and Julie Turkewitz

Anatoly Kurmanaev and Frances Robles reported from Caracas, Venezuela, and Julie Turkewitz from Bogotá, Colombia.

Venezuela’s authoritarian leader, Nicolás Maduro, was declared the winner of a high-stakes presidential vote by the country’s election authority early Monday, a result that would extend his party’s rule into a third decade.

The vote was riddled with irregularities, and citizens were angrily protesting the government’s actions at voting centers even as the results were announced.

With 80 percent of voting stations counted, the election authority claimed that Mr. Maduro had received 51.2 percent of the vote, while his closest competitor, Edmundo González, had received 44.2 percent.

The result is very likely to be disputed by the country’s opposition, which for the first time in years believed it had a shot at ousting Mr. Maduro at the ballot box. Frustration over the outcome could plunge the oil-rich, crisis-laden nation into a period of deep uncertainty, with concern that street demonstrations could follow.

In the past, security forces aligned with Mr. Maduro have crushed protests with violence. The election body that declared the victory is led by a longtime ally of the president.

During Mr. Maduro’s party’s 25 years in power, it has presided over an economic contraction unlike any seen outside war and has become the source of one of the largest migrant crises in the world.
