The theory is further supported by numerical modeling that calculated that the potential energy of the trapped compressed gas matched independent observations of the scale of the eruption, which has been assessed to have had a Volcanic Explosivity Index of 6. "Not only does the paper suggest that the Hunga eruption was gas-driven but proposes that this mechanism may be characteristic of ...
Report on Nyiragongo (DR Congo)
It contains a 1.2 km-wide summit crater with a lava lake that has been active since at least 1971. Lava flows have been a hazard in the past for the nearby city of Goma (15 km S); the most recent documented lava flows occurred in April 2019 from a secondary cone that had formed in February 2016, accompanied by ejecta (BGVN 44:05).

White Island Volcano Case Study
Twenty-seven of the 31 people injured in the eruption of the Whakaari/White Island volcano had burns to more than 30% of their body. The bodies of two victims have not been recovered and may have been lost to the sea. The ongoing seismic and volcanic activity in the area and subsequently heavy rainfall as well as low visibility and toxic gases ...

Source reservoir controls on the size, frequency, and ...
Large-scale, explosive volcanic eruptions are one of the Earth's most hazardous natural phenomena. We demonstrate that their size, frequency, and composition can be explained by processes in long-lived, high-crystallinity source reservoirs that control the episodic creation of large volumes of eruptible silicic magma and its delivery to the subvolcanic chamber where it is stored before eruption.
From anecdotes to quantification: advances in characterizing volcanic
Over the past 20 years, our understanding of volcanic eruption impacts on the built environment has transformed from being primarily observational with small datasets to one grounded in field investigations, laboratory experiments, and quantitative modeling, with an emphasis on stakeholder collaboration and co-creation. Here, we summarize key advances and knowledge gaps of impacts across ...
