To compare, Mt. St. Helens' eruption in 1980 was a level 4. Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera.
(The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .)
The INGV recorded 1,252 earthquakes in the Campi Flegrei area in the month of April 2024, most with a magnitude less than 1.0. ... The last major eruption of the supervolcano was in 1538, which ...
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming .
Seven villages were affected by the eruption. [76] A larger eruption occurred on 7 November. [77] On 8 November, the volcano erupted several times, one bearing an ash plume with a height reaching 10 km (6.2 mi). [78] On 9 November, it erupted again, scrambling authorities to evacuate approximately 16,000 people from nearby villages. [79] 2 ...
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time. Numbers indicate millions of years before ...
