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.
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 ...

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 caldera formed during the last of three supereruptions over the past 2.1 million years: the Huckleberry Ridge eruption 2.1 million years ago (which created the Island Park Caldera and the Huckleberry Ridge Tuff), the Mesa Falls eruption 1.3 million years ago (which created the Henry's Fork Caldera and the Mesa Falls Tuff), and the Lava ...
Scientists working in Yellowstone National Park say the supervolvcano underneath may blow sooner than thought and could wipe out life on the planet.
Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
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 ...
