The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.
On 4 November 2024, the volcano spewed molten debris at several villages some 4 km (2.5 mi) away, destroying homes and killing at least nine. [74] The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km (4.3 mi) radius around the volcano be evacuated. [75] Seven villages were affected by the eruption. [76]

The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...

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.
The volcanic explosivity index (commonly shortened to VEI) is a scale, from 0 to 8, for measuring the strength of eruptions but does not capture all of the properties that may be perceived to be important. It is used by the Smithsonian Institution's Global Volcanism Program in assessing the impact of historic and prehistoric lava flows.
