VEI and ejecta volume correlation. 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.

Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8; Trans-Mexican Volcanic Belt – Active volcanic belt that covers central-southern Mexico; Volcanic arc – Chain of volcanoes formed above a subducting plate; Volcanic explosivity index – Predictive Qualitative scale for explosiveness of volcanic ...
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 ...
Satellite images of the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai. This is a list of volcanoes that have had large explosive eruptions during the Holocene (since about 11,650 years Before Present), with a volcanic explosivity index (VEI) of 5 or higher, or a plume height of at least 30 km.

Technically, there's no official definition for a supervolcano structure other than it being capable of eruptions of at least a seven on the volcanic explosivity index. A volcanic eruption that ...
