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.
Volcano guy 14:20, 5 January 2017 (UTC) User:Tony, your link is to Diversity index, i.e. a diversity index, of which there are many, so I think it is not a proper noun. There is only one Volcanic Explosivity Index, i.e. the Volcanic Explosivity Index, which I think is a proper noun. GeoWriter 14:45, 5 January 2017 (UTC)
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 ash fall pelted the capital and La Aurora International Airport. The National Coordinator for Disaster Reduction (CONRED) declared a red alert for the communities near the volcano and recommended the evacuation of some of them. Noti7 reporter Anibal Archila, one of the first to cover the event, was reportedly killed by volcanic debris.

In its recent history though, Katla has been less active as the last major eruption occurred in 1918. These eruptions have had a Volcanic Explosivity Index (VEI) of between 4 and 5 on a scale of 0 to 8. In comparison, the Eyjafjallajökull 2010 eruption had a VEI of 4. Larger VEI-5 eruptions are comparable to Mount St. Helens 1980 eruption ...
