relative measure of explosive volcanic eruption size (based on product volume, eruption cloud height, etc.), open-ended with the biggest prehistoric eruptions given magnitude 8
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.
