volcanic explosivity index
- (VEI)a measure of the severity of a volcanic eruption. The VEI scale is from 0 to 8; an index value of v corresponds to an output of at least 103+v cubic meters of magma. The Mt. St. Helens eruption of 1980 was a 5 on this scale, and the largest eruption of historic times (the Tambora eruption of 1815) rated a 7. A table is provided.
