Best Answer

The Volcanic Explosivity Index (VEI) is a measure of the explosiveness of volcanic eruptions. It was devised by Chris Newhall of the United States Geological Survey and Stephen Self at the University of Hawaii in 1982. The index is based on a scale of 1 to 8, 1 being very small, and 8 being huge and very rare.

Volcanoes are measure by their height, as most form mountains. Volcanic eruptions are often measure by the amount of material that comes out during an eruption.
