The Full Story
Volcanic explosivity is commonly measured using the Volcanic Explosivity Index, or VEI, developed by Chris Newhall and Stephen Self in 1982. The scale is logarithmic and uses eruption volume, plume height, and qualitative observations. It helps compare events ranging from small effusive eruptions to colossal explosive blasts like Tambora in 1815. The VEI remains a standard shorthand in volcanology and hazard communication.
