The VEI (Volcano Explosivity Index) rates volcanic eruptions based on the volume of ejected material, the height of the eruption plume, and the time duration of the event. The scale runs from 0 (low volume, non-explosive lava flow) to 8 (mega-colossal volcanic explosion, accompanied by seismic events and/or tsunamis). E.g. Mount St. Helens, 1980, had a VEI of 5. Mount Mazama (an exploded volcano that now forms Crater Lake) erupting around 5600 BC, had a VEI of 7.

Volcanoes are measured on the volcano explosivity index. See the link below for more information.
What is the magnitude of nevado del ruiz volcano?
The Richter scale is applied to earthquakes, not volcanoes. The 1985 eruption was a VEI 3 on the Volcanic Explosivity Index.
What is the Volcanic Explosivity Index of Eldfell?
The Volcanic Explosivity Index (VEI) of Eldfell volcano, located on Heimaey Island in Iceland, is estimated to be 2. Eldfell last erupted in 1973, producing a moderate-sized explosive eruption that resulted in the evacuation of the island's inhabitants.
How do scientists classify volcano eruptions?
Volcanic eruptions are classified on the Volcanic Explosivity index, which is based on parameters such as the amount of material erupted and the height of the eruption column.
What is the eruption violence of Santorini volcano?

What would you use to measure the magnitude of an volcano?
One commonly used metric to measure the magnitude of a volcano is the Volcanic Explosivity Index (VEI), which quantifies the explosiveness of volcanic eruptions based on factors like volume of erupted material and height of eruption column. Other measures include seismic activity, gas emissions, and ground deformation monitoring to assess volcanic activity levels.
What type of volcano is Mt Toba?
Mt. Toba is a supervolcano, which is a type of volcano capable of producing massive eruptions with a Volcanic Explosivity Index (VEI) of 8, the highest level. These types of eruptions are thousands of times more powerful than typical volcanic eruptions.
How do volcanologists tell the difference between an extinct volcano and a dormant one?
explosivity

How violent can a volcano get?
Very. The reports of the blast in which Kraktoa was destroyed are almost beyond belief. And there were larger volcanic blasts in the distant past. Krakatoa was a 6 on the Volcanic Explosivity Index while Tambora was a 7. Need links? You got 'em.
What was the magnitude of the mt st Helens eruption in 1980?
Wikipedia lists its explosive index as 5. Read below for more details about the Volcanic Explosivity Index.
