What is mount Pinatubos vei?
Mount Pinatubo's eruption in 1991 had a Volcanic Explosivity Index (VEI) of 6. This scale measures the magnitude of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of eruption. A VEI 6 is classified as a "colossal" eruption.
What is a VEI scale?
The Volcanic Explosivity Index (VEI) is a scale used to measure the explosiveness of volcanic eruptions. It ranges from 0 to 8, with higher numbers corresponding to larger eruptions. The scale takes into account factors such as volume of erupted materials, height of eruption column, and duration of the eruption.
