She mentioned the volcano in 2002 measured 4, a “massive” volcano on the Volcanic Explosivity Index, a scale used to measure the energy of an eruption by a number of components, resembling period, ash quantity and plume top. Mount Pinatubo within the Philippines in 1991 measured 6 on the index. Mount St. Helens in america in 1980 measured 5.
