The Global Volcanism Program has assigned a Volcanic Explosivity Index ( VEI ) to all except five of K + lauea's ninety-five known eruptions of the last 11, 700 years.
42.
Individual eruptions were often enormous, sometimes up to thousands of cubic kilometres in volume, giving them a Volcanic Explosivity Index of 8, comparable to Yellowstone Caldera and Lake Toba eruptions.
43.
All of the eruptions listed below have produced at least of lava and tephra; for explosive eruptions, this corresponds to a Volcanic Explosivity Index ( or VEI ) of 8.
44.
In 1477, the largest known eruption from B�r�arbunga had a volcanic explosivity index ( VEI ) of 6; there is evidence of many smaller eruptions during the past 10, 000 years.
45.
Since AD 1000, Kelud has erupted more than 30 times, of which the largest eruption was at scale 5 on the Volcanic Explosivity Index, while Merapi has erupted more than 80 times.
46.
The last major eruption on Galunggung was in 1982, which had a Volcanic Explosivity Index of 4 and killed 18 people ( due to indirect cause ( traffic accident, starvation ) ).
47.
Measured in terms of explosivity on what's called the " Volcanic Explosivity Index, " the May 18, 1980 eruption that killed 57 people came in at a " 5 " on the 8-point scale.
48.
About 5, 000 years ago, the largest volcanic eruption of the Central Andes with a volcanic explosivity index of 7 occurred at Cerro Blanco, forming the most recent caldera as well as thick ignimbrite layers.
49.
One explosive eruption about 4, 700 years ago may have had a VEI ( Volcanic Explosivity Index ) of 5, which is the same as the 18 May 1980 eruption of Mount St . Helens.
50.
Since AD 1000, Kelut has erupted more than 30 times, of which the largest eruption was at scale 5 on the Volcanic Explosivity Index ( VEI ), while Mount Merapi has erupted more than 80 times.
