The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.
The reddish sky in the background is the artist's memory of the effects of the powerful volcanic eruption of Krakatoa, which deeply tinted sunset skies red in parts of the Western hemisphere for months during 1883 and 1884, about a decade before Munch painted The Scream.
With an estimated Volcanic Explosivity Index (VEI) of 6, [2] the eruption was equivalent to 200 megatons of TNT (840 PJ)—about 13,000 times the nuclear yield of the Little Boy bomb (13 to 16 kt) that devastated Hiroshima, Japan, during World War II, and four times the yield of Tsar Bomba, the most powerful nuclear device ever detonated at 50 Mt.
This article is a list of historical volcanic eruptions of approximately magnitude 6 or more on the Volcanic Explosivity Index (VEI) or equivalent sulfur dioxide emission during the Holocene, and Pleistocene eruptions of the Decade Volcanoes (Avachinsky–Koryaksky, Kamchatka; Colima, Trans-Mexican Volcanic Belt; Mount Etna, Sicily; Galeras ...
This is a list of notable volcanic eruptions in the 16th to 20th centuries with a Volcanic explosivity index (VEI) of 4 or higher, and smaller eruptions that resulted in significant damage or fatalities. Note that there may be uncertainties to dates with historical eruptions, and there are likely to be many large eruptions that have not been ...
A supervolcano is one that has ejected more than 240 cubic miles of material and reached a level 8 — the highest threat — on the Volcano Explosivity Index or VEI, according to the US ...
Satellite images of the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai. This is a list of volcanoes that have had large explosive eruptions during the Holocene (since about 11,650 years Before Present), with a volcanic explosivity index (VEI) of 5 or higher, or a plume height of at least 30 km.
Technically, there's no official definition for a supervolcano structure other than it being capable of eruptions of at least a seven on the volcanic explosivity index. A volcanic eruption that ...
