The Volcanic Explosivity Index (commonly shortened to VEI) is a scale, from 0 to 8, for measuring the strength of eruptions. 2020 Eruption of Mount Vesuvius (FrigidusMedicane) 2010 Eruption of Mount Everest; 2040 Mount Wilshire Eruption; 2024 Mount Doom Eruption; 5285 eruption of Long Valley Caldera; 2019 eruption of Mt Vesuvius; 2295 Moscow eruption The VEI scale "only" reaches up to 8, which describes cataclysmic eruptions. The eruption was estimated Volcanic Explosivity Index (VEI) of 6, which was equivalent to 200 megatons of TNT or about 13,000 times the nuclear blast which destroyed Hiroshima, Japan. Wikimedia Commons has media related to VEI-6 volcanoes. It buried the surrounding region in 6.6 feet of rock, destroying all vegetation. There are around 10 – 14 VEI 5+ eruptions every hundred years and for the last 300 years the time between eruptions has been as short as 1 year and as long as 23 years. Huaynaputina likely contributed to the Little Ice Age that began around this time, leading to floods, famines, and political upheavals all … That means the large eruption, like a VEI 6 such as the Pinatubo eruption in 1991, erupted over 10 km3 of material. A value of 0 is given for non-explosive eruptions, defined as less than 10,000 m3 (350,000 cu ft) of tephra ejected; and 8 representing a mega-colossal explosive eruption that can eject 1.0×1012 m3 (240 cubic miles) of tephra and have a cloud column height of over 20 km (66,000 ft). The explosion of Huaynaputina in 1600 is one of the biggest volcanic eruptions in the history of South America. VEI has logarithmical increases. Volume of Material Ejected: 160 km³ (38 cu mi) Estimated Number of Victims: Unknown… This video was originally published 27/8/2019 . We live in a globalized world. +1 on the VEI scale means an eruption ten times more powerful. The Volcanic Explosivity Index is a relative measure of the explosiveness of volcanic eruptions.It was devised by Chris Newhall of the United States Geological … Fortunately, none of the planes that inadvertently flew into it lost power, but some required engine replacements and other costly repairs. In contrast to the VEI-5 eruption of Mount St Helens in 1980, or to the VEI-6 eruption of Mount Pinatubo in the Philippines in 1991, a VEI-7 eruption would be of an entirely different scale and in a totally different environment. Geologists estimate plant life and animals up to 37 miles from the blast were exterminated - a result of the eruption reaching a Volcanic Explosivity Index (VEI) of 6. Volume of products, eruption cloud height, and qualitative observations (using terms ranging from "gentle" to "mega-colossal") are used to determine the explosivity value. Another weakness of the VEI is that it does not take into account the power output of an eruption, which makes the VEI extremely difficult to determine with prehistoric or unobserved eruptions. The last major eruption (size VEI 7) happened in Indonesia in 1815 and several more eruptions … Etna eruption was rated a 3+. By 2010, the Global Volcanism Program of the Smithsonian Institution had catalogued the assignment of a VEI for 7,742 volcanic eruptions that occurred during the Holocene (the last 11,700 years) which account for about 75% of the total known eruptions during the Holocene. The Volcanic Explosivity Index (VEI) is a relative measure of the explosiveness of volcanic eruptions. This list may not reflect recent changes (learn more). The Krakatoa Eruption was a VEI 6 eruption that destroyed most of the island of Krakatoa and created the loudest sound in recoded history, loud enough that it could be heard 3,000 miles away, and was picked up by barometers all around the globe. Along the way are a few intermediate grades and four different Plinian types. The last VEI 5 level eruption was in 1991 and a major eruption of intensity 5 or greater is now overdue. Category:VEI-6 volcanoes. I thought the corporate media would jump on this story and blame it on global warming, but they did not. Under the VEI, ash, lava, lava bombs, and ignimbrite are all treated alike. It was the largest eruption in El Salvador during the past 10,000 years and one of the largest in Central America. It has been almost 30 years since the last VEI 5+ (Mount Pinatubo, 1991, VEI 6) occurred and the probability that a VEI 5+ volcanic eruption will occur within the next 5 years is now over 95%. This follows a common pattern for most caldera complexes. Eruptions of VEI 7 of the past 10 k.y., and a few that are classed as VEI 6 based on minimum estimates of deposit volume and might later be upgraded to VEI 7, are shown in Table 1. It is used by the Smithsonian Institution's Global Volcanism Program in assessing the impact of historic and prehistoric lava flows.
