The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material.
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles).
Jun 10, 2023 · The explosion of Mount Tambora is the l argest ever recorded by humans, ranking a 7 (or "super-colossal") on the VEI, the second-highest rating in the index. The volcano, which is still...
Dec 7, 2023 · A supervolcano is a volcano that has produced at least one supereruption, meaning that at some point in its history, it has ejected more than 240 cubic miles (1,000 cubic kilometers) of...
These eruptions are sometimes called 'super eruptions' and are the biggest and most explosive of all. Before an eruption, magma collects in a chamber below the surface and pressure builds until the magma eventually ruptures Earth's crust.
Mar 19, 2019 · According to the United States Geological Survey, a volcano is considered “super” if it has had at least one explosion that released more than 240 cubic miles of material—a little more than twice...
May 17, 2023 · What are super-eruptions? The Huckleberry Ridge Tuff and Lava Creek events are considered super-eruptions because they expelled over 240 cubic miles (1,000 cubic kilometers) of material....
May 19, 2023 · The last super-eruption at Yellowstone volcano, which occurred 631,000 years ago, was not one huge explosion. Instead, new research suggests it was a series of eruptions or multiple vents...
Nov 10, 2023 · “When a volcano is called a supervolcano, what we really mean is it had a super eruption once, at least, in the past,” said Christopher Kilburn, a volcanologist at University College London.
The docudrama Supervolcano dramatically explores the impact of a large caldera-forming eruption at Yellowstone. The scale of the portrayed eruption is similar to the eruption of the Huckleberry Ridge Tuff at Yellowstone 2.1 million years ago.
