A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, 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).
There are more than 1,000 active volcanoes dotted around our planet, but only a select few have produced unimaginably colossal eruptions, earning themselves the title of supervolcano. Find out more about supervolcanoes - what they are, what their eruptions are like and how they impact our planet.
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...
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.
Nov 1, 2023 · Both volcanoes are calderas — sprawling depressions created long ago by violent “super-eruptions” that essentially collapsed in on themselves — which are often more challenging to forecast...
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...
Sep 3, 2021 · This supervolcano is believed to have erupted roughly 74,000 years ago, and some researchers believe the eruption released six billion tons of sulphur dioxide into the atmosphere, leading global temperatures to plummet by 15C (59F) for three years afterwards.
