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).
What is a supereruption? 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.

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.
Nov 10, 2023 · What does it mean to be a supervolcano? “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 ...

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.
