Supervolcano is the title of a British-Canadian television disaster film, first released in 2005. It tells a fictional story of a supereruption at Yellowstone.

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.

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...

Feb 11, 2024 · Supervolcanoes are the largest, most explosive, and catastrophic volcanic eruptions. They spew immense volumes of at least 1000 km 3 of ash, gas, and other debris and have a volcanic explosivity index of 8. These eruptions are ultraplinian and produce large ash plumes reaching the stratosphere.

Something volcanic is stirring close to the Italian city of Naples and it has nothing to do with the looming presence of Mount Vesuvius. Another volcano lurks close by, one that’s much harder to spot, but potentially far more dangerous than its neighbouring cousin. And it’s getting restive.

A volcano is categorised as a supervolcano if it can produce a magnitude-eight eruption on the Volcanic Explosivity Index, discharging more than 1,000 cubic kilometres of material. These eruptions are sometimes called 'super eruptions' and are the biggest and most explosive of all.

Volcanoes that have produced exceedingly voluminous pyroclastic eruptions and formed large calderas in the past 2 million years include Yellowstone in northwest Wyoming, Long Valley in eastern California, Toba in Indonesia, and Taupo in New Zealand.

Jul 1, 2017 · Supervolcanoes are volcanic centers that have experienced the eruptions ranked at level 8 on the Volcanic Explosivity Index (VEI). The VEI is a scale that describes the size of volcanic eruptions based on magnitude and intensity. It is a numerical scale (from 0 to 8) on a logarithmic basis that is generally analogous to earthquake magnitude scales.

The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning the measured deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles).
