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). [2] Location of Yellowstone hotspot over time.
Michael Poland, a geophysicist at the U.S. Geological Survey and the scientist-in-charge of the Yellowstone Volcano Observatory, said that while Campi Flegrei and Long Valley are capable of huge ...
The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred around 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment. “The western part of the Yellowstone ...
It is 22 by 47 miles (35 by 75 km) and oblong in shape. Many calderas of explosive origin are slightly ovoid or oblong in shape. Because of the vast scale and erosion, it took scientists over 30 years to fully determine the size of the caldera. La Garita is considered an extinct volcano.
An iconic volcano is an exploding mountain — think Vesuvius or Washington's Mount Saint Helens, which erupted in 1980 — but supervolcanoes typically look unassuming. Campi Flegrei, or the ...
This category collects volcanoes popularly known as supervolcanoes.Supervolcanoes are large volcanoes that have had an eruption with a volcanic explosivity index (VEI) of 8, the largest recorded value on the index.
A long-quiet yet massive super volcano, dubbed the "Long Valley Caldera," has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so.
