The loosely defined term "supervolcano" has been used to describe volcanic fields that produce exceptionally large volcanic eruptions. Thus defined, the Yellowstone Supervolcano is the volcanic field that produced the latest three supereruptions from the Yellowstone hotspot; it also produced one additional smaller eruption, thereby creating the ...
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions. [3]
This eruption is considered the climactic event of Yellowstone's third volcanic cycle. The Lava Creek Tuff covers an area of more than 7,500 km 2 (2,900 sq mi) centered around the caldera and has an estimated magma volume of 1,000 km 3 (240 cu mi).
Beneath the ground of Yellowstone National Park lies a monster volcano that had its last super-eruption over 630,000 years ago and it could erupt again.
The most recent volcanic eruption occurred in Yellowstone approximately 650,000 years ago resulting in a 30- by 45-mile caldera, or basin. The heat powering the volcanic eruptions still fuels the ...
Scientists working in Yellowstone National Park say the supervolvcano underneath may blow sooner than thought and could wipe out life on the planet. Yellowstone supervolcano may be only decades ...

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. Numbers indicate millions of years before ...
