Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
An eruption on April 11 ejected a cloud of volcanic gas and ash that reached a height of 20 km (12 mi) and spread over an area of 108,000 km 2 (42,000 sq mi). [10] Pyroclastic flows from the eruption traveled up to 19 km (12 mi) away from the volcano. [11] 3 Bezymianny [12] Russia 2022 15
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 ...
The inability to create reliable eruption forecasts owes largely to the fact that volcano systems are so varied. The way one volcano comes to life is not necessarily how others around the world ...

The next biggest supereruption formed the Yellowstone Caldera (640,000 years ago) and produced the Lava Creek Tuff. The Yellowstone Supervolcano also produced one additional smaller eruption, thereby creating the West Thumb of Yellowstone Lake [64] 174,000 years ago.
RELATED: Yellowstone supervolcano. The last super-eruption occurred much quicker than originally thought. A researcher from Arizona State University, Hannah Shamloo, said: “It’s shocking how ...
