It has produced three caldera-forming eruptions in the past 3 million years: the Huckleberry Ridge Tuff eruption, 2.1 million years ago; the Mesa Falls eruption, 1.3 million years ago; and the ...

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Christy Till, assistant professor ...

The last caldera-forming eruption at Yellowstone "was much more complex than previously thought," according to the annual report about activity at the supervolcano. The last super-eruption at ...

Mantle plumes were the implicit link in previous studies relating BLOBS to giant volcanic eruptions. Their shape is a bit ...

Yellowstone had massive eruptions 2.1 million years ago, 1.3 million years ago, and 640,000 years ago, as well as several smaller ones. An eruption in the near future would fit the timeline.

The last super-eruption at Yellowstone volcano, which occurred 631,000 years ago, was not one huge explosion. Instead, new research suggests it was a series of eruptions or multiple vents spewing ...

The three eruptions at Yellowstone during the past 2 million years were, respectively, 2,500, 280, and 1,000 times larger than the 1980 Mount St. Helens eruption.

In geology, even small layers can tell big stories. But figuring out the origins of such small layers can be a challenge, ...

Past methods employed to probe the volcanic ... of magma released roughly 1.3 million years ago during the Mesa Falls eruption—the second most recent caldera-forming eruption at Yellowstone.

“Nowhere in Yellowstone do we have regions that are capable of eruption,” the magma maven explained. In other words, it will not be an issue during our lifetime.

The Yellowstone supervolcano, located in northwestern Wyoming, has experienced three giant explosions in the past two million years or so, which were among the largest eruptions known to man.
