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.

In the past 2.1 million years, Yellowstone has had three major eruptions, the most powerful ones in the world’s recorded history and producing enough ash and lava to fill the Grand Canyon.

The supervolcano that lies beneath Yellowstone National Park might have erupted less powerfully but more frequently than previously thought, new research suggests. In the ancient past, the ...

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 ...
