New research has revealed when Yellowstone's supervolcano will erupt next, as it now contains a higher volume of magma than it's previous three eruptions that formed the caldera ...

The Yellowstone super-volcano is unlikely to erupt anytime soon, according to scientists at the Yellowstone Volcanic Observatory. They’ve determined that current conditions aren't right for a ...

Geologists in Yellowstone National Park spotted a new volcanic feature on the active volcano, evidence of the vibrant geologic activity beneath the surface.

Together, the results allowed them to map out the dimensions of the deeper magma reservoir, 12 to 28 miles beneath the supervolcano.

If that happens, the fallout will be catastrophic. Yellowstone’s volcano is most remarkable because it’s huge, with a rim that measures 30 miles long by 45 miles wide. Technically, it’s not ...
