Is the world's largest super-volcano set to erupt for the first time in 600,000 years?

Yellowstone National Park, set aside as a national park on March 1, 1872, is located mostly in the U.S. state of Wyoming, though it also extends into Montana and Idaho.


July 22, 1980: Mount St Helens in Washington erupts. A Yellowstone caldera eruption would explode with a force a thousand times more powerful


The super-volcano beneath Yellowstone National Park in Wyoming has been rising at a record rate since 2004

It would explode with a force a thousand times more powerful than the Mount St Helens eruption in 1980.
Spewing lava far into the sky, a cloud of plant-killing ash would fan out and dump a layer 10ft deep up to 1,000 miles away.
