Is The World's Largest Super-Volcano Set To Erupt For The First Time In 600,000 Years, Wiping Out Two-Thirds Of The U.S.? -- The Daily Mail

• 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.
Two-thirds of the U.S. could become uninhabitable as toxic air sweeps through it, grounding thousands of flights and forcing millions to leave their homes.

On the verge of a catastrophe? Yellowstone National Park's caldera has erupted three times in the last 2.1million years and scientists monitoring it say we could be in for another eruption (file picture)

This is the nightmare that scientists are predicting could happen if the world’s largest super-volcano erupts for the first time in 600,000 years, as it could do in the near future.
