1,000 times more powerful than Mt. St. Helens.

Ash 10 ft. deep would cover the ground for up to 1,000 miles away.

2/3’s of the U.S.A. would become uninhabitable due to toxic gasses.

Air travel would stop across the U.S.A. Millions of people would be homeless. Assignment Discovery Shorts: Yellowstone?s
