Yellowstone is the oldest national park in the world and a popular tourist destination, attracting millions of visitors. National Park has a total area of approximately 9,000 square kilometers.......
The volcano at Yellowstone National Park in Wyoming and Montana sits atop a huge reserve of magma and last erupted 640,000 years ago.
Fears that Yellowstone could erupt are increasing
The massive eruption would be a staggering 2,000 times as powerful as the one from Washington’s Mount St Helens in 1980.
Imagine a circle about 500 miles (800 kilometers) across surrounding Yellowstone.
It said people frequently ask what would happen if Yellowstone erupted and results concluded an event of this kind would leave most of the US covered in a blanket of ash, with some areas buried in over a metre of the dust.
The report, Modeling ash fall distribution from a Yellowstone supereruption, provided simulations of an eruption that lasted three days, one week and one month. All produced 330km of volcanic ash. Findings showed that expansion of the umbrella cloud produced was capable of pushing ash as far as 1,500km.
