Experts have warned that a supervolcano in the heart of America’s northwest at Yellowstone National Park would be 1,000 times more powerful as compare to 1980 Mount St Helens eruption. The supervolcano could made 90,000 immediate deaths and a ‘nuclear winter’ across US.
Scientists said that the spot has inactive for more than 70,000 years but nobody could rejected possibilities of its eruption at any time. However, they said that the chances so far are quite low up to 1 in 700,000 annual changes of its volcanic eruption.
Yellowstone National Park in Wyoming and Montana were circled due to its location on huge reserves of molten rock that had last erupted 640,000 years ago. It is one of the largest active continental silicic volcanic fields in the world. Silicic is used to describe magma or igneous rock rich in silica, Daily Mail reported.
It says that a mixture of magma, rocks, vapour, carbon dioxide and other gases would eventually push out from the ground, creating a dome shape with cracks. The dissolved gases would them explode, releasing the magmaacross the park.
It was also said that the eruption could bring major disaster to the earth that could kill as many as 90,000 people almost instantly and release a 10 ft (3-meter) layer of molten ash 1,000 miles (1,609km) from the park.
Earlier, United States Geological Survey (USGS) study concluded that a volcanic eruption at Yellowstone would cover cities across the country with ash and shut down air travel and communications.
