The Supervolcano beneath Yellowstone is 2.5 times bigger than ever expected. After measuring the magma in Yellowstone’s supervolcano, scientists found that an eruption would be 2,000 times the size of the 1980 eruption of Mount St. Helens. “Scientists are reporting that the supervolcano lying beneath Yellowstone National Park in the US is far bigger than was previously thought, stretching for more than 90km (55 miles),” reported BBC on Dec. 11, 2013.
An eruption of the supervolcano beneath Yellowstone would shoot up so much material into the earth that it could destroy the whole country and cause worldwide chaos.
In his recent interview with BBC, Dr. James Farrell from the University of Utah said that the unexpected size of the supervolcano beneath Yellowstone was discovered by recording seismic activity caused by the active volcano.
“We’ve been working there for a long time, and we’ve always thought it would be bigger ... but this finding is astounding,” said Professor Bob Smith, from the University of Utah.
The new “astounding” discovery about the tremendous size of the supervolcano beneath Yellowstone National Park is being presented at the American Geophysical Union meeting in San Francisco this week and describes Yellowstone’s supervolcano to have depths of up to nine miles – stretching 55 miles across and 30 miles wide.
If an eruption of Yellowstone’s supervolcano did take place, it would be a catastrophic event and “it would affect the world," said Dr. James Farrell.The amount of ashes that would enter the atmosphere could potentially be a major catastrophic climate change that goes beyond anyone's imagination.
Since the last major eruption of a supervolcano happened over 640,000 years ago, scientists do not expect an eruption of the supervolcano beneath Yellowstone in the near future – but they are keeping a close eye on any seismic activity that would provide a warning that Yellowstone’s supervolcano is warming up to something big.
