Yellowstone supervolcano massive in size: Force to be reckoned with if it blows

The Yellowstone supervolcano which sits beneath Yellowstone National Park is much bigger in size than anyone could have imagined. The new measurements of the Yellowstone supervolcano are bigger than first thought, this volcano stretches 55 miles and holds 200 to 600 cubic kilometers of molten rock, according to Raw Story on Dec. 13.

The supervolcano hidden beneath Yellowstone is “astounding” in size, said Bob Smith, University of Utah Professor. The latest findings were presented at the American Geophysical Union Fall Meeting in San Francisco and it has caught the attention of scientists globally.

An eruption today would be catastrophic to the planet, much like the last major eruption at Yellowstone. It was 640,000 years ago when the supervolcano erupted and effected the climate of the entire planet, covering all of North America with ash.

According to Jamie Farrell from the University of Utah, to the best of the researchers’ knowledge, there has been nothing mapped of this size ever before. The magna chamber, which holds the mixture of solid and molten rock, goes out much further to the east than previously thought.

Researchers can’t say when an eruption of this supervolcano might happen again, so the new findings doesn’t necessarily make the Yellowstone volcano more of a risk than it was before. Knowing the size of the dormant monster beneath this national park means that if it does blow, it will be a force to be reckoned with.
