A supervolcano beneath Yellowstone National Park in Wyoming was extremely underestimated in size after its discovery by researchers. Epoch Times reported Dec. 13 that the marvel is about two-and-a-half times larger than originally recorded.
The massive Yellowstone volcano has a cavern spanning 55 miles.
A team of scientists took a second look at the supervolcano beneath Yellowstone and learned this startling find. The team comprised of Bob Smith and Dr. Jamie Farrell from University of Utah. They announced their findings at the American Geophysical Union’s fall meeting in San Francisco on December 13.
“We’ve been working there for a long time, and we’ve always thought it would be bigger… but this finding is astounding,” Smith said.
The supervolcano beneath Yellowstone is believed to do extreme damage when it blows up. The last major eruption was known to take place about 640,000 years ago. It resulted in ash covering all of North America. Volcanoes are known to erupt every 700,000 years, but Smith said more data needs to support that theory. If this Yellowstone volcano erupts, it's believed to harm the entire planet and possibly wipe out all mankind.
Seisometers were used to study the supervolcano.
“We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground,” said Dr. Farrell.
“The waves travel slower through hot and partially molten material… with this, we can measure what’s beneath.”
The last large eruptions happened 2.1 million years ago and 1.3 million years ago. Will the supervolcano beneath Yellowstone be just as devastating?
