A supervolcano beneath Yellowstone is a new threat that is quite a bit bigger than experts expected earlier. This huge supervolcano has been revealed through a breaking study to possess a magma chamber that is nearly three times as large than formerly anticipated, spanning over 55 miles and holding an immense amount of molten rock, RawStory shares this Friday, Dec. 13, 2013.
The supervolcano beneath Yellowstone isn’t something most civilians worry about on a daily basis, but it could pose a real threat to the U.S. people. With an inner cavern that huge, it’s been called by experts a truly astounding discovery.
“We’ve been working there for a long time, and we’ve always thought it would be bigger,” said Bob Smith, University of Utah professor. “But this finding is astounding.”
“We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground,” said Dr. Jamie Farrell, of the University of Utah. “The waves travel slower through hot and partially molten material (and) with this, we can measure what’s beneath.”
A supervolcano hasn’t erupted for hundreds of thousands of years, and that’s a very good thing. This “new” threat, like the danger sitting quietly under Yellowstone National Park and filled with molten magma, permeated through North America with heat and ash, making severe changes in the entire world’s climate. Having a similar eruption in today’s day and age could mean devastation for earth once again.
“To our knowledge there has been nothing mapped of that size before,” the professor added.
Fortunately, there has been no significant activity hailing from the supervolcano beneath Yellowstone National Park, but this is nonetheless something that experts should be keeping a very close eye on, concludes the report. However, with eruptions happening every 700,000 years, and the last apparently occurring over 620,000 years ago, it's possible that the next huge incident isn't as far off as we might hope.
