Yellowstone supervolcano eruption 2015: How much damage it can cause if it erupts?
Yellowstone National Park is the biggest supervolcano in the world. Though many claimed earlier that the Yellowstone National Park supervolcano was dormant, but it has come to the notice it is not the case and that the supervolcano is active.
One more aspect that has created more anxiety among scientists is the fact that the supervolcano is far bigger than previously thought. University of Utah scientists who have been studying the Yellowstone supervolcano created a flutter of sorts when they discovered a massive reservoir beneath the old one. They claim the new reservoir is bigger than anything that they had seen or expected.
According to the University of Utah scientists who have been undertaking study about one of the biggest known supervolcanoes in the world, the newly found reservoir is actually made up of magma which is around 30 miles long, 44 miles wide, 12 miles deep, and ending 28 miles below the deepness.
A noted volcanologist and assistant professor with the Department of Geosciences at Idaho State University Dr. Shannon Kobs Nawotniak says â€œNobody has ever seen a supervolcano erupt, and thereâ€™s never been any human documentation of an event like this occurringâ€¦The last eruption at Yellowstone occurred long before humans came to North America.â€
Though there is no fear of immediate eruption here at the moment, scientists have been talking about the possible impact of the eruption. Dr Bob Smith believes a supervolcano eruption under Yellowstone would cover the western U.S with ash that would also enter the jet stream potentially crippling air travel and the worldâ€™s food supply.
While talking about it, Bob Smith says, â€œThe actual hazard is the same, but now we have a much better understanding of the complete crustal magma system,â€ says he. Researchers are of the opinion that the overwhelming bulk of their magma cavities comprise scorching â€” yet solid â€” rock, which is hollow, like sponges, and filled with pockets of liquefied rock. An eruption in the next few thousand years is extremely unlikely, the USGS says. The Utah scientists put the yearly chance at 1 in 700,000 â€” about the odds that you will be struck by lightning. Nonetheless despite the low chance of eruption, it remains the most talked about issue among seismologists and others in the US.
