Yellowstone supervolcano could blow faster than initially thought

(FOX News) -- Arizona State University researchers have analyzed minerals around the supervolcano at Yellowstone National Park and have come to a startling conclusion. It could blow much faster than previously expected, though any talk of it potentially wiping out life as we know it is incorrect.

According to National Geographic, the researchers, Hannah Shamloo and Christy Till, analyzed minerals in fossilized ash from the most recent eruption. What they discovered surprised them – the changes in temperature and composition only took a few decades, much faster than the centuries previously thought.

“We expected that there might be processes happening over thousands of years preceding the eruption,” said Till said in an interview with the New York Times.

Despite some sensationalist claims seen in the media, the supervolcano is not expected to erupt anytime soon and if it did, the events would not be catastrophic. "There's no reason to think it could impact mass transport the way the Iceland eruption did nor would it have any effect on crops," Till told Fox News. "There is no evidence to suggest it could destroy mankind."

The supervolcano last had a major eruption about 630,000 years ago, Till added. Prior to that, the last major eruption was 1.3 million years ago, per a report from ZME Science. A smaller eruption, the most current on record, occurred 70,000 years ago.
