Yellowstone's supervolcano may erupt sooner than expected
Oct 13 2017 by Michele Stevens
A supervolcano now lies dormant underneath the Yellowstone National Park, but once it prepares for its next eruption, we will not have much time to prepare for the disastrous event.
The odds of any supervolcano erupting in the near future remain small, the researchers say - but the forces that drive these rare events may move faster than anyone thought.
Unsettling new research shows it could take only decades for the giant Yellowstone volcano to reawaken, plunging the world into a volcanic winter and potentially destroying all humanity. The crystals also reveal a supereruption followed much quicker than scientists previously thought-perhaps within decades, or what Popular Mechanics calls "a geologic snap of the finger". And a study in 2013 showed that the volume of magma moving into the supervolcano is almost three times larger than previously thought.
A study co-author and student from the Arizona State University, Hannah Shamloo stated that, "It's shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption".
Yet a massive eruption in the middle of the U.S.is still an unlikely event.
Yellowstone's last super-eruption happened 631,000 years ago. A variety of sensors and satellites are always looking for changes, and right now, the supervolcano does not seem to pose a threat. The only change apparent with this research is our understanding of pre-eruption dynamics.
