Numerous reports and videos (like this one) of bison and other animals fleeing have been circulating since the March 30 earthquake in Yellowstone National Park. Although scientists can’t predict when the Yellowstone supervolcano will erupt, a lot of people think that’s why the bison are “running for their lives” as one video describes it.
But the University of Utah Seismograph Stations say we need not worry:
“There is no evidence that a catastrophic eruption at Yellowstone National Park (YNP) is imminent,” the service said. “Current geologic activity at Yellowstone has remained relatively constant since earth scientists first started monitoring some 30 years ago. Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years.”
Definitive reason or not, it’s an incredible sight.
