Video of bison fleeing Yellowstone National Park in Wyoming has sparked rumors that the animals sensed the recent earthquake or an impending eruption of the supervolcano on which the park sits.
Yellowstone was rattled Sunday by a 4.7 magnitude quake.
The first stampede video was posted online a week and half earlier.
What’s worse, an eruption of the supervolcano would have a force 10 times greater than that of Mount St. Helens. Supervolcanos produce ejecta with a force thousands times larger than a normal volcano.
But the head of the Yellowstone Volcano Observatory says the bison aren’t fleeing, they’re just running, like they “do every day.”
The animals migrate to forage, whether or not there’s a quake.
"Those bison are running because that's what they do every day in Yellowstone. This is the time of the year when bison naturally migrate in and out through the park," said YVO scientist-in-charge Jake Lowenstern.
In fact, the bison in the video were running towards the supervolcano.
"I know exactly where those bison were headed because it's about 100 yards from my house. They were headed back into the park," said Lowenstern.
"We don't anticipate an eruption anytime soon," Lowenstern said, adding "We don't find this very convincing new evidence."
"Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years," the University of Utah Seismograph Stations said in a release.
The eruption of the supervolcano would be a showstopper.
"It would be a global event," Jamie Farrell of the University of Utah told The Associated Press last year. "There would be a lot of destruction and a lot of impacts around the globe."
Apparently, if you want a predictor of seismic activity, look no further than the Redwood ant. These ants build on fault lines and move out of their mounds before any quake measuring 2.0 and higher.
