Videos of bison seemingly fleeing from Yellowstone National Park in Wyoming have a growing number of people on the web wondering if the great animals may sense a volcanic eruption is not far off and are trying to leave the area.

Or, as a Park Service video made in response to the chatter suggests, they may just be hungry.

Within the past few days, videos of animals leaving the park have begun to surface on YouTube, and people who describe themselves as naturalists or survivalists have suggested on blogs that the recent seismic activity in the area is a sign that an eruption of the so-called Yellowstone Supervolcano is imminent.

The Yellowstone Supervolcano, according to the U.S. Geologic Survey, is a volcanic field that has produced at least three super eruptions (massive volcanic eruptions that vaporize thousands of square miles in a matter of seconds) from the Yellowstone hotspot -- the oldest one thought to have happened 2.1 million years ago.

Perhaps sparking some of the theories, the Park Service video suggests, is a magnitude 4.8 quake that struck last week in the park. While it was the largest to hit the area in 30 years, it caused no damage. Quakes, the video points out, are common in the park.

According to Epoch Times, the University of Utah Seismograph Stations also downplayed fears.

"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."
