Many are suspecting the worse when recalling that animals are often said to have a kind of sixth sense for disaster. They flee when something is about to occur.
With the recent 4.8 magnitude earthquake in the vicinity of the super volcano in Yellowstone National Park, many have been on edge about a possible eruption of one of the biggest volcanoes on our planet.
Others are wondering if the Bison are trying to tell us something.
A visitor to Yellowstone National Park caught a stampede on camera, and now it has people wondering: Is the Yellowstone caldera is about to blow?
If it were to erupt, the effects would be disastrous.
According to Yellowstone spokesman Dan Hottle, “Those bison are running because that’s what they do every day in Yellowstone.”
And Al Nash, another spokesman for Yellowstone National Park, said: "We have heard about some pretty wild rumors - including one concerning the animals.
"We do have bison, elk and other animals that have moved outside the park recently, but they're doing that because we're in the depths of winter and food is a little hard to find in places.
"At this time of year, they tend to migrate to lower elevations where they think there might be something to eat that's easier to get at. When the snow melts off and things start to green up, those very same animals will walk right back into the park."
According to the US Geological Service (USGS), there has been an uplift in earthquake activity around Yellowstone's caldera.
The super volcano last erupted 70,000 years ago and another one is likely to deposit huge quantities of ash across much of the country.
Nash said there were "no signs" tectonic activity was about to cause Yellowstone's volcano to erupt.
"We see between 1,000 and 3,000 earthquakes a year in Yellowstone and most of them are so small no one ever feels them," he said.
Adding, "we've had this recent earthquake near the Norris geyser basin, but there were no injuries or damage and ... it's just part of the geology of Yellowstone."
