Bloggers have pointed to video of bison and other animals seen fleeing Yellowstone National Park near the time of a 4.8-magnitude earthquake as cause concern of an impending super volcano.
Sunday's earthquake was the biggest recorded at Yellowstone since February 1980.
The park sits atop one of the world's largest super-volcanoes, but so far there was no indication the seismic activity was related to an eruption.
However, bloggers said visitors to the park recorded animals leaving the park around the time of the earthquake, according to The Epoch Times
, and could be an early indication of something bigger coming.
"Biologists aren't sure if there's been a stunning decline in the herd or if other factors have skewed the tally," Tom Lupshu, a self-described survivalist said on YouTube.com
. "Herds of bison running for their lives on the public roadways and they were not being chased or rounded up, the bison were running down the mountain slopes onto roadways running right past a filming crew. They detect something vast and deadly. The Yellowstone super volcano is the only thing there that would fit the bill."

Yellowstone National Park public affairs head Al Nash told Buzzfeed.com
that the bison movement was not out of the ordinary and caused by the prolonged winter at the park. Nash added that the animals look for food at lower elevations and return in the spring.
"We have seen no signs to suggest the Yellowstone volcano is about to erupt," said Nash about the bison's comings and goings.
The super volcano that sits under Yellowstone has not erupted in 650,000 years. Jenni McDermott, a geologist at St. Thomas University, told KMSP-TV
it would be difficult to predict if or when it would erupt again.
"Given the life span of the average human, we don't really have anything to worry about," said McDermott, adding it could be another 1,000 years before there is a serious threat of a new super volcano in the area.
"We see a little activity, and then a lot more, and then a lot more, and then a lot more, and then we'll see an eruption," McDermott told the television station.
A Yellowstone super volcano could erupt with the force equivalent to 10,000 eruptions of Mount St. Helens.
