900+ earthquakes shake Yellowstone in 2 weeks

National park shaking amid large earthquake swarm

SALT LAKE CITY, Utah (ABC4 Utah) Yellowstone National Park is experiencing the largest earthquake swarm since 2010. 

University of Utah Seismograph Stations recorded more than 900 earthquakes since June 12. 


More than 120 people reported feeling a magnitude 4.4 quake on June 15, the largest in the swarm. 

Average swarms consist of a few dozen earthquakes over a couple days, according to Jamie Farrell, U of U professor studying seismic activity in the country's first national park. 

"When it gets to these bigger ones, we pay attention to them just because we need to monitor these things just in case something changes," Farrell said. 

Farrell believes the activity is caused by stress building up under the crust of the massive volcano. He says there is no reason to panic along the Wasatch Front.

"This is an active volcano. This is what happens. We get a lot of calls asking if they should cancel their trip to Yellowstone. Definitely no. I would say even the opposite of that. Go there and maybe you'll feel an earthquake. It would be kind of neat," said Farrell.
