Yellowstone National Park, which sits atop one of the world's largest super-volcanoes, was struck on Sunday by a magnitude 4.8 earthquake, the biggest recorded there since February 1980, but no damage or injuries were immediately reported.
The tremor, a relatively light event by seismic standards, struck the northwest corner of the park and capped a flurry of smaller quakes at Yellowstone since Thursday, geologists at the University of Utah Seismograph Stations said in a statement.
The latest earthquake struck at 6:34 a.m. near the Norris Geyser Basin and was felt about 23 miles away in two small Montana towns adjacent to year-around entrances to the park - Gardiner and West Yellowstone.
