A 4.8-magnitude earthquake rumbled through Yellowstone National Park early Sunday morning, the area's strongest seismic activity in 34 years.
The quake occurred at 6:34 AM local time and originated near the Norris Geyser Basin in northwest Wyoming, approximately 23 miles outside of West Yellowstone, Montana. There were no reports of injuries or damage.
In a statement, the University of Utah Seismograph Station said that the large tremor is the latest in a series of 25 quakes that began last Thursday. The agency also stressed that such flurries, known as "earthquake swarms," are not unusual. The Yellowstone region is one of the world's largest active geothermal areas and sees an average of 1,600 small quakes per year.
