CIRCLEVILLE — A 3.6 magnitude earthquake struck southwestern Utah's Piute County on Tuesday afternoon, a report from the U.S. Geological Survey shows.

The quake's epicenter was 10 miles southwest of Circleville, sending weak tremors up to 2.0 magnitude northward through Beaver and southward through Panguitch and Parowan at 3:14 p.m., the USGS shows. Such tremors are not strong enough to cause damage, the report says.

Since 1962, a total of 47 earthquakes at 3.0 or greater magnitude have occurred within 16 miles of the epicenter of this quake, The University of Utah's Seismograph Station said in a release. The worst of the quakes was a 4.6 magnitude earthquake 4.6 miles northwest of Circleville on Jan. 3, 2011.

The earthquake is located in a "seismically active area of Utah," officials from the University of Utah's Seismograph Station noted. The USGS explains that the quake struck along the intermountain seismic belt, which runs north and south through southern Utah and often experiences clusters of small and moderate quakes.

"It's usually pretty quiet and then you'll see bursts of activity," said Katherine Whidden, a research scientist with the University of Utah. She noted that only one quake was recorded on Tuesday afternoon and there have not been any aftershocks.

"It's a good reminder that we live in earthquake country and the best that you can do is be prepared," Whidden said. To prepare for an earthquake and other natural disasters, visit
