A small earthquake "definitely rattled things" in southwestern Utah Tuesday, a seismologist said. There were no reports of injuries or damage.
Linda Hall, research seismic analyst at the University of Utah Seismograph Stations, said the quake occurred at 11:42 a.m. MST and registered 3.7 on the Richter scale.Its epicenter was eight miles north-northwest of Zion Park Headquarters in the vicinity of North Gates Peaks and was felt in Hurricane, Hildale and St. George, she said.
A temblor of magnitude 3.4 was recorded March 22 10 miles northeast of Cedar City at the southwest end of the Parowan Valley. Hall said while the quakes were both located in southern Utah, they likely were not related.
The Richter scale is a gauge of energy released as measured by the ground motion recorded on a seismograph. A magnitude 3.5 quake can cause slight damage.
