A magnitude 4.9 earthquake rattled parts of Utah, Wyoming and Idaho on Thursday evening. There were no immediate reports of significant damage or injuries.
University of Utah officials say the quake hit just before 6 p.m. MDT. The epicenter was about five miles east-northeast of Randolph, a tiny town about 73 miles northeast of Salt Lake City.
The quake was the largest in Utah since a magnitude 5.9 temblor hit near St. George in 1992, according to Relu Burlacu of the University of Utah seismograph stations.
The U.S. Geological Survey Web site logged more than 1,400 responses from people who said they felt Thursday's quake less than an hour after it struck. Responses ranged from Provo, Salt Lake City and Ogden to Jackson, Wyo., and Pocatello, Idaho.
Four earthquakes with a magnitude 3.0 or greater have struck within 16 miles of the epicenter since 1962, according to officials at the University of Utah seismograph stations. The largest was a magnitude 3.8 in 1979.
A 4.6 quake struck in 1966 within 32 miles of Thursday's epicenter.
