Earthquakes Utah

A moderate earthquake shook southwestern Utah early Wednesday, triggering a rockslide that closed Zion National Park and sent three houses slowly sliding down a hillside. Minor damage was reported elsewhere. No injuries were reported. Dozens of people called radio stations with reports of cracks in windows, foundations and ceilings in older homes, as well as buckled sidewalks and asphalt. Walter Arabasz, director of the University of Utah Seismograph Stations, said the earthquake measured 5.

A magnitude 5.5 earthquake shook a large area of northern Arizona and southern Utah early Thursday, causing a brief power outage at Grand Canyon Village, Ariz., and waking residents of Flagstaff, Ariz. Douglas Bausch, interim director of the Arizona Earthquake Information Center, said the quake occurred at 1:21 a.m., seven miles beneath the Earth's surface on the occasionally active Cataract Creek fault system, with the epicenter 25 miles south of the Grand Canyon.

A moderate earthquake centered in eastern Utah shook an area 200 miles wide, triggering rockslides that closed at least one road but causing no major damage or serious injuries. The quake, measuring 5.6 on the Richter scale, was centered near Ferron, about 135 miles east of Salt Lake City. Several rockslides occurred in eastern Utah canyons, and the Huntington Canyon Road in Emery County was closed because of a slide, according to the Utah Highway Patrol.

An earthquake measuring 3.4 on the Richter scale shook parts of northern Utah on Wednesday, but there were no reports of damage or injury, officials said.

An earthquake measured at 2.1 on the Richter scale rattled northeastern Salt Lake City but was unrelated to a series of tremors that shook central Utah earlier this month, seismologists said. No damage or injuries were reported.

A small earthquake of magnitude 3.2 shook central Utah on Monday, but no damage was reported.

An earthquake measuring 3.5 on the Richter scale shook an unpopulated cattle-grazing valley in northern Utah Wednesday, officials said. No damage or injuries were reported.

An earthquake shook most of Utah and parts of western Colorado and Wyoming, rattling homes and knocking objects off walls, but no major damage or injuries were reported, authorities said. The quake was centered about 140 miles south of Salt Lake City, near the central Utah community of Salina, and had a magnitude of 5.4, said Russ Needham, a geophysicist with the U.S. Geological Survey's National Earthquake Information Service in Golden, Colo. "It was pretty strong.
