WELLS, Nev., (AP) - A strong earthquake shook rural northeastern Nevada Thursday, causing at least one building to collapse, authorities said.

The magnitude of the quake, initially estimated at 6.3, was later revised to 6.0 by the U.S. Geological Survey's National Earthquake Information Center in Golden, Colo.

The quake, which struck at 6:16 a.m., was centered in a sparsely populated area 11 miles southeast of Wells near the Nevada-Utah line.

''It was pretty bad,'' said Jane Kelso, who answered the phone at the Motel 6. ''Everything in our whole building shook. ''We have cracks in our walls.''

Three people have been injured as a result, local officials say.

The temblor was felt across eastern Nevada, Utah and as far away as Southern California. In Twin Falls, Idaho, residents reported severe shaking and items falling off shelves.

''Definitely a lot of people felt this, and if they were sleeping, they were awoken,'' said USGS geophysicist Carrieann Bedwell.

Elko County Undersheriff Rocky Gonzalez said there were reports of some damage to buildings. At least one building collapsed, he said, and a Flying J truck stop was evacuated because of a propane leak, he said.

There were no immediate reports of serious injuries, but a manager at the truck stop said the store was a wreck, with groceries and goods scattered. One woman was reportedly injured when cigarette rack fell on her.

Charlie Meyers, Elko County commissioner, said the county commission is issuing a state of emergency for Wells, which should open the door to state and federal assistance. No one is being allowed into Wells, Meyers said, because of the fear of aftershocks.

Nevada's Department of Transportation is checking bridges, overpasses and roads in the town to make sure they're safe.

In Wendover, Utah, on the Nevada-Utah line, Tammy Wadsworth was ironing clothes when the quake hit.

''I kept thinking, 'When is it going to quit?' A couple pictures fell off the walls,'' she said. ''One of my grandkids ran outside. They didn't know what else to do. It scared them.''

Ada County officials in Boise say they received about five calls Thursday morning asking if there was an earthquake.

Officials say temblors were felt across the region, with reports of minor damage, falling dishes and cracked house foundations from Boise to Twin Falls.

Twin Falls Sheriff Department official Susan Donat says there are no injuries or reports of major damage in the county. She says
the department received a flood of calls moments after the initial temblors were felt, but reports have tapered off.

KIDK in Twin Falls is reporting that Highway 93 south of Jackpot, Nev., is closed.
