Neither injury nor damage was reported Wednesday morning when a minor earthquake, measuring 3.5 on the Richter scale, shook the Park City vicinity.
People as far away as Sandy felt the temblor, which struck at 9:27 a.m. The epicenter was about four miles west of Park City, said Julie Bernier of the University of Utah Seismograph Stations."It was kind of like a boom -- you could hear it. Then it rumbled for three or four seconds and the house shook," said Sue Harman of the nearby Pinebrook subdivision. "The house kind of moved."
Susannah Moran, 21, a college student from the University of Kansas, who is working in Park City for the summer, said: "I thought that was a mighty big truck that went by."
"Shook the lamps on the night stands, woke me up," reported Rick Walton, who lives at 8000 South and 3300 East. He was in bed because he works nights. "I thought an accident was happening, so I ran outside to see if something had hit the house. A neighbor came running out from across the street and said, 'Did you feel something?' " Then they realized it was an earthquake.
A spokeswoman for Sandy police said the department received a few telephone calls about the rattling, people "just asking what the explosion was." Some of the callers thought the concussion was from the Utah National Guard setting off detonations at Camp Williams.
Rob McQuay, an architect at Kimball Junction, Summit County, said a lot of blasting has been going on in his vicinity, but he could tell this was definitely an earthquake because of the duration. "It shook laterally for about five seconds," he said.
The Park City Police Department had no reports of serious damage, said Debbie Long of the department. "The most is a cup tipped over. . . . Mostly, people felt the shake."
Margie Maruki of the Marriott Summit Watch condominiums in Park City said she and an associate took 10 to 15 calls from guests within a quarter-hour.
"We had people calling from the third and fourth floors of the lodge, wondering if there had been an earthquake . . . wondering if a car had hit the side of the building," she said.
One woman bet her children that it wasn't actually an earthquake because she had slept thorough it, Maruki said.
