5.7 Magnitude earthquake shakes Salt Lake City

The US Geological Survey reported a Magnitude 5.7 earthquake that shook residents in Salt Lake City, Utah early Wednesday morning.

The quake was felt up and down the Wasatch front at 7:09 a.m. MDT., 6:09 a.m. Pacific Daylight Time and shook Utah's Salt Lake City area knocking out power in some areas, officials said.

The 5.7 quake was centered about 10 miles west of Salt Lake City, the US Geological Survey said.

"From what we have been able to determine, it doesn't appear this was major shaking," Utah's Division of Emergency Management posted on Twitter shortly after the earthquake.

Still, power has been knocked out in some areas, and aftershocks are likely, the division said. Details about the extent of the outages weren't immediately available.

At least six aftershocks had been recorded within 20 minutes of the main quake, according to the USGS.

This is the state's most powerful quake since 1992 when a magnitude 5.9 temblor struck the St. George area, the division said.

Generally in Utah, earthquakes greater than magnitude 5 happen once every 10 years, and quakes greater than magnitude 6 happen once every 50 years, the USGS says.

That statement takes into account instrumentation records dating back to 1962, and historical records dating back to the1850s, the USGS says.

There were no immediate reports of major damage or injuries.
