Earthquake strikes Salt Lake City


A 5.7 magnitude earthquake shook Utah’s Salt Lake City area Wednesday morning, knocking out power in some areas, officials said.

The 5.7 quake was centered about 10 miles west of Salt Lake City, starting at 7:09 a.m. MT, the U.S. 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 said.

That statement takes into account instrumentation records dating back to 1962 and historical records dating back to the 1850s, the USGS said.

    Lived there, been thru earthquakes there, no biggie. Most of the problem comes to the folks who built in the ‘exclusive’ areas along the bench, much of which is smack on top of the Wasatch fault scarp. My undergrad university built the football stadium on the fault, bleachers on one side are dropping and a swimming club built a pool right over it – they have to patch it every so often as it ‘gets bigger’. Big joke used to be that when The Big One hits those rich folks will be right down in the valley with the blue collar crowd.

      They have some smaller faults in the lake/valley area west of SZLC and the Wasatch Fault that runs from south of Provo north into Idaho is a segmented fault with individual segments having separate quakes. Most segments haven’t had a major quake in the last 1000 years or so and guesstimated quake periods between Big Ones is about 1000 to 2000 years with ones close to 6 about every 350 years so adjust accordingly for your Valley real estate purchases.

      I had to take a few geology classes for my BS (I misunderstood what a ‘BS degree’ was) and spent enough time with the class tromping along the Wasatch and valley faults to get a knowledge both of the area geology and that this was something I did NOT want to do for a living.
