Oklahoma can expect more quake aftershocks, USGS says

Aftershocks from Saturday's 5.6-magnitude earthquake in Oklahoma are likely to continue for weeks or even months, the U.S. Geological Survey says, but rattled residents can expect them to decrease in intensity.

The USGS says dozens of aftershocks from the temblor, and a 4.7-magnitude foreshock, have been recorded since the 5.6 quake hit at 10:53 CT Saturday night.

The Oklahoma Geological Survey says the quake was the largest ever to strike in the state, topping a 5.5-magnitude temblor that struck on April 9, 1952.

Saturday's quake was centered about four miles east of Sparks, in Lincoln County, Oklahoma. The USGS says on its website that it has not been able to determine what fault line the quake occurred on, but scientists are focusing on the Wilzetta fault, which they describe as one of a series of small faults that formed in the area about 300 million years ago. If the Wilzetta fault did rupture Saturday, it would be the first time a surface-rupturing quake has been recorded on it.

All previous surface-rupturing quakes in Oklahoma have occurred on the Meers fault, in the south-central portion of the state, the USGS says.

Damage from Saturday's quake was slight, with The Oklahoman newspaper reporting minor damage to 12 homes and a buckling of U.S. Highway 62 near the epicenter in Lincoln County.

But the quake was anything but minor to one couple whose home sits near the epicenter. The chimney of Joe and Mary Reneau's home came crashing through their roof in Prague, Oklahoma, CNN affiliate KJRH-TV reported.

"Wham! It wasn't just a sudden bang,” Joe Reneau told KJRH. “This house was rocking and rolling."

But it wasn't just people that the quake stirred up. Birds and bugs were so rattled that they took to flight in massive numbers, enough to show up the National Oceanic and Atmospheric Administration's weather radar, CNN affiliate KTUL-TV reported. Check out the radar images here.

    Aftershocks? Mineral VA has had 45 since the 8/23 quake that measure 2.0 and above and they still keep coming. Many more are being continuously felt in the immediate area by residents. The damage to personal property has surpassed $19million and at last count only 26 people had earthquake insurance. 2 schools were lost. Thankfully none of our children were hurt. Fema just ok'd help and insurance companies have been reluctant to pay for damages as winter approaches. Could be a mild winter as we continue to 'heat the outside' due to open gaps in our walls and chimneys. good luck to Oklahoma! Our thoughts and prayers are with those who suffered losses.

      @Jeff I AM SO SICK OF HEARING CALIFORNIANS pooh pooh anyone outside of CA expressing their reactions to the EXTRAORDINARYILY unusual earthquakes happening in other states. In '08 and '10 we felt earthquakes near Chicago. One was centered in my town. Siesmologists reported there are no known faults here. It was scary as hell BECAUSE WE DON'T GET EARTHQUAKES NEAR CHICAGO. OR VIRGINIA OR OK OR ARKANSAS. Yet they are happening with great frequency. Yes, GREAT frequency in comparison to past history. So Californians, keep your snide comments to yourselves.

      And no, the Chicago area quakes were not related to the New Madrid fault. No where near.

      Fracing does not cause earthquakes. There's so much ignorance about what fracturing does and how we perform it, that everytime I hear someone make a comment like this, I laugh. I can understand that not everyone knows what we do, and we'd be more than happy to show you how we frac, but people would rather condemn before learning the real truth. Also, all you anti-fracing, anti oil people out there better listen up....without it, you'll be paying $40-$50 per gallon for gas, higher prices for food, clothes, and anything that has plastic in it or is a by-product from oil. Getting rid of oil & gas is not going to happen.

      @Lou, without people like you we would have developed cleaner methods of power out of necessity and not be in wars over oil, polluting the air so much, and be bringing jobs home. But we are where we are and we still need to move on and get away from stupid methods of power.

    Members of the Oklahoma Legislature, please give your fellow Representative Sally Kern a bottle of Bean-O. Prevent a calamity to your great state!

      Your comment was in very poor taste.She has more insight than anyone gives her credit for. It was her who put the no shariia law on the ballot which was voted for by a wide number and was approved. Now some judge has taken it on herself to keep that law from coming to reality. Now in several other states judges have used Sharia law. It has NO PLACE in America. Before long it will be forced on every American, the antichrist will rule and you will not be able to buy or sell unless you allow a microchp to be be implanted in on your forehead or palm.All these things willl no coming to pass soon. Read your Bible see all the prophecies coming true. There will be earthquakes in many places, LOOK at the last 2 years. Rep KERN has the insight many other politcians....all the liberals

    • Huh?

      bjlucky:
      Are you saying because a loving mother defends her kids, she's automatically a single welfare mother from a blue state? What"s the matter, did your mommy never show you any affection? What a wibble you are.

    Congratulations! This is the second interesting thing that's happened in Oklahoma in my lifetime – the only other I can remember was the bombing of the Federal Building. Keep up the good work!

    "The Oklahoma Geological Survey says the quake was the largest ever to strike in the state, topping a 5.5-magnitude temblor that struck on April 9, 1952." OMITTED: the statement "since records have been kept."

    These earthquakes are taking place in OK because of the fracking. Look it up...it's all in the region of the major fracking. It's happening in the exact same way in Arkansas.
    Lets see if we can just totally destroy the earth that we're living on.
