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.

    @ DAD.. $ 25.00 for EQ Insurance a year... sounds to good to be true in any state, you forgot to mention the 10-15 %
    Deductible... on.. let's say a home insured for $ 200,000.00 so you have to Cough Up the 1st $20,000 or $ 30,000.00 Grand, so that $ 25.00 doesn't look so good now.. and those cheap premiums will be going up in good ol Okie.

    Interesting it says 300 million years, since the Earth has only existed for about 5000 years. But that goes to show how lacking scientists are in knowing how to accurately date things.

      Stop using your bronze age Bible as a science book Moron. Science has only been in existence for a few hundred years. It is separated from the Old Testament by thousands of years and the people who wrote it had limited knowledge of their world and anything remotely scientific. The evidence for and ancient earth are so overwhelming that your pseudo scientific nonsense is laughable and ridiculous.

    haha, show how much you know about the Earth, troll. Anyways. Does anyone else notice all these freak Earthquakes going on since Fracking has begun? Just because gas companies are making money... we're all going to suffer destruction which will cost a lot more than the profits they will make. Here we have the few making money off the many. Europe has already banned this destructive practice. When will the US wake up?

      just reading the comments , yes the Earth and her sister planets plus Sun are billions of years old A67 seems to want to put Religion in the mix , ia m not against that , but lets get out of the middle ages , as far as WhackyWaco comment dude, get a life, and on fracking people get real u want power to get on the net an make comments , guess what u need power to do that , and btw , all the easy stuff is just about gone, now we have to drill deeper come up with new ways of getting the fossil fuel u so need , , since no one wants to use the nukes to make power , an on fracking no it dont make the Earth shake any more than pumping out the oil we already have pumped , so make up ur mind , either use the nukes or use what we have , but make more intelligent comments in the future btw electric cars only will make more demand on the power grid think on that .

      Yes. Hydrofracturying, aka "fracking", appears to be the cause. Earthquakes caused by human activity "induced earthquakes" are shallow depth, according to MIT and Stanford. The US Department of Energy: "Another type of induced seismicity is that which is associated with “hydrofracturing”. Hydrofracturing is done by injecting fluid into the subsurface to create distinct fractures in order to link existing fractures together in order to create permeability in the subsurface." Don't listen to deniers. Induced earthquakes are also proven to be caused by Enhanced Geothermal Systems, Nuclear Fuel Re-processing (MOX) and Carbon Sequestration ("clean coal"). All of these receive federal tax payer grants esp. through the 2009 ARRA: American Recovery & Re-investment Act. These are Obama's "hi-tech, green jobs of the future"...AND this is what he wants more money for in his new "jobs" bill.

      Totally agree. California's central valley now gets earthquakes thanks to fracking. That area never had quakes before.

      Southern Colorado had the same problem with frequent low-level quakes – until the fracking stopped! Go figure. Hey, CNN – perhaps you should do a little more in-depth reporting. Oh, wait, that's not the MO.

  5. Really

    I love how people try to come up with theories and reason and excuses as to why we shouldn't be concerned about the recent earthquake activity. Yes, earthquakes have been happening for years, so have food shortages and pestilences, so have wars. BUT when have all of these things ever in the history of mankind happened at the same time in one generation, in such a short period of time? THAT is what makes these issues we are having very different and THAT is why we are living in the last days, so says the bible.

      This does not necessarily mean the apocolypse is coming, but the events are increasing. Think of all the crazy things that have happened in this year alone. The media didn't just all of a sudden decide to cover more stories. If you cannot notice what is going on, that the events are increasing, you are most certainly blind.

    I knew it wouldn't take long before someone brought up the Bible reference. Here in Missouri the New Madrid fault zone shook the region for 8 months. I can understand why folks in 1803/04 thought it was the wrath of God, they didn't know any better. Today we know God as a creation of Man, just as Oklahoma earthquakes are caused by man in his search for fuel. Too bad man just doesn't look to the sky and see the sun, not the imaginary heaven, all his energy problems would be solved.

  11. Old Driller w/no TV

    Fraccing (not 'fracking') was invented by Halliburton back in the 1950s and has been used worldwide since to bring old oil and Ng wells back on line. The real cause of increased EQ activity is this: since the industrial revolution water has been taking longer and longer to evaporate because of the shade of pollution. This has led to global temperatures rising, which causes the moleculuar volume of air do decrease. This, coupled with less evaporated water in the air, has reduced the amount of pressure that naturally weighs upon the earths surface. The atmosheric pressure at sea level is still 14.696 psi...but this measurement doesn't take into account the reduced psia (pounds per square inch actual) The actual pressure upon the earths surface that keeps the earth from quaking too much is less now than ever before...hence, more EQ's. (God does not cause EQ's...both he and his son knew they would increase, and so warned us well in advance)

      Atmosperic pressure is 14.696 psi absolute with 0 psi absolute being a complete vacuum. If you are saying that the weight of the atmosphere above the earth has been reduced, then in fact you are arguing that atmospheric pressure is no longer 14.696 psia. A simple check of barametric pressure records should help prove/disprove this trend you speak of.

    Solar cycle is getting warmed up and since the peak is 2013 I think we can expect more quakes and Canos to come to earth as a result of all the electo-magnetics and intense solar radiation! Sunspot 1339 is 39 times the size of earth and is facing us right now and has been rather active w x and m class flares.
