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.

    One more time-keep your eye on Yellowstone-when it pops (and it is overdue), there will be no place to hide.

      I believe these quakes are the result of all the fracking going on in OK. Arkansas had the same thing happen in recent years. There were several quakes and it was determined they were caused from fracking that was going on.

      Becky: Despite the fact that absolutely no fracking operations were being conducted near the earthquake epicenter, and the fact that fracking has never caused an earthquake of magnitude greater than 3.0, if even that. Your belief is irrational and without merit. OK has had quakes this size many times before. Fracking has NOTHING to do with it!

  6. Old Driller w/no TV, long before science learned that the earth wasn't flat, the bible described the earth a "a sphere hanging upon nothing". This was even before ancient Greek universities taught their students that the earth was an hemisphere being supported by four elephants riding on the back of a giant tortois (turtle) They even used to calculate how much weight each elephants leg supported! All the while, bible students knew the earth was a globe. chew on that for a while.

    It's always possible that the 5.6 quake was just a foreshock and the real quake will be a 9.5 killer as soon as you go to bed tonight...

    The earthquake is due to FRACKING. There is a fracking well at the epicenter.

    Oh yeah there is a high chance that we will be hit by another CME from a sunspot that is facing directly at us, it is very large and it appears highly conductive.

    @SailnoailR...and you have spent how many years studying the bible to try and prove it wrong like I did? These 'loopholes' you speak of are just ones you heard mentioned but never bothere finding out for yourself. Any bible student knows it's rediculous to think God causes EQ's or that he made the earth and universe in just six days. Genisis describes God preparing the earth to be inhabited AFTER he had created the universe and the earth. These religions who fleece their flocks lie about God and try to make him appear to be stupid to anyone having a brain...even saying that he is an exprtionist who would have his children burned forever if the disobey too much! Even a child molester knows better than to light a puppy on fire for pooping on the rug one too many times! The leaders spewing these lies are not representing the God of the bible as they claim.

    More people were killed, and probably more damage was done, by deer strikes last week in Oklahoma than this quake.

    No, you heard on the news that it's "fracking". In reality, you haven't a clue. gb
