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.

      I don't see why she wouldn't be happy? Oklahoma City is a great city. We had aftershocks all day yesterday and nobody felt a thing. Besides, the damage from these quakes isn't in the city, it's in the small towns miles away.

    Earthquakes happen all the time. No reason to panic. It's only that the news report on such events more than before. There are thousands of earthquakes every day. Nothing abnormal is going on. There's nothing to see here. Go home. Keep shopping.

      Sure it is. Someone who has never experienced one, or it's aftershock, might be a wee bit afraid though, no?

    • Okie83

      Yes earthquakes happen all the time but when a 5.6 hits an area where there are no structures built to withstand major earthquakes it is kind of a big deal. There are hundreds each year in OK and normally around 500 per year. Last year there were 1,000 in OK though and this is the largest the state has ever witnessed. So, big changes are ongoing on the faults throughout the plains and this can cause short and long-term issues here. We're sorry we aren't accustomed to this, would you like an F4 or F5 tornado to rip through your state and not be covered by the media??

      sorry buddy but you are sadly mistaken, no well in the US is 15840 feet deep better do some research 1st most directional wells only go down 4000-5000 feet and "kick off" horizontaly

      The Oklahoma Geological Survey posted a report conducted in August 2011, notating wells at 10,000'

      yeah, well I worked a well in south east Oklahoma that was 26,300 ft. in the"potato Hills" it is in the south east corner of Oklahoma, it was called the Mary 2-34 it was about 5 years ago. I think you need to do the research.

We've always had EQ's...not near as many, but still they are natural. Since EQ's came out of the closet, many ignorant people have looked down on them...many even saying that God made them this way. Please join with me getting the word out that EQ's are ok even in OKlahoma. Ththank you tho much for for reading my pothst.

    Biggest quake since 52? I disagree! The ones generated between the Cornhuskers and the Sooners in Switzer's tenure were much bigger. They sure don't make smash nose college football like they used to.

    Oil and gas exploitation has made the subsurface a bit fragile. Not to worry in 10,000 years no one will remember any of this.

    The quake was unlikely to be caused by Fracking given the depth. However I'm wondering if the fracked region could act as an amplifier for the quake? Like tapping an open paper bag is noisier than tapping a flat one. Any thoughts on that?

      More likely, it would absorb the vibrations without transmitting it further. Compare: a knock to the end of a solid rod and a knock to the end of a broken rod. Which one reaches the other end of the rod intact?

    Anyone who says OKC is a nice place to live does not know better. I lived there for a year and became deeply depressed. It's SO boring and filled with right-wing nut Christians who preach what they themselves don't follow. The weather there is ridiculous and it is so flat and barren. All there is to do there is GET PREGNANT. It's pathetic. Now that I'm in Houston I can finally be around cultured people once again and I couldn't be happier.

      There are many educated people from around the globe here in Houston and I appreciate that. It's only the murder capital if you are uneducated and live in the ghetto. I saw none of that in Oklahoma City. And to respond to Britt, no I choose to have children when I am well established in my career and I could care less about football, it is silly and boorish. You sound like white trailer trash, maybe an OU graduate?
