USGS: 5.6 magnitude quake rattles Oklahoma; temblor may be record for state

November 5, 2011, 11:31 p.m. Updated November 6, 2011, 1:05 a.m.


— One of the strongest earthquakes in state history rocked central Oklahoma late Saturday after a day of smaller quakes, a 5.6 magnitude temblor that rattled a college football stadium 50 miles away, shook buildings, caused cracks and was felt as far away as Tennessee, authorities said.

Emergency authorities had no immediate reports of injuries or major damages. But one county’s sheriff’s office in the region said it was responding to calls and damages. The reports in the late-night hours were sketchy and the extent of damages remained uncertain early Sunday. The quake was one of several to rattle the state Saturday, including a magnitude 4.7 earthquake that shook the same area early Saturday.

The quake could prove the most powerful on state record if the 5.6 reading reported by the U.S. Geological Survey stands. The seismic monitoring agency said the quake struck at 10:53 p.m. local time Saturday (0353 GMT) and was centered about 44 mile east-northeast of Oklahoma City. It had initially reported the temblor as a 5.2 magnitude quake.

It said the quake struck near the community of Sparks — in eastern Oklahoma between Oklahoma City and Tulsa. The temblor shook the stadium at Oklahoma State University in Stillwater just at the end of the school’s football game with Kansas State. No. 3 Oklahoma State’s players were gathered in the locker room under the Boone Pickens Stadium stands just after a 52-45 win against No. 17 Kansas State when the ground began to shake.

“Coach (Mike) Gundy was talking to me, everybody was looking around and no one had any idea,” quarterback Brandon Weeden said. “We thought the people above us were doing something. I’ve never felt one, so that was a first.”

The shaking could be felt in the stadium’s press box for the better part of a minute before it subsided. The stands were already clearing out when the quake happened, just a few minutes after the down-to-the-wire game had ended.

“That shook up the place, had a lot of people nervous,” OSU wide receiver Justin Blackmon said. “Yeah, it was pretty strong.”

Michelann Ooten, a spokeswoman for the Oklahoma Department of Emergency Management, said no injuries were reported to emergency management officials and that there had been no reports of injuries. She also said the authorities had no immediate reports of major damages.

The U.S. Geological Survey reported from Golden, Colo., on its website that it monitored a 5.6 magnitude quake at 10:53 p.m. local time Saturday and said it was centered about 44 miles east-northeast of Oklahoma City. It had initially reported the temblor as a 5.2 magnitude quake.

If the intensity of the Saturday night quake is confirmed, it would be the state’s strongest on record. USGS records show that a 5.5 magnitude earthquake struck El Reno, just west of Oklahoma City, in 1952 and, before Oklahoma became a state in 1907, a quake of similar magnitude 5.5 struck in northeastern Indian Territory in 1882.

The Saturday night quake was felt as far away as Tennessee and Wisconsin, according to reports received by the USGS.

Some in Oklahoma reported cracks appeared after the latest quake.

“There’s a crack going from the closet to the ceiling. I’ve never seen that before. I was in my bedroom grabbing my phone and I happened to notice it,” said Todd McKinsey, in the community of Moore, speaking with The Oklahoman.

Saturday’s earlier temblor, which hit at 2:12 a.m., woke people and pets as it shook an area that stretched from Texas to Missouri. Its epicenter was 6 miles north of Prague in Lincoln County, in the rolling hills about 50 miles east of Oklahoma City.

A 3.4 magnitude aftershock was reported at 2:27 a.m. from the same location, as well as a 2.7 magnitude aftershock at 2:44 a.m.

“Oh, man. I’ve never felt anything like that in my life,” Prague City Police Department dispatcher Claudie Morton told the Tulsa World. “It was the scariest thing. I had a police officer just come in and sit down and all the sudden the walls started shaking and the windows were rattling. It felt like the roof was going to come off the police department.”

Morton said the office was flooded with calls, but no one reported injuries or major damage. She said residents told her that picture frames and mirrors fell from walls and broke, drawers worked loose from dressers and objects tumbled out of cabinets.

“We do have several damaged buildings downtown, but it’s just cracks and things like that,” Morton said. “Nothing is destroyed or anything like that.”

Oklahoma Geological Survey researcher Austin Holland told Oklahoma City television station KOTV that the earthquake and aftershocks occurred on a known fault line.

Residents in Prague and Sparks felt an intense shaking, while farther away, the quake was more of a dull rumble, he said.

“It shakes much more rapidly when you’re closer to it,” he said. “Because it’s a large earthquake, it’s going to rumble for a while.”

Holland said his office received hundreds of emails from people who felt the quake. The messages came from as far as Texas, Missouri and Arkansas, he said.

Tom Foster of Oklahoma City told The Oklahoman that he slept through the earthquake but was awakened by an aftershock.

“I know we’ve already had several phone calls from out of state relatives wondering what happened,” Foster said. “I guess it’s more interesting than anything that was dangerous.”

Heather Spicer of Sapulpa said the shaking woke her son and their dog.

“At first I thought an airplane had crashed nearby,” she told The Oklahoman. “But now I believe it was an earthquake because the whole house just kept vibrating with what sounded like distant thunder outside.”

In Muskogee, retired advertising and public relations executive Robert Rhea said he felt his home rocking for about 15 to 20 seconds with the last quake Saturday night..

“Oh man, it just about shook this old man out of his TV chair,” said Rhea, 70, speaking with The Associated Press by telephone. He said nothing broke in his homes but he was rattled by all the shaking during the day.

Felt it out here by Clinton Lake while sitting in a chair. Got a call from daughter on 9th floor of dorm sort of freaked out about the shake.

Felt it out by Hallmark sitting in my chair. I was thinking my dog was by the chair scratching, but no dog was around.

Joe Hyde 6 years, 7 months ago

That's the same thing I thought -- dog lying behind the sofa with its back against the sofa, scratching itself. The sofa's vibration had that same sort of rhythm.

At 14th and Mass. I could feel my chair shaking slightly as I had before some years ago when a minor quake hit. I thought it was the blood in my body moving my body in the chair, the same as I thought the other time, before I knew that a quake had hit.

First earthquake since my S.F. days. Hope everyone in Oklahoma is O.K.

Four of us watching in basement watching SNL, dog on floor and cat on back of chair--none of us noticed it. How disappointing! Maybe it is amplified on upper floors of a building??

Wife felt it downstairs in our bilevel - said her desk and ground rumbled/vibrated for about 30 seconds. I was upstairs and didn't feel/hear a thing.

My labrador retriever growled at it but I just thought it was distant thunder. She knew it wasn't that. Damn.

Steve Dittmann 6 years, 7 months ago

We were at the movie theater. Both my wife and I felt the seats shake but the picture didn't. Nobody else seemed to notice it. Lasted about 10 seconds I think.

12th and Oread, thought the people downstairs were going at it.

Woo...that was freaky! I was sitting on the couch and felt it.

waitjustaminute 6 years, 7 months ago

Here in SW Lawrence, thought it was a high wind blowing. Pocket doors rattled, cat and I took notice. Jumped on computer later, confirmed on Drudge is was an earfquake way down in Okieville. Damn cable went out briefly too.
