Magnitude 5.6 Oklahoma quake
11/6/2011 10:53 p.m.
The WFAA newsroom was inundated with calls and messages from viewers who said they felt an earthquake around 11 p.m. Saturday.
The U.S. Geological Survey reported a 5.6 earthquake centered 45 miles east of Oklahoma City at 10:53 p.m. and felt in seven states. That would be Oklahoma's most powerful quake on record, and one capable of causing minor damage to buildings and other structures.
Michelann Ooten, a spokeswoman for the Oklahoma Department of Emergency Management, said no injuries were reported and she had no reports of major damage.
Within the next two hours, WFAA received more than 1,500 Facebook comments from viewers — most of whom reported having felt a jolt shortly before 11 p.m.
"Felt it in Bryan Place just east of downtown Dallas," said John MacGregor. "My wife said, 'What is that? Look at your drink, it's moving!' It was!"
"I felt it here in Flower Mound around 10:55," said David Murray.
"We felt it in north Parker County about 11 p.m.," said R. Terry Lee. "Lasted about 30 seconds."
"I felt it in Keller/Fort Worth," Lindsey Cattoor reported. "My entire second story started shaking, parents didn't feel anything downstairs."
Amanda Nelson said: "We felt it here between Azle and Springtown. Family in Harrison, Arkansas and Joplin, Missouri felt it at the exact same time! Weird!"
"Our furniture rocked back and forth for about 15-20 seconds here in Rockwall," Stacy South reported via Facebook.
"I felt it in Little Elm close to 11 p.m.," Joe Deaver said. "Didn't even realize that's what it was, as it was my first. :-)"
There have been no reports of any seismic activity centered in North Texas, but as of late Saturday night, the USGS Web site said it had received more than 4,500 responses from 901 zip codes in the wake of the Saturday night earthquake in Oklahoma. The reports came from Oklahoma, Texas, Illinois, Missouri, Kansas, Arkansas and Arkansas.
The reports Saturday night follow a swarm of earthquakes in Central Oklahoma early Saturday morning.
