CHICAGO – One of the largest earthquakes in Oklahoma was felt Saturday morning from Nebraska to North Texas.
The 5.6 magnitude earthquake happened at 7:02 a.m. Saturday in north-central Oklahoma, The United States Geological Survey said. That ties for Oklahoma's strongest earthquake on record, the first coming in November 2011.

Oklahoma Gov. Mary Fallin says that crews are checking bridges and structures for damage after the 5.6 magnitude earthquake, which ties a 2011 temblor for the biggest on record in the state.
Fallin tweeted Saturday morning that the Oklahoma Department of Transportation is checking bridges in the Pawnee area for damage. The quake was centered about 9 miles northwest of the town of about 2,200 people.
Fallin also tweeted that state officials want structural engineers to look at building safety in the wake of the quake, which the U.S. Geological Society happened at 7:02 a.m.
People in Kansas City and St. Louis, Missouri; Fayetteville, Arkansas; Des Moines, Iowa; and Norman, Oklahoma, all reported feeling the earthquake. Dallas TV station WFAA tweeted that the quake shook their studios, too.
An increase in magnitude 3.0 or greater earthquakes in Oklahoma has been linked to underground disposal of wastewater from oil and natural gas production. State regulators have asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state. Some parts of Oklahoma now match northern California for the nation's most shake prone, and one Oklahoma region has a 1 in 8 chance of a damaging quake in 2016, with other parts closer to 1 in 20.
Saturday's quake was centered about 9 miles northwest of Pawnee, Oklahoma. Earlier this week, the same spot, which is about 70 miles northeast of Oklahoma City, saw a magnitude 3.2 temblor.
Sean Weide in Omaha, Nebraska, told The Associated Press that he'd never been in an earthquake before and thought he was getting dizzy. Weide said he and one of his daughters "heard the building start creaking" and said it "was surreal."
