See the Moment the Oklahoma Earthquake Hit -- Including ESPN Reporter's Wide-Eyed Reaction On Air

Oklahoma is rattled after the state's strongest earthquake shook the ground for nearly a minute Saturday night.

The magnitude 5.6 quake was centered near Sparks, about 44 miles northeast of Oklahoma City. It was followed by a series of aftershocks Sunday morning, including two with 4.0 magnitudes.

No major injuries have been reported, but homeowners and businesses noted cracked walls, fallen items and other minor damage. The Shawnee Fire Department told KWTV in Oklahoma City one spire on the administration building at St. Gregory University had been damaged and another one was leaning.

At least three sections of U.S. Route 62 reportedly buckled as a result of the quake, which was felt as far away as Wisconsin and Tennessee.

At least eight earthquakes were felt during a 24-hour period that kicked off early Saturday with a magnitude 4.7.

Residents quickly uploaded their own videos capturing the moment the temblor hit.

Content warning -- strong language

And finally, ESPN's Kirk Herbstreit was on the air reporting on the Oklahoma State-Kansas State football game at the time of the quake. Watch his eyes as he realizes what's happening, then is unable to answer a question about his report.
