The earthquake yesterday was centred near Arcadia, about 14 miles (23 kilometres) northeast of Oklahoma City, and was about 5 miles deep, the US Geological Survey reported.
Oklahoma Department of Emergency Management spokeswoman Keli Cain said no injuries or damage were reported. A spokesman for the Oklahoma County Sheriff's Office did not immediately return a phone call.
The shaking is increasingly commonplace in the state, so after the initial surprise, customers at a central Oklahoma restaurant returned their attention to an in-state college football rivalry game.
"It shook a bit, that's for sure. Everybody just kind of stopped and looked around," Doepke said. "Everybody almost automatically knew what it was and then went back to watching the Bedlam game" Oklahoma State versus Oklahoma.

Oklahoma is crisscrossed with fault lines that generate frequent small earthquakes, most too weak to be felt. But after decades of limited seismic activity in this region, earthquakes have become more common in the last several years.
Since 2009, more than 200 magnitude-3.0 or greater earthquakes have hit the state's midsection, according to the Geological Survey.
Scientists are not sure why seismic activity has spiked, but one theory is that it could be related to wastewater from oil and gas drilling that is often discarded by injecting it deep into underground wells.
