A 4.7 magnitude earthquake occurred in Oklahoma (video) and was felt in Kansas 33 km (20 miles) NE of Shawnee, Oklahoma, 67 km (41 miles) W of Okmulgee, Oklahoma, 68 km (42 miles) SSE of Stillwater, Oklahoma, 75 km (46 miles) E of OKLAHOMA CITY, Oklahoma.
It is the 3rd largest earthquake in Oklahoma history, and some mistook the shakes as a plane crash. The LA Times adds:
The quake was followed by nine aftershocks in the same area, Caruso said.
He said it was difficult to say what caused the quake, but that it originated from rocks moving sideways on a "strike slip" fault similar to the San Andreas Fault. The Oklahoma fault is known as the Wilzetta Fault, also the Seminole uplift, according to the Oklahoma Geological Survey, which reported more than 30 aftershocks associated with Saturday's quake.
No injuries have been reported, but there have been reports of minor damage from items falling off walls, according to staff of the Lincoln County sheriff's office who spoke with The Times.
Oklahoma City police told The Times they have received several 911 calls but no reports of injuries or damage.
