Authorities say three earthquakes that have shaken much of central Oklahoma could be felt as far away as Kansas, Missouri and Arkansas.
The U.S. Geological Survey says on its website early Saturday morning that a 4.7 magnitude earthquake struck at 2:12 a.m., with an epicenter about six miles north of Prague in southern Lincoln County. That's about 50 miles east of Oklahoma City.
A 3.4 magnitude aftershock was reported at 2:27 a.m. from the same location.
The survey says a 2.7 magnitude quake also was recorded at 2:44 a.m.
Lincoln County sheriff officials say there have been no reports of injuries but several people have reported items falling off walls.
Oklahoma City police officials say they have received several 911 calls, but have no reports of injuries or damage.
