PAWNEE, Okla. (AP) -- The U.S. Geological Survey has recorded five small earthquakes in northern Oklahoma, including a magnitude 3.9 temblor near Pawnee where the state's largest earthquake was recorded in September.
A 3.6 magnitude quake also struck overnight near Cushing, one of the world's major oil hubs. Five quakes have been recorded in the state since Sunday night.
No injuries or damage have been reported.
The USGS says one quake hit at 9:22 p.m. Sunday, about 9 miles east of Pawnee. That was followed by the temblor about 3 miles north of Cushing at 2:58 a.m. Monday.
A 3.2 magnitude quake was recorded at 11:39 a.m. Monday, nine miles west of Perry, while magnitude 2.7 and 2.8 quakes were recorded Sunday night and early Monday near Pawnee.
Oklahoma's earthquakes have been linked to oil and gas production.
