Two small earthquakes have been detected in central Oklahoma.

The U.S. Geological Survey says a magnitude 2.9 quake rumbled just before 2 a.m. Friday near Dibble, about 25 miles south of Oklahoma City. A magnitude 2.7 quake gave Lincoln County a mild shake at about 10:30 p.m. Thursday.

The Lincoln County quake was near Sparks, where a magnitude 3.9 quake shook the largely rural area about 50 miles east of Oklahoma City at about 4:15 p.m. Thursday.

No damage has been reported from the earthquakes.
