(AP) -- The U.S. Geological Survey reports several small earthquakes in northern Oklahoma, including three near the town of Renfrow near the Kansas border and about 100 miles north of Oklahoma City.
The strongest temblor was magnitude 3.0 and struck at 9:45 p.m. Wednesday while magnitude 2.6 and 2.3 quakes were also recorded Wednesday night and Thursday morning.
Geologists also report a magnitude 2.8 quake near Minco, about 32 miles southwest of Oklahoma City.No injuries or damage was reported. Geologists say that damage isn't likely in earthquakes below magnitude 4.0.
Many of the thousands of earthquakes in Oklahoma in recent years have been linked to the underground injection of wastewater from oil and natural gas production. Producers have previously been directed to close wells or reduce injection volumes.
