FAIRVIEW, Oklahoma — A 4.2 magnitude earthquake is among six that have rattled Oklahoma.
The U.S. Geological Survey reports that the 4.2 magnitude quake happened Tuesday northwest of Fairview at 2:45 p.m. A 3.0 magnitude quake struck about three hours later near Medford.
Two more of the quakes also happened near Fairview on Tuesday — a 2.9 quake and a 2.6 quake.
Tuesday morning, a 2.8 quake struck near Prague at 6:41 a.m. and another hit near Mooreland, registering a 2.6 magnitude at 8:09 a.m.
No injuries or damage were immediately reported.
Oklahoma's earthquakes have been linked to the injection of wastewater underground from oil and gas production.
State regulators have recommended reducing the volume or shutting down some of the disposal wells.
