3.7 magnitude earthquake recorded
RIPLEY The U.S. Geological Survey has recorded a magnitude 3.7 earthquake in northern Oklahoma.
The USGS reports the quake struck at 9:33 a.m. Thursday near Ripley, about 50 miles northeast of Oklahoma City. No injuries or damage are reported and geologists say damage is not likely in earthquakes below magnitude 4.0.
The earthquake came following a 2.5 magnitude temblor at 2:08 a.m. near Waynoka, about 95 miles northwest of Oklahoma City.
Thousands of earthquakes have been recorded across Oklahoma in recent years, and many have been linked to the underground disposal of wastewater from oil and natural gas operations.
Regulators have asked oil and natural gas producers to close injection wells in certain areas or reduce the volume of fluids they inject.
