MEDFORD, Okla. (AP) – A series of moderate earthquakes continues to shake northern Oklahoma, near the Kansas border.
The U.S. Geological Survey recorded a 3.7 magnitude quake two miles west of Cushing at 1:59 p.m. Sunday, following 3.5 and 3.4 magnitude quakes nine miles northwest of Medford at 10:04 p.m. Saturday and 2:29 a.m. Sunday. Magnitude 2.9 and 2.5 temblors were also recorded Sunday near Medford.
No injuries or damage are reported.
The quakes come after 17 earthquakes were recorded in the area from Friday night through Saturday afternoon – including magnitude 4.2 and 4.1 temblors near Medford that were reported felt in Oberlin, Kansas, some 400 miles away.
The Oklahoma Geological Survey has said many recent earthquakes in the state likely were triggered by the injection of wastewater from oil and natural gas drilling operations.
