CHICKASHA, Okla. — No injuries were reported after a 3.0 magnitude earthquake shook parts of central Oklahoma.
The U.S. Geological Survey says the quake was reported at 12:08 p.m. Tuesday about 7 miles (12 kilometers) north-northeast of Chickasha, about 37 miles (60 kilometers) southwest of Oklahoma City. The temblor was recorded at a depth of about 8 miles (12 kilometers).
No damage was immediately reported. Geologists say damage is unlikely in temblors below magnitude 4.0.
Thousands of earthquakes recorded in Oklahoma in recent years have been linked to the underground injection of wastewater from oil and gas production.
Geologists say about 200 magnitude 3.0 or stronger quakes were recorded in Oklahoma last year, down from 302 in 2017 and the third consecutive year of declines since regulators ordered producers to close some wells.
