USGS reports magnitude 3.1 earthquake recorded near Perry

Posted September 18

— The U.S. Geological Survey reports a 3.1 magnitude earthquake has been recorded near Perry in north-central Oklahoma.

The earthquake was recorded at 1:30 p.m. Sunday. No injuries or damage were reported.

The area is about 55 miles north of Oklahoma City.

Geologists say earthquakes of magnitude 2.5 to 3.0 are general they smallest that are felt by humans and damage is not likely in quakes below magnitude 4.0.

An increase in magnitude 3.0 or greater earthquakes in Oklahoma has been linked to underground disposal of wastewater from oil and natural gas production. State regulators have ordered the shutdown of some wastewater disposal wells and asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state.
