OKLAHOMA CITY (AP) – Two earthquakes have rattled parts of northern Oklahoma.
The U.S. Geological Survey says a 3.3 magnitude earthquake was recorded at 12:53 p.m. Monday about 17 miles west-southwest of Perry in Garfield County and a 3.0 magnitude quake was recorded in the same area two minutes later.
No damage or injuries were immediately reported. Geologists say damage is not likely in earthquakes below magnitude 4.0 and that earthquakes of magnitude 2.5 to 3.0 are the smallest that can be felt by humans.
Scientists have linked an increase in magnitude 3.0 or greater earthquakes in Oklahoma to the underground disposal of wastewater from oil and natural gas production. State regulators have asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state.
