Geologists say a 3.2 magnitude earthquake has rattled parts of central Oklahoma.
The U.S. Geological Survey says the earthquake was recorded at 10:27 a.m. Monday about 12 miles northeast of Crescent in Logan County, about 39 miles north of Oklahoma City.
The earthquake was recorded at a depth of about three miles and no damage was immediately reported. Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest 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 closure of some wastewater disposal wells and asked producers to reduce disposal volumes in earthquake-prone regions of the state.
