CHEROKEE, Okla. (AP) — An earthquake has shaken parts of northern Oklahoma near the Kansas border.
The U.S. Geological Survey says the 3.1 magnitude temblor was recorded at about 4 a.m. Tuesday about eight miles northeast of Cherokee in Alfalfa County. Cherokee is about 15 miles south of the Kansas border and 130 miles northwest of Oklahoma City.
The earthquake occurred at a depth of about four miles. No damage or injuries was immediately recorded. Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and damage is not likely from earthquakes below magnitude 4.0.
The Oklahoma Geological Survey has said it is likely that many recent earthquakes in the state are being triggered by the injection of wastewater from oil and natural gas drilling operations.
