FAIRVIEW, Okla. (AP) — An earthquake has shaken parts of northern Oklahoma.
The U.S. Geological Survey says the 3.5 magnitude quake was recorded at 8:06 a.m. Sunday about 16 miles northwest of Fairview in Major County, about 100 miles northwest of Oklahoma City. The temblor was recorded at a depth of three miles.
No injuries or damage were immediately reported. Geologists say damage is not likely in quakes below magnitude 4.0.
The number of magnitude 3.0 or greater earthquakes in Oklahoma has risen from a few dozen in 2012 to more than 900 last year.
Scientists have linked the increase to underground disposal of wastewater from oil-and-gas production. State regulators are asking oil and gas companies to reduce their wastewater disposal wells.
