LUTHER, Okla. – The U.S. Geological Survey has recorded at 4.1 magnitude earthquake in the Oklahoma City area.
The quake struck at 10:44 a.m. Wednesday near Luther, about 30 miles north of Oklahoma City.
No injuries or damage have been reported, but the USGS website shows the earthquake was felt 135 miles away in Wichita, Kansas.
The USGS also recorded a 2.8 magnitude quake at 6:31 a.m. near Harrah, about 25 miles northeast of Oklahoma City.
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.
