At least three earthquakes, the largest at 4.1 magnitude shook northern Oklahoma Sunday evening.
So far, there are no reports of injuries or damage.
The U.S. Geological Survey recorded the quakes around 5:30 p.m. and their epicenters were located a few mile east of the community of Nescatunga in Alfalfa County. The weakest of the earthquakes was recorded at 3.1 magnitude.
A spokesman for the Oklahoma Corporation Commission indicated the quakes and their area of impact are “under review” by regulators.
In the past, some quakes resulted in the curtailment or reduction of wastewater well activity in the region ordered by the commission.
