The temblor caused power outages for more than 4,600 electricity customers in north Edmond.
Power was restored about an hour later.
The city of Edmond says power has been restored to two electric substations after a magnitude-4.2 natural disaster rattled the area.
Oklahoma, August3:An quake registering 4.2 on the richter scale in central Oklahoma, US, damaged power supply lines, disrupting supply to hundreds of customers.
More than an hour after the quake, nearly all customers had their power restored.
The Induced Seismicity Department at the Oklahoma Corporation Commission (OCC) and the Oklahoma Geological Survey (OGS) are investigating the latest quake activity in the Edmond area.
Seismologists and state officials have said an increase in the frequency of quakes over the past few years in Oklahoma has been tied to the disposal of wastewater from fracking.
Skinner also notes there's a fault line in the area. "There are no Arbuckle disposal wells at or very close to the location".
The OCC added that a field inspector from its Oil and Gas Conservation Division (OGCD) has checked Arbuckle wells within a 10-mile radius of the natural disaster activity, and that recent data on the disposal wells' operations were being reviewed by the commission. A statement from regulators, published by local KWTV News 9, said investigators were on the ground near the cluster of tremors in the Edmond area.
