The Oklahoma Corporation Commission has directed dozens of wastewater disposal wells within an approximate 500-square-mile radius of the epicenter the Oklahoma earthquake to shut down.

The commission says about 35 wells are included in the directive, which was issued following the 5.6 magnitude earthquake that struck Saturday morning about nine miles northwest of Pawnee in north-central Oklahoma.

The number of magnitude 3.0 or greater earthquakes has skyrocketed in Oklahoma, from a few dozen in 2012 to more than 900 last year.

Commission spokesman Matt Skinner says the wells were directed to shut down due to scientific links that the increase to the underground disposal of wastewater from oil and gas production induces earthquakes. The commission has previously asked producers to reduce wastewater disposal volumes.

The earthquake ties the record for the strongest earthquake in recorded Oklahoma history. No major damage was reported, and there was one minor injury.

BROWNVILLE, Neb. (AP) — The Latest on the large earthquake in Oklahoma (all times local):

1:20 p.m.

Officials at a nuclear power plant in the southeast corner of Nebraska say tremors from the Oklahoma earthquake were felt at the plant.

Nebraska Public Power District’s Cooper Nuclear Station south of Brownville declared an “unusual event” just after 7 a.m. because of the minor tremors.

Officials say there was no damage to the plant or equipment, and no threat to the public or plant personnel occurred. The plant continued operating Saturday, but station personnel increased monitoring of plant equipment, per the plant’s policy.

Station emergency preparedness manager Jim Stough says the nuclear station was built to withstand some earthquakes and other scenarios that are likely to occur in the region.

Officials say local, county, state, and federal agencies were notified of the event.
