A strong 5.1 magnitude earthquake rattled Oklahoma shortly before 11:30 p.m. Friday. The epicenter was located near Prague, about 60 miles southwest of Tulsa.
The shaking could be felt statewide including in Oklahoma City and Tulsa, according to the Oklahoma Geological Survey.
OGS said Oklahomans should expect strong aftershocks in the coming weeks.
A 5.7 magnitude earthquake hit nearly the same area in 2011. That event was linked to oil and gas wastewater disposal activities.
Officials say it's possible Friday night's quake could be linked to injecting wastewater from fracking in the area.
The Oklahoma Corporation Commission is issuing a directive to shut down all disposal wells into and within 10 miles of the Arbuckle Mountains by Feb. 17.
OCC says the gradual shutdown process is necessary to avoid sudden pressure changes that could result in more seismic activity.
The commission says the order to shut down all disposal wells within the vicinity is an initial response. Further study may result in new directives.
No significant damage was reported from Friday night's earthquake.
