The third in a string of earthquakes south of Wilson occurred early Tuesday.
The quake occurred at 11:29 a.m., 6.8 miles south of Wilson and reached a 3.4 on the Richter scale, making it the third quake felt in Wilson in 30 days. The first quake occurred September 26 and reached a 3.1 on the Richter scale, the third quake, a 3.1, hit at 7:47 a.m. on October 21, 4.9 miles southwest of Wilson, according to the United States Geological Survey.
Wilson Mayor Frank Schaaf said the quakes were felt in the city, but there was no significant damage as a result.
“It’s cracked some sheet rock, but that’s about it,” Schaaf said.
The quakes resulted in the Oklahoma Corporation Commission shutting down a disposal well located south of Wilson. The well is operated by Postoak Disposal LLC, a company based in Houston, Texas.
Oklahoma Corporation Commission Spokesperson Matt Skinner said the well was shut down as of Saturday, days before Tuesday’s quake.
“They have to shut down because there has been seismatic activity,” Skinner said. “The order is quite clear.”
Skinner said when the company applied for a permit for the disposal well, the agreement included language that specified the well would have to cease operating if the area experienced seismic activity. Skinner said the permit doesn’t call for anyone to prove the seismic activity is linked to the well.
