2 More Fracking-Related Earthquakes Hit Oklahoma Despite New Rules Meant to Prevent Them
Two earthquakes registering at a 4.5 and a 4.4 magnitude shook frack-happy Oklahoma on Saturday, some of the strongest felt in the state this year. The stronger quake occurred just a few miles from the city of Cushing, which holds one of the largest crude oil storage facilities in the world.
The recent quakes struck only a handful of weeks after the Oklahoma Corporation Commission (OCC), the state’s public utilities commission, shut down several disposal wells around Cushing and issued new regulations meant to prevent more earthquakes in the area, according to Al Jazeera.
A local report said that the stronger 4.5 magnitude quake occurred around 5 p.m. Saturday evening and could be felt in the nearby cities of Stillwater, Guthrie, Sapulpa, Oklahoma City and other parts of the metro. There were multiple aftershocks in Cushing, recorded at 3.0, 3.2, 3.1, 2.8, 2.7 and 2.5.
Bob Noltensmeyer, Cushing Emergency Manager, told the Associated Press he had not received reports of significant damage in the area although there were “shattered nerves.”
“This one was pretty strong,” he added. “The whole house shook.”
A 4.4 was also recorded on Saturday at 4:20 a.m. about 18 miles southwest of Medford and about 100 miles northwest of Cushing.
America’s heartland used to register earthquakes from two a year to almost two a day. This year, roughly 700 earthquakes of magnitude 3 or higher has shook the state, compared to 20 throughout 2009, as the Associated Press pointed out.
The Sooner State’s seemingly never-ending earthquakes appear to be a man-made side effect of the country’s drilling boom. Scientists say that the injection of wastewater byproducts into deep underground disposal wells from fracking operations are very likely triggering the major increase of seismic activity in Oklahoma, which is not near any major fault lines.
