OKLAHOMA CITY — The 37 wastewater disposal wells to be shut down in north-central Oklahoma, where a 5.6 magnitude earthquake struck this weekend, are just a fraction of the state’s total number.
There are about 4,200 total wells across the state and about 700 in a 15,000-square-mile “Area of Interest” created by the commission to address earthquakes in the area that includes the epicenter of Saturday’s temblor near Pawnee.
