State regulators and scientists should make a determination by the end of the week whether an earthquake in northeast Ohio on Sunday has any connection to nearby injection wells.
The Ohio Department of Natural Resources and scientists from Columbia University are studying the cause of the 2.1-magnitude quake centered in Weathersfield, near Youngstown.
Two injection wells for the disposal of wastewater from oil and gas drilling had received permission to operate nearby in March. The ODNR said one of the wells recently received permission to increase its pressures.
The citizens group Frackfree Mahoning Valley called for an immediate halt to deep injection at the wells. It plans a public meeting Wednesday
