Regardless of how regulators resolve their investigation into an April 2 earthquake in southeastern Ohio, drilling and well operators in the area will almost certainly need to do more careful monitoring and reporting in the future, now that there’s a known seismic risk. “Any time an earthquake occurs, that’s an indication that there’s a fault there,” said geologist Michael Brudzinski at Miami University in Oxford.The magnitude 3.0 quake on April 2 took place at 7:58 a.m. in the Marietta unit of Wayne National Forest in southeastern Ohio. “We hadn’t really seen [an earthquake] in the area where this one occurred” in April, with the exception of the two events of magnitudes of 2.3 and 1.8 on December 12, 2016, Brudzinski noted.Nearby oil and gas activities are on hold pending further investigation by the Ohio Department of Natural Resources.
