A 4.0 magnitude earthquake in Ohio on New Year's Eve did not occur naturally and may have been caused by high-pressure liquid injection related to oil and gas exploration and production, an expert hired by the state of Ohio said on Tuesday.
Ohio's Department of Natural Resources on Sunday suspended operations at five deep well sites in Youngstown, Ohio, where the injection of water was taking place, while they evaluate seismological data from a rare quake in the area.
