Pennsylvania to release probe results on quakes, fracking

Pennsylvania environmental regulators are set to release the findings of their investigation into a series of minor earthquakes that took place near fracking operations by an oil and gas company



HARRISBURG, Pa. (AP) — Pennsylvania environmental regulators are set to release the findings of their investigation into a series of minor earthquakes that took place near fracking operations by an oil and gas company.

The quakes were recorded last April about 50 miles north of Pittsburgh and three-quarters of a mile from a natural gas well owned by Houston-based Hilcorp Energy Co. They were too weak to be felt by humans and no damage was reported.

The state Department of Environmental Protection is presenting its findings on Friday. DEP notes the quakes had a “marked ... relationship” to Hilcorp’s drilling operation in terms of timing and location.

Fracking, a method to extract gas or oil from underground shale, has been tied to earthquakes in neighboring Ohio and other states, but never in Pennsylvania, the nation’s No. 2 natural gas-producing state.
