4.0 earthquake strikes Ohio – “related” to fracking
January 1, 2012
(AP) — Officials said Saturday they believe the latest earthquake activity in northeast Ohio is related to the injection of wastewater into the ground near a fault line, creating enough pressure to cause seismic activity.
The brine wastewater comes from drilling operations that use the so-called fracking process to extract gas from underground shale. But Ohio Department of Natural Resources Director Jim Zehringer said during a news teleconference that fracking is not causing the quakes.
“The seismic events are not a direct result of fracking,” he said.
