State Links Earthquakes, Fracking
State geologists believe they have for the first time linked earthquake activity in the Utica shale formation to fracking, and the state says it is issuing new permit conditions in seismic-sensitive areas. State Oil & Gas Chief Rick Simmers tells The Associated Press a state investigation of five small tremors in the Youngstown area last month has found a probable link. He says Ohio is setting new permitting conditions in earthquake-sensitive areas and has halted drilling indefinitely at the site of the March quakes. A seismologist with the U.S. Department of Interior says it's the first time a link has been drawn between seismic activity and fracking taking place in the Marcellus-Utica shale across the northeastern United States.
