Fracking in Ohio Causing Earthquakes

“A dozen earthquakes in northeastern Ohio were almost certainly induced by injection of gas-drilling wastewater into the earth, Ohio oil and gas regulators said Friday as they announced a series of tough new regulations for drillers.

…

“The report’s findings, the Ohio regulator said, show the earthquakes were based on “a number of coincidental circumstances.” For one, investigators said, the well began operations just three months ahead of the first quake.

They also noted that the seismic activity was clustered around the well bore, and reported that a fault has since been identified in the Precambrian basement rock where water was being injected.
