Could Fracking be to Blame for Quakes in Ohio?
It was recently published in Scientific American, the winner of the 2011 National Magazine Award for General Excellence, that the fracking itself is not the cause of the repeated quakes, but rather it's possible that the disposal of fracking wastewater into wells is the culprit.
Because of the close proximity of the quakes to a wastewater injection site, the Ohio Department of Natural Resources had mobile seismographs installed in the vicinity of the quakes.
The seismographs revealed, with 95 percent certainty, that the last two earthquakes were within 100 meters of each other.
Additionally, they both placed within 0.8 kilometers of the injection well and at roughly the same depth as the fault that caused the quakes.
Youngstown, Ohio, tends to be seismically inactive, but it's friction that keeps the faults from moving, AccuWeather Expert Senior Meteorologist Jim Andrews said.
"By injecting fluid underground, existing faults may be unlocked."
