Fracking: More Destructive Than You Ever Thought

David Dayen of FDL gives us this from CNN:

Fracking Linked to Earthquakes in Ohio; Wells Indefinitely Shut Down

Four fracking wells in northeastern Ohio have been shut down by the state, after an increase in seismic activity, which many believe has been caused by the fracking itself.

Ohio Department of Natural Resources Director James Zehringer had announced on Friday that one such well — which injects “fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer,” the U.S. Environmental Protection Agency explains — was closed after a series of small earthquakes in and around Youngstown.

Then on Saturday, a magnitude 4.0 earthquake struck that released at least 40 times more energy than any of the previous 10 or more tremors that had rattled the region in 2011.

[Dayen again…] This is not the first time that fracking has been linked to earthquakes. Earlier this year, unusual earthquakes in Oklahoma were seen by many as helped along by fracking. The scientific consensus on that incident was that fracking can cause small tremors, but nothing of the scale as seen in Oklahoma, which did follow a natural fault line.

Ohio is not the first state that comes to mind when you think of earthquakes. And Dayen also points out

… The frequency of the quakes is definitely unusual; there have been 11 in the past eight months within two miles of the wells.

Eleven in eight months… in a state not known for earthquakes. How likely is that to be an innocent coincidence?
