Earthquake Outbreak in U.S. Tied to Fracking Wastewater

Thursday, April 12, 2012

April 12 (Bloomberg) -- A spate of earthquakes across the middle of the U.S. is "almost certainly" man-made, and may be caused by wastewater from oil or gas drilling injected into the ground, U.S. government scientists said in a study.

Researchers from the U.S. Geological Survey said that for the three decades until 2000, seismic events in the nation's midsection averaged 21 a year. They jumped to 50 in 2009, 87 in 2010 and 134 in 2011.
Those statistics, included in the abstract of a research paper to be discussed at the Seismological Society of America conference next week in San Diego, will add pressure on an energy industry already confronting more regulation of the process of hydraulic fracturing.

"Our scientists cite a series of examples for which an uptick in seismic activity is observed in areas where the disposal of wastewater through deep-well injection increased significantly," David Hayes, the deputy secretary of the U.S. Department of Interior, said in a blog post yesterday, describing research by scientists at the U.S. Geological Survey.    READ MORE

  2. America isn't concerned. Now if a crack in the crust opens and floods the breadbasket with lava... Then that will signal it's time to begin debating the issues involved. Not before, because that's paranoia. Can't let paranoia get in the way of profits now can we? That would not be rational!
