The shaking doesn’t actually come from the high-pressure fracking itself, but from the injection of tons of post-frack dirty wastewater into disposal wells. Only Ohio requires a risk assessment for quakes around the state’s injection wells. Mother Jones digs into this story , speaking with numerous scientists who agree: Frack the earth and it will frack you back. “There is no shortage of evidence,” writes reporter Michael Behar. Between 1972 and 2008, the USGS recorded just a few earthquakes a year in Oklahoma. In 2008, there were more than a dozen; nearly 50 occurred in 2009. In 2010, the number exploded to more than 1,000.
