Michael Behar at Mother Jones says the oil and gas industry is trying to stay quiet regarding the link between injecting frack wastewater deep underground and the increase in earthquakes in the areas around the injection sites.
Behar: "Operators are injecting more water than ever into drilling wells, while boring new wells to accommodate the overflow. Yet nobody really knows how all this water will impact faults, or just how big an earthquake it could spawn. In the West, small quakes don't often cause much damage because of stricter seismic regulations but also because the underground formations—buckled, with younger rock—absorb all but the biggest events. Induced quakes, however, are happening primarily in flatter states, amid more rigid rock, making them more destructive—a stone makes a bigger splash when it's hurled into a glassy pond than a river of raging whitewater."
