Fracking Wastewater Disposal Seen Linked to Earthquakes

Disposing of wastewater from hydraulic fracturing may make fault zones more prone to earthquakes, according to researchers from Columbia University and the University of Oklahoma.

The researchers found a “profound” increase in the number of earthquakes at three sites where fluids from energy production were injected into the ground, said Nicholas van der Elst, a scientist at Columbia’s Lamont-Doherty Earth Observatory in Palisades, New York, and lead author of an article published today in the journal Science.
