September 04, 2014Ten years ago, hydraulic fracturing barely existed. Today 45,000 fracked wells produce natural gas, providing energy for millions of homes and businesses, and nearly a quarter of the nation’s electricity. But scientists are far behind in understanding how this boom affects people near wells. Geochemists Beizhan Yan and James Ross of Columbia University’s Lamont-Doherty Earth Observatory are trying to fill in this gap in rural northeastern Pennsylvania, where thousands of fracking operations have taken over formerly quiet hilltops, farms and back roads.

Earthquakes that have shaken an area just outside Youngstown, Ohio in the last nine months—including a substantial one on New Year’s Eve—are likely linked to a disposal well for injecting wastewater used in the hydraulic fracturing process, say seismologists at Columbia University’s Lamont-Doherty Earth Observatory who were called in to study the quakes.
