For the First Time, Scientists Prove Fracking Caused an Earthquake Strong Enough to Be Felt by People
A series of 77 earthquakes in Ohio — including one strong enough to be felt by humans — was caused by the controversial process of hydraulic fracturing, scientists claimed in research published Tuesday in the Bulletin of the Seismological Society of America (BSSA).
Small earthquakes have been attributed to fracking in Ohio before. But those earthquakes were all too small to be felt. Tuesday’s study is the first time scientists have attributed a larger earthquake to fracking, the process of injecting high-pressure water, sand and chemicals underground to crack shale rock and let gas flow out more easily.
