See What 1,000 Tiny, Fracking-Caused Earthquakes Can Do to a Home
Yet another reason to worry about fracking.
In 2010 and 2011, there were as many as 1,000 minor earthquakes in Arkansas. And scientists believe they were caused by fracking.
Seismologists at the U.S. Geological Survey say the disposal of millions of gallons of wastewater flowback as part of the fracking process can create "micro earthquakes," which are rarely felt, and also the rare larger seismic disruption. Scientists say that's what happened in Greenbrier, Arkansas, where the quakes damaged homes.
