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.

Yesterday, five local residents settled for an undisclosed sum of money after suing two oil companies. Those five residents aren't the only ones suing Chesapeake Energy and BHP Billiton. Twenty other residents are expecting to file lawsuits in Arkansas state court, according to Reuters.
