Jeffrey Dick, chairman of Youngstown State University's geology department, talks with Bloomberg's Mark Niquette about the possibility that hydraulic fracturing may be causing earthquakes around Youngstown, Ohio.
Fracking is a process of blasting sand, water and chemicals into shale to extract natural gas. Earthquakes didn't happen around the city until D&L Energy Inc. began injecting wastewater from drilling into a 9,300-foot disposal well in December 2010. (Source: Bloomberg)
