Ground deformations above wastewater injection wells may be tipoff.
Radar data gathered by a Japanese satellite provides evidence that injecting wastewater from fracking into deep wells near Timpson, Texas, caused the ground to deform, and led to a magnitude 4.8 earthquake that shook the area back in May 2012.
The study, published in the journal Science on Sept. 23, found that the disposal of fracking wastewater put pressure on rocks and caused the ground to lift, up to nearly 5 miles from the well sites.
