"The Oklahoma Supreme Court ruled Tuesday that a woman injured in a 2011 earthquake can file suit in district court against the two energy companies she accuses of causing the quake.

The ruling raises the prospect of more lawsuits seeking to hold companies responsible for an increase in seismic activity in the state, as more scientific studies link the tremors to the energy industry. In particular, the studies have found evidence tying quakes to operations that inject wastewater left over from drilling into wells deep underground.

Sandra Ladra of Prague, Okla., about 60 miles east of Oklahoma City, sued New Dominion LLC and Spess Oil Co. last summer for injuries she sustained during a 5.6-magnitude quake that toppled her stone chimney. The lawsuit in Lincoln County District Court contends that the companies caused the quake by injecting wastewater into nearby wells."
