"Environmental activist Erin Brockovich is helping Oklahoma's Pawnee Nation take on several fracking companies in a lawsuit alleging that damages to its tribal buildings and reservation property was the result of man-made, or induced, earthquakes.

National Geographic reports that the Native American tribe has retained the law firm Weitz & Luxenberg, with the aid of Brockovich, to sue Eagle Road Oil LLC, Cummings Oil Company, and 25 other oil and gas companies.

In September 2016, a magnitude 5.8 earthquake—the state's largest ever recorded—struck near the town of Pawnee. The tribe alleges that wastewater injected into wells operated by the defendants caused the record-breaking quake and is seeking damages to real and personal property, market value losses, as well as punitive damages."
