SAN FRANCISCO— Oil companies are increasing California’s earthquake risk by injecting OnShakyGroundbillions of gallons of oil and gas wastewater a year into hundreds of disposal wells near active faults around Los Angeles, Bakersfield and other major cities, according to a new report from Earthworks, the Center for Biological Diversity and Clean Water Action.

A boom in hydraulic fracturing (“fracking”) in California would worsen the danger of earthquakes, the report found, by greatly increasing oil wastewater production and underground injection. Extracting the Monterey Shale’s oil could produce almost 9 trillion gallons of contaminated wastewater, which could expose California to a surge in damaging earthquakes like those seen in Oklahoma, Texas and other states experiencing rapidly increased fracking and wastewater production.
