On Shaky Ground

CALIFORNIANS AT RISK OF QUAKES CAUSED BY FRACKING WASTEWATER DISPOSAL

 

By Miriam Raftery

March 16, 2014 (California)--A new report reveals that the risk of earthquakes in California is being dramatically increased by oil companies injecting billions of gallons of wastewater from fracking, or hydraulic fracturing, into disposal wells near active faults near major cities.  “Millions of Californians live in areas at risk for induced earthquakes,” the report concludes.

The report, titled “On Shaky Ground,” was prepared by Earthworks, the Center for Biological Diversity, and Clean Water Action.   It found that 54% of our state’s 1,553 injection wells are within 10 miles of a recently active fault, 23% are within five miles and 6% are within just one mile. 

Numerous earthquakes across the country have been linked to fracking by scientists, including temblors as high as 5.7 on the Richter scale, the report details. Fracking quakes are common in areas such as Oklahoma and Texas, producing quakes higher than ever seen in some places.
