Groundwater Depletion Is Destabilizing the San Andreas Fault and Increasing Earthquake Risk – May 15, 2014
New Research also links seasonal water levels to seasonal patterns in seismicity
By Katherine Bourzac
Depletion of groundwater in the San Joaquin Valley is having wide-ranging effects not just on the agricultural industry and the environment, but also on the very earth beneath our feet. Massive changes in groundwater levels in the southern Central Valley are changing the stresses on the San Andreas Fault, according to research published today.
Researchers have known for some time that human activity can be linked to localized seismic effects. In particular, much of the debate about fracking in California in the past few years has centered on evidence that the process of injecting large volumes of liquid underground can lubricate fault lines and increase local earthquake risk.… more
