A new study suggests that the heavy use of ground water for pumping and irrigation is causing mountains to lift and valleys to subside. The scientists say this depletion of the water is increasing seismic activity along the San Andreas fault. They worry that over time this will hasten the occurrence of large quakes. The report has been published in the journal Nature. The...
