Study Suggest Depleting Groundwater Increases California Quake Risk (May 13, 2015)
According to a study published online in the journal Nature, temblor frequency seems on the upswing in Central California because of groundwater depletion. As water tables drop, land subsides accordingly and the earth’s crust underlying the valley and its environs begins to rise. This pushes the surrounding coast range and Sierra Nevada skyward.This landscape-scale rebound relaxes the downward tension of the San Andreas Fault, likely increasing the risk of quakes.



UC San Diego Speeds Up Simulations (May 13, 2015)
