Title: Uplift and seismicity driven by groundwater depletion in central California
Abstract: Vertical GPS rates spanning central California show modest uplift of Sierra Nevada and Coast Range mountains, as well as rapid subsidence of the San Joaquin Valley. Elastic modeling demonstrates that loss of groundwater in the valley leads to flexural uplift of the valley, and may change the stress state surrounding the San Andreas Fault. As such, we highlight a new and potentially important link between human activities and solid earth deformation.
