Seasonal GPS Vertical Motions Related to Groundwater Extraction May Enhance Seismicity on San Andreas Fault System Article


  • Analysis of GPS stations, many that are part of the Plate Boundary Observatory, reveals uplift of the California Coast Ranges and Sierra Nevada Mountains. Much of this uplift comes from groundwater depletion for irrigation. These changes may increase the rate of seismicity on the San Andreas Fault.
