Fig. 3 . LOS deformation velocity (ascending) along the San Andreas fault system. a) Total LOS deformation velocity with red color denoting motion toward the satellite and blue away from the satellite. A second color scale is added to highlight the major subsidence in the Central Valley. b) Velocity variation/uncertainty derived from linear regression on the resulting time-series. c) LOS velocity from gpsgridder [Sandwell & Wessel , 2016] projected into the LOS (for illustration purpose only).
