Fig. 2. LOS deformation velocity (descending) 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) LOS velocity from gpsgridder [Sandwell
& Wessel , 2016] projected into the LOS (for illustration purposes
only). b) Velocity variation/uncertainty is the deviation of the time
series at each pixel from a linear regression fit. The velocity
discontinuities between swaths are due to the change in look angle. d)
Semi-vertical velocity is the LOS with horizontal velocity model
[Zeng & Shen , 2017] removed. The triangles in d) mark the
location of GNSS stations plotted in Fig 4b (black) and Fig 4c (gray).
