Fig. 4: InSAR-derived subsidence before the Ridgecrest earthquake.

a Pre-seismic (01/02/2015–07/04/2019) vertical InSAR displacement rate. Ascending and descending InSAR imaging geometry (i.e., flight direction and line-of-sight (LOS) is shown on the right. b Locations of injection and extraction wells (downward-facing and upward-facing triangles, respectively) relative to surface ejecta (gray areas). The green area indicates the ___location of the control group pixels, where there is no mining prior to the Ridgecrest earthquake. c Full InSAR time series showing vertical displacement for pixels that coincide with the unmined area (green) and the phase 1 and 2 injection wells (dark purple and dark orange, respectively), where symbols indicate the mean value and shaded regions indicate the standard deviation for each category. d Full InSAR time series for phase 1 mining injection wells (dark purple) and extraction wells (light purple).
