Production-Induced Subsidence at the Los Humeros Geothermal Field Inferred from PS-InSAR

Figure 5

Deformation maps showing the mean velocities in the satellite line of sight (LOS) in mm/year (a) without tropospheric correction and (b) corrected for topography-related tropospheric phase delays. Movements are relative to the mean of the whole area. Negative values indicate movement away from the satellite (~subsidence) and positive values indicate movement towards the satellite (~uplift). The black rectangle in (a) highlights the region used to calibrate the tropospheric corrections.
