Exploration Basis
To determine ground subsidence using satellite radar interferometry
Interferometric synthetic aperture radar (InSAR) data collected in the Coso geothermal area, eastern California, during 1993-1999 indicate ground subsidence over a approximately 50 km 2 region that approximately coincides with the production area of the Coso geothermal plant. The maximum subsidence rate in the peak of the anomaly is approximately 3.5 cm yr -1 , and the average volumetric rate of subsidence is of the order of 10 6 m 3 yr -1 . The radar interferograms reveal a complex deformation pattern, with at least two irregular subsidence peaks in the northern part of the anomaly and a region of relative uplift on the south.
