"Evaluation of interferometric synthetic aperture radar (InSAR) techniques for measuring land subsidence and calculated susidence rates for the Escalante Valley, Utah, 1998 to 2006" . . . . . . . . . . . "Previous studies have shown the Escalante Valley, Utah, is subsiding due to groundwater withdrawal. The magnitude and spatial pattern of this cm/yr.-scale subsidence is mapped with satellite data from a synthetic aperture radar (SAR) using interferometric SAR (InSAR) processing techniques." . .
