Tectonic contraction across Los Angeles after removal of groundwater pumping effects.

Focuses on a study that augmented the global positioning system (GPS) data with interferometric synthetic aperture radar imagery to take into account the deformation associated with groundwater pumping and strike-slip faulting in Los Angeles, California. Overview of the data on the anthropogenic deformation in the area; Information on the GPS sites on the Santa Ana basin which is located in the area; Velocities measured in the GPS sites.
