The California Institute of Technology (Caltech), Postdoctoral Scholars Program at the Jet Propulsion Laboratory (JPL) invites applications for a postdoctoral research position for imaging and modeling crustal deformation using space geodesy.
Space geodetic measurements such as InSAR and GPS provide capability to image crustal deformation processes at various spatiotemporal scales. Data acquisitions from multiple satellite SAR sensors (e.g, ERS, Envisat, ALOS, Radarsat, TerrarSAR-X, Cosmo-SkyMed, Sentinel-1A/B etc.) now allow us to image time-variable deformation with fine spatial resolution over different time scale. The airborne UAVSAR has been acquiring data along the San Andreas Fault system and captured a spectrum of deformation signals associated with fault creep/locking, earthquake and anthropogenic sources, and landslide.
Integration of InSAR and GPS allows noise reduction and reveals deformation signals that are otherwise not possible. These deformation measurements can be combined with numerical modeling to better constrain fault/volcano source parameters, mechanical and rheological properties, and lead to improved understanding of earthquake and volcano source processes, strain accumulation, transient fault slip, and postseismic deformation.
