InSAR Uncertainty Due to Orbital Errors

LOS velocity across the southern San Andreas fault system from InSAR compared with GPS observations.

The Seismology and Geodesy Lab (SGL) at the UM Rosenstiel School is using seismological  and space-geodetic methods  to conduct research on active processes under and above the Earth's surface. The techniques used include seismic tomography and earthquake relocations, Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning Systems.

The research topics include active volcanoes, active tectonics, changes of the global ice masses, hydrology and vegetation. The SGL state-of-the-art research techniques include: Seismic tomography and earthquake relocation, Synthetic Aperture Radar (SAR), Interferometric Synthetic Aperture Radar (InSAR), Global Positioning System (GPS), and Ground-based Light Detection and Ranging (LiDAR).
