Title: Continental-Scale Earth Observation with InSAR: From Plate Boundaries to Groundwater Depletion

Advances in satellite radar interferometry have made it possible to systematically monitor surface deformation across continents. Central to this progress is the COMET-LiCSAR automated processing system and open-access portal, which has enabled large-scale, consistent generation of Sentinel-1 InSAR time series. In this talk, I present two key applications made possible by this infrastructure: a trans-continental strain and velocity field for the Alpine-Himalayan Belt, and a country-wide assessment of land subsidence linked to groundwater depletion in Iran. By integrating LiCSAR-derived displacement data with GNSS observations and applying time-series analysis techniques, we reveal both tectonic and anthropogenic deformation patterns with high spatial and temporal resolution. These examples highlight how open, automated InSAR processing platforms can support geohazard research and environmental monitoring at regional to continental scales.
