Space-borne Interferometric Synthetic Aperture Radar (InSAR) has developed rapidly over the past 20 years and has now become one of the most preferred geodetic methods for the study of a variety of natural and geological hazards. Our capabilities for hazard monitoring have been further enhanced thanks to the high-resolution X-band radar data provided by the German TerraSAR-X satellite. Time-series InSAR using X-band data with short-revisit and regular schedule makes the long-term monitoring of small displacement with millimetre precision more feasible. In this study, we present a brief overview of some findings and results obtained in several case studies where we used X-band InSAR observations to investigate dynamic deformation associated with earthquake cycle and postseismic processes, subsurface fluid flow, landslide, glacial processes, and engineering structures.
