Mountain regions are especially prone to the increasing impact of mass-movement processes. Anthropogenic forced climate change increasingly triggers landslides due to changes in precipitation occurrence and magnitude and hence in pore-water pressure. This endangers valley-confined infrastructure and livelihoods. With respect to two case studies, the advantages and limitations of an additional application of satellite-based interferometry synthetic aperture radar (SB-InSAR) data to the existing methods, such as laser scanning (LiDAR), photogrammetry, differential global navigation systems (DGNSS), electric resistivity tomography (ERT), seismic and inclinometer measurements, are discussed. SB-InSAR data exists since 1992 and covers nearly the whole globe. Depending on the mean displacement rates of landslides, SB-InSAR data can be used to monitor surface deformations. As the case studies “Reissenschuh” and “Padauner Berg” in Tyrol will show, the complementary usage of SB-InSAR data enhances process delineation, provides additional data coverage in remote areas and a high temporal resolution due to repeated measurements every five days.
