Ground-based SAR interferometry as a tool for landslide monitoring during emergencies

This work concerns the application of ground-based synthetic aperture radar (GB-SAR) interferometry as a tool for the landslide monitoring during emergencies. An example of application of this technique to the Cortenova landslide, Italian Alps, is described. The deformation maps provided by GB-SAR interferometry allows for the study of the landslide temporal evolution and the volume estimation of the material involved in the mass movement. This information is important for the assessment of future risk scenarios needed to draw up the emergency plans for civil protection purposes.
