ABSTRACT
This chapter deals with a preliminary test for the definition of slow-moving landslide activity indicators by the joint use of Differential Interferometric Synthetic Aperture Radar (DInSAR) data and landslide-induced damage to properties. It analyses the DInSAR mean deformation velocities as state of activity indicators of slow-moving landslides and, compared with data derived from damage to properties analysis. The ground displacements, detected via low-resolution DInSAR data, and the available damage database point out that the DInSAR technique, if adequately supported by in-situ surveys, seems to be a valuable perspective for the landslide activity assessment. The technique is designed to exploit both the advantages of Permanent Scatterers (PS)-based and more classical multipass DInSAR analysis based on stacking of interferograms, which have been developed after the PS technique. The comparison underlines that low-resolution DInSAR pixels are able to single out the moving landslide affected areas but more detailed studies are necessary for them to be properly characterized.
