Integration of DInSAR and Multi-Source Data for the Multi-Scale Management of Built-Up Areas Exposed to Slow-Moving Landslide Risk

The integration of Differential Interferometric Synthetic Aperture Radar (DInSAR) displacement data with ground-based monitoring and ancillary multi-source information (deriving from geological-geomorphological-geotechnical analyses and damage surveys to the built-up environment) can nowadays provide a useful support to activities pursuing the management and protection of structures (e.g., buildings) and infrastructure (including roads, bridges, embankments) exposed to slow-moving landslide risk. Indeed, the implementation of the most suitable risk mitigation strategies requires appropriate procedures tailored on the quality and quantity of available datasets and their joint use according to the scope and the related scale of analysis. As a result of a 15-year multidisciplinary joint research activity, this paper presents a multi-scale methodology which is applied to buildings affected by slow-moving landslides located in selected areas of the Cosenza Province (Calabria region, southern Italy).
