Abstract

In the present work we present results of ground defor-mation measurements inferred through repeat-pass Syn-thetic Aperture Radar (SAR) Interferometry (InSAR) in C- and X-band over Alpine and Apennine sites affected by slope instability. The activity was carried out in the framework of the MORFEO (MOnitoraggio e Rischio da Frana mediante dati EO) project, founded by the Italian Spatial Agency (ASI) and dedicated to landslide risk assessment. A number of areas affected by hydro-geological instabilities have been selected and studied in detail by processing both C- and X-band SAR data through multi-temporal Differential SAR Interferome-try algorithms. InSAR-derived displacements provided on areas of hy-drogeological interest are going to be validated in the framework of MORFEO project by the geological part-nership thanks to the availability of ground truths. In the present work, we present the results obtained by proc-essing through SPINUA, a PS-like algorithm, three ar-eas affected by landslide phenomena: the area around Garzeno and Catasco in the Lombard Alps, the area aver St. Moritz in the Swiss Alps and the Ivancich landslide close to Assisi town in the Italian Apennine. We provide comparison between the deformation maps derived from ENVISAT and those obtained by process-ing a limited number of COSMO-SkyMED images. Our results are also validated by using ERS and RADAR-SAT PS maps freely available on the GeoIFFI web-catalogue (Garzeno), geotechnical investigation avail-able in literature (St. Moritz) and results from SBAS technique (Assisi).
