MOMPA: InSAR monitoring in the Eastern Pyrenees

This paper describes the main outcomes of the European research project MOMPA (Monitoring of Ground Movements and Action Protocol). Its objective is to provide useful tools for the prevention and management of risks due to slope movements, based on the satellite monitoring InSAR (Interferometric SAR) technique. The project includes two parts: risk evaluation and the integration of InSAR in an action protocol for Civil Protections. The study area encompasses 4000 km2 including a part of the eastern Pyrenees. The project exploited medium-resolution (Sentinel-1) and high-resolution (COSMO-SkyMed) satellite images to generate ground displacement maps at interregional scale and detect the Active Deformation Areas (ADA). The ADA map was used to select movements with potential risk which were further examined by a local analysis using photo interpretation and fieldwork.
