Automatic Ground Deformation Detection from European Ground Motion Service Products

This work addresses the automatic extraction of active deformation areas (ADAs) using a pan European ground deformation dataset, provided by the European Ground Motion Service. The ADA extraction routine is based on the ADA Finder tool, which selects the persistent scatterers that are likely to belong to a surface affected by a ground deformation phenomenon. The result consists of two European ADA maps, associated with the Sentinel-1 ascending and descending trajectories. A preliminary validation of the European ADA maps is addressed by analysing the detected ADAs in the territory of Valle d'Aosta region (Italy), that is affected by the presence of landslides and deep-seated gravitational slope deformations, showing a limited number of false positives.
