Abstract
Ground-based Synthetic Aperture Radar (GB-SAR) interferometry is used to monitor the Tessina landslide. This is a complex mass movement in the Italian Eastern Alps. Radar data, acquired during a 10-day campaign, are interferometrically processed. Image couples taken at the same position but at different times are used to estimate terrain slope deformations on a short temporal scale of a few hours. In addition, SAR images acquired with a baseline are processed to extract information on the current topography of the landslide area. Comparison with the terrain morphology of the scene at earlier times allows to evaluate the landslide activity on a long time scale spanning a few years.
