We investigate the possibility of detecting landslide precursors by means of Synthetic Aperture Radar Differential Interferometry. We show a methodology to retrieve signal associated with key precursors of destabilisation for landslides that present characteristics unfavourable to unwrapping and to time series inversion methods. This methodology entails analysis and description of the interferometric phase signal obtained from raw, wrapped interferograms in combination with the analysis of interferometric coherence drops as marker for key geomorphological features of gravitational origin.

Abstract
We investigate the possibility of detecting landslide precursors by means of Synthetic Aperture Radar Differential Interferometry. We show a methodology to retrieve signal associated with key precursors of destabilisation for landslides that present characteristics unfavourable to unwrapping and to time series inversion methods. This methodology entails analysis and description of the interferometric phase signal obtained from raw, wrapped interferograms in combination with the analysis of interferometric coherence drops as marker for key geomorphological features of gravitational origin.
