Since 2006, a GBInSAR LiSAmobile system has been employed to monitor the Ruinon landslide in Valfurva. The landslide is estimated to have a volume of about 30 million cubic meters and is highly disaggregated and rapidly evolving. In 2020, the landslide experienced a prolonged period of exceptional surface velocities, consistently exceeding 1 meter per day.
GBInSAR LiSAmobile monitoring data collected since 2006 have been analyzed to assess the dynamic behavior of the phenomenon, estimate the thickness of the rapidly moving layer, determine the effects of hydrological forcing on slope displacement, and define alert thresholds. The GBInSAR LiSAmobile radar data are used to activate alarms specified in the civil protection plan.

The results demonstrate the importance of implementing long-term monitoring using GBInSAR LiSAmobile in challenging sites like Ruinon, where fieldwork and instrument installation on the moving mass are difficult or impossible.
