Integrated Approaches for Field Mapping by Traditional Investigation and Satellite PSInSAR Data: Results from the Montemartano Landslide (Central Italy)

The study presents an integrated investigation of a complex landslide based on multitemporal stereo aerial photographic interpretations, existing geotechnical monitoring data, and different PSInSAR datasets. available information allowed for the quantification deformation history, also in periods with no field, making it possible to revise geometry compared official mapping. Data from sparse inclinometers are more spatially continuous satellite measurements, showing that two techniques consistent terms cumulative trend response prolonged drought wet periods. Therefore, reliable mass displacements can be monitored using products when ground instrumentations longer operating. Understanding behavior rainfall conditions offers important insight into velocities expected during similar stages enhanced activity. findings helpful support urban planners re-evaluating hazard risk classification implementing efficient mitigation reduce damage.
