Persistent Scatterer Interferometry (PSI) Technique for Landslide Characterization and Monitoring

摘要: : The measurement of landslide superficial displacement often represents the most effective method for defining its behavior, allowing one to observe relationship with triggering factors and assess effectiveness mitigation measures. Persistent Scatterer Interferometry (PSI) a powerful tool measure displacement, as it offers synoptic view that can be repeated at different time intervals various scales. In many cases, PSI data are integrated in situ monitoring instrumentation, since joint use satellite ground-based facilitates geological interpretation allows better understanding geometry kinematics. this work, interferometry conventional techniques have been used characterize monitor Santo Stefano d’Aveto located Northern Apennines, Italy. This defined an earth rotational slide. analysis has contributed more in-depth investigation phenomenon. particular, measurements allowed redefining boundaries state activity, while series permitted deformation pattern relation causes itself. integration provided sound results characterization. punctual information deriving from inclinometers help actual location sliding surface involved volumes, measuring pore water pressure conditions or table level suggest correlation between patterns factors.
