Radar Technologies for Landslide Detection, Monitoring, Early Warning and Emergency Management

Landslide detection and monitoring represent a starting point to produce hazard and risk maps useful for proper urban planning and emergency management. In this chapter, different applications of radar interferometric techniques are presented to prove their applicability for detection, mapping and monitoring landslides in different geological settings and with different operative conditions. Data acquisition was carried out through satellite (operating in C-band) and ground-based (operating in Ku-band) sensors. In particular, in this chapter, the application of radar interferometry for landslide detection (Arno River basin), for landslide monitoring (Santo Stefano d’Aveto landslide), for landslide hazard scenario definition (Montebeni landslide) and for landslide emergency management (Santa Trada landslide) are presented and discussed. The different applications highlight the capability and suitability of these techniques to work in different operative settings (i.e.‚ different phenomena and geological framework) and for different aims (survey, early warning and emergency assessment).
