Multi-temporal evaluation of landslide-induced movements and damage assessment in San Fratello (Italy) by means of C- and X-band PSI data

This work provides a valuable multi-temporal and spatial investigation of landslide effects in San Fratello area (Messina province, Sicily Region, Italy), by means of C-/X-band PSI (Persistent Scatterer Interferometry) data, integrated with in-situ field checks and crack pattern survey. In February 2010 a catastrophic landslide caused casualties and large economic damages. Thus, an accurate mapping and monitoring of ground motions and impacts turn out to be significantly effective. PSI ground motion rates were cross-compared with local failures and displacement features of single buildings observed in-situ. Landslide-induced motions were detected at local scale over almost 20 years, with a validation of radar data and manufactures crack patterns, to finally achieve a complete and reliable assessment.
