A method for assessing and managing landslide residual hazard in urban areas

摘要: On February 14, 2010, a large landslide affected the urban centre of San Fratello town (Sicily Island, Southern Italy), causing severe damage to buildings, roadways, and infrastructure, as well about 2000 evacuees. This complex landslide, covering more than 1 km2 in extension, represents one major phenomena that ever occurred Sicily. In order manage risk, civil protection system was activated part initial response emergency (the “emergency phase”). involved Civil Protection Departments both at national (DPC) regional (DRPC) levels, scientific institutions (namely “Competence centres”, CdCs), local administration personnel, technicians. March 8, during post-event recovery phase, ground-based synthetic aperture radar (GB-InSAR) installed monitor ground surface deformation, assess residual analyse its displacement trend. Accurate field surveys building inspections were also performed for validation GB-InSAR data, map plan evacuation-demolishment, check efficiency mitigation works. paper describes outcomes 57 month monitoring campaign (March 2010–December 2014), reporting use data near real-time monitoring, mapping, post-emergency/recovery management activities. The final aim provide personnel with reliable, rapid, easy communication results, designed an enhance understanding phenomena, support decision-making process.
