  1. Approccio analitico per la valutazione della pericolosità da frana: l’esempio di un’area di El Salvador (C.A.)

  2. TASKS - Define causes and typology of landslides - Individuate and map all the landforms indicating instability conditions or that can control slope processes - Define hazard models - Define hazard classes and mapping rules PRODUCTS - Geomorphological and Landslide Hazard Maps (scale 1:25.000) - GIS open database setting-up APPLICATIONS DATABASE AND ACTVITIES - bibliographic data collection and analysis; - vectorized geological map; - geological and geomorphological field control; - aerial view (helicopter); - vectorized aerial photographs analysis; - vectorized topographic maps; - DTEM (Digital Terrain Elevation Model) extraction; - slope analysis; - GIS (Geographic Information System) data spatial analysis; - hazard zoning criteria definition; - hazard mapping. - Civil protection - Land-use planning - Landslide Hazard geotechnical assessment - Landslide Risk Assessment
