A New Digital Catalogue of Harmful Landslides and Floods in Italy

Landslides and floods are widespread and recurrent in Italy, where they cause damage and pose a threat to the population. To estimate geo-hydrological risk in Italy, catalogues of landslide and flood events that have caused damage to the population were compiled from a variety of sources. The catalogues covers the 1,943-year period from 68 A.D. to 2010, and list 3,310 landslide events and 2,624 flood events that have resulted in deaths, missing persons, injured people, and homeless. For each event in the catalogue, different types of information were collected and organized in a database. We describe the Spatial Data Infrastructure (SDI) we have implemented to collect, store, analyze, and disseminate the historical information, and results of the analysis of landslide and flood risk to the population.
