Triggering of Rain-Induced Landslides, with Applications in Southern Italy

Landslides cause fatalities, widespread damages and economic losses. Quite frequently, they are triggered by rainfall. Many studies have investigated the relationships between rainfall characteristics landslide events. This paper reviews two main approaches, physical hydrological, for modelling such relationships. In approach, influence of on slope stability is commonly analysed in terms groundwater infiltration, pore pressure changes balance shear stresses resistances, therefore a considerable amount hydrogeological, morphological geotechnical data required. hydrological statistical-probabilistic study series dates occurrence movements instead carried out. Both types methods briefly presented, with examples from real applications to cases Southern Italy. particular, recent reactivations large rockslide Northern Calabria been modelled means approaches. addition, shallow landslides Calabria, Campania Sicily employing Strengths weaknesses adopted discussed, together causes that may hindered better results considered cases. For illustrated through application cases, research perspectives as well their possible use early warning systems.
