Abstract

An integrated approach for the quantitative analysis of earthquake-induced landslide hazard is presented. The method encompasses most of the features for a comprehensive analysis of the phenomenon, such as: first-time slides and reactivations of existing landslide bodies; failures in rock and soil slopes; any kind of geometry of the failure surface; applicable to any scale, from basins to slopes; performance-oriented analysis; deterministic and probabilistic results; seismic hazard scenarios that encompasses both deterministic and probabilistic approaches; analytical computation of co-seismic displacements, through the integration of real accelerograms; results modulated in terms of given return periods and hydraulic boundary conditions. The methodology has been applied to selected sites in Central Italy where different geologic conditions exist, with different types of slope movements and where different seismic sources are responsible for different hazard scenarios and whose results are here shown through a mapping representation integrating all the conditions listed above.
