Probabilistic analysis of vulnerability of buildings to slow-moving landslides: a study in two municipalities in southern Itaky.

The paper presents a probabilistic analysis of the vulnerability of buildings interacting with slow-moving landslides. With reference to two municipalities of the Calabria region (southern Italy) severely affected by this type of slope instabilities, the combination of data collected by way of expeditious damage surveys with building settlements retrieved from the use of Differential Interferometry Synthetic Aperture Radar (DInSAR) techniques allows generating separate couples of empirical fragility and vulnerability curves for the two investigated urban areas. The comparison of the obtained results highlights that the use of such tools for damage forecasting purposes in other landslide-affected areas requires selecting - from a statistical point of view - building samples belonging to the same data population (i.e. referring to homogeneous land-urban systems).
