Slow-moving landslides yearly induce huge economic loss worldwide in terms of damage to structures/infrastructures and interruption of human activities as well. Within the landslide risk management framework, the vulnerability analysis is a key step entailing procedures mostly based on the identification of the exposed elements, the damage classification and the definition of an intensity criterion. The present paper introduces a two-scale procedure for the analysis of building vulnerability to slow-moving landslides. The intensity parameter (i.e. absolute or differential settlement) derives from the information provided by Differential Interferometric Synthetic Aperture Radar (DInSAR) satellite data, which in the last decade proved to be capable of providing cost-effective long-term displacement archives of structures/infrastructures. The obtained results over two slow-moving landslide-affected areas allowed the generation of empirical fragility curves for masonry buildings that, once further validated, can be valuably used for damage analysis and forecasting.
