This research aims to assess the impact of landslides on 250 bridges located in the territory of Caserta according to the Italian " Guidelines for risk classification and management, safety assessment and structural health monitoring of existing bridges". Such a procedure provides a structured approach for evaluating bridge susceptibility, vulnerability, and exposure of bridges to landslide hazards. The study enables a rapid and simplified determination of the main landside parameters, focusing on the assessment of landslide activity, magnitude and velocity. The latter is derived from satellite based radar interferometry data provided by the European Ground Motion Service. The results obtained from these parameters are used to define the attention class of each structure. The study highlights the practical application of the guidelines to enhance bridge safety. Furthermore, it provides a comprehensive dataset to identify landslide hazards in the vicinity of bridges and to support effective risk mitigation and safety planning. 1. Introduction Italy is particularly susceptible to landslides due to its complex geological setting, mountainous terrain, and various triggering factors, such as earthquakes and intense rainfall. Historical records indicate a high level of risk: over the III Fabre Conference: Existing Bridges, Viaducts, and Tunnels: Research, Innovation, and Applications Assessing landslide susceptibility for Italian bridges: a case study in the Caserta province Mirza Adeel Zeb a *, Pasquale Bencivenga a , Mattia Zizi a , Gianfranco De Matteis a a Department of Architecture and Industrial Design University of Campania “Luigi Vanvitelli”, Aversa 31081, Italy
