Statistical Analysis of Landslide Susceptibility, Macerata Province (Central Italy)

Every year, institutions spend a large amount of resources to solve emergencies generated by hydrogeological instability. The identification areas potentially subject risks could allow for more effective prevention. Therefore, the main aim this research was assess susceptibility territories where no instability phenomena have ever been detected. In order obtain type result, statistical assessments problem cannot be ignored. case, it chosen analyse landslide using flexible method that is attracting great interest in international scientific community, namely Weight Evidence (WoE). This model-building procedure, calculating susceptibility, used Geographic Information Systems (GIS) software means mathematical operations between rasters and took into account parameters such as geology, acclivity, land use, average annual precipitation extreme events. Thus, innovative links with triggering factors precipitation. resulting map showed low weight identifying most susceptible landslides, although all included contributed accurate estimate, which necessary preserve human life, buildings, heritage any productive activity.
