Abstract: The study focuses on the South Tyrol region, investigating factors influencing debris flow triggering and empirically calculating rainfall thresholds for event occurrence. Through a comprehensive analysis of debris flow events since 1960, cataloging geological and rainfall data, the study is preliminary but innovative step towards a better understanding and therefore mitigation of the risks associated with these phenomena. The main result of this work consists indeed of specific thresholds curves that establish which intensities and durations of rainfall events may cause the triggering of a debris flow.
