The paper develops an innovative methodology for creating a comprehensive multirisk database spanning more than four centuries, which is exceptionally rare in natural hazard studies. Its temporal depth and detailed documentation of impacts provide valuable insights into the long-term dynamics of hazards and their interactions with society. By covering multiple hazard types and cascading events, the study offers broadly transferable methods and findings that will be of interest well beyond the case study area.

This paper proposes a methodology to develop a long-range multirisk database. Combining scattered pre-existing records and intensive research in historical archives provides a 1600–2020 record of past events in a valley of the French Alps. It goes far beyond any inventory existing in terms of number of events, temporal coverage and detailed description of events characteristics in a mountain context. Spatio-temporal patterns are analysed, opening perspective for multirisk assessment.
