Mapping potential release areas and modelling runout distances of permafrost rock slope failures at regional scale for hazard assessment
Résumé
High mountains environments are highly affected by climate change through glacier retreat and permafrost degradation. These phenomena may cause rock slope failures, sometimes provoking far-reaching cascading processes threatening human lives and infrastructure. Increasing knowledge on the triggering mechanism and propagation is therefore required to propose adaptation strategies. In the French Alps, permafrost mapping and extensive rockfall inventories provide relevant data for statistical analysis of their triggering conditions and mobility. In accordance with the GAPHAZ guidelines for hazard assessment (GAPHAZ, 2017), the aims of this study are: (i) to propose a mapping approach of susceptible release areas of rock slope failures and resulting runout distances at a regional scale (French Alps), and (ii) to identify hotspots for further hazard assessment.
