Mapping potential release areas and modelling runout distances of permafrost rock slope failures at regional scale for hazard assessment
International audience 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 know...
