Multi-hazards in mountain regions: From monitoring to triggering threshold definition

Many natural hazards can interact with each other and lead to or exacerbate the effects of additional catastrophic events, such as landslides following earthquakes, floods following snow-avalanches or landslides and floods induced simultaneously by heavy rainfall. According to the 2019 IPCC special report, the frequency and magnitude of mountain hazards, i.e. snow avalanches, floods due to glacier lake outburst (GLOF), flash-floods, rockfalls and landslides, are projected to increase in a scale never seen, potentially impacting new locations and/or occurring in different seasons than previously. In combination with growth in the population and economy, this changing landscape of mountain hazards will dramatically increase the risk to local populations, leading to growing economic damages in mountainous regions.

This session aims to serve as a transdisciplinary forum, allowing discussion and debate on the future development of the field. In particular, we would like to discuss a series of topics and case studies including, but not limited to:

- Innovative monitoring methods (e.g. DAS, ERT, InSAR, LIDAR, UAV) applied to extreme mountainous environments and helping to better characterize triggering mechanisms;

- The definition of triggering thresholds in monitoring data;

- Developments in numerical processing of large datasets (e.g. machine learning, AI);

- How to link evidence of catastrophic events in natural archives (e.g. tree rings, sediment cores) to the present-day processes.

We are also looking forward to discussing lessons learned from unsuccessful monitoring attempts and/or research.
