Short summary
Short summary
We present the first extended intercomparison of snow avalanche flow simulation tools. In this pilot-study, simulation results of mainly thickness/depth-integrated shallow flow models are compared for three simple test cases representative of standard applications. This analysis serves as a first quantitative assessment of the uncertainty introduced by the different implementation workflows (e.g., numerical schemes, ad-hoc treatments, geo-data handling, curvature treatment, etc.).

Short summary
Our study investigates the initiation of snow slab avalanches. Combining experimental data with numerical simulations, we show that on gentle slopes, cracks form and propagate due to compressive fractures within a weak layer. On steeper slopes, crack velocity can increase dramatically after approximately 5 m due to a fracture mode transition from compression to shear. Understanding these dynamics provides a crucial missing piece in the puzzle of dry-snow slab avalanche formation.

Our research reveals the power of high-resolution satellite synthetic-aperture radar (SAR) imagery for slope deformation monitoring. Using ICEYE data over the Brienz/Brinzauls instability, we measured surface velocity and mapped the landslide event with unprecedented precision. This underscores the potential of satellite SAR for timely hazard assessment in remote regions and aiding disaster mitigation efforts effectively.

Short summary
Short summary
This study investigates how forests affect the behaviour of snow avalanches through the evaluation of the amount of snow stopped by the trees and the analysis of energy dissipation mechanisms. Different avalanche features and tree configurations have been examined, leading to the proposal of a unified law for the detrained snow mass. Outcomes from this study can be directly implemented in operational models for avalanche risk assessment and contribute to improved forest management strategy.

Short summary
Advanced 3D numerical models can simulate alpine mass movements at the slope scale, but their use in natural hazard mapping remains challenging. We present a tool that converts 3D simulation results into 2D maps, making them more accessible and useful for hazard assessment and mitigation. Applied to an ice avalanche simulated with the Material Point Method, it reveals key features such as slope-normal velocities and flow detachment from terrain, which are often overlooked in simpler models.
