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.
