Snow Avalanche Slope (2D)
Interactive 2D snow avalanche simulator: tune slope angle, snowpack depth and weak-layer stability, watch shear stress vs. shear strength decide when the weak layer fails, and see the slab flow and entrain mass downslope.
This 2D simulator visualizes a snow avalanche as a weak-layer failure problem: a cross-section of the snowpack sits on a slope whose angle you control, with a buried weak layer whose bonding strength you can weaken or reinforce. The live gauge tracks the shear-stress-to-shear-strength ratio in real time — driven by slope angle and snowpack depth on the stress side, and by weak-layer stability on the strength side — so a slope can release naturally once the ratio passes 1, or hold until a deliberate trigger tips it over. Once released, the slab accelerates downslope, entrains snow to grow heavier and faster, then slows and stops as the terrain flattens into the runout zone.
Tune slope angle, snowpack depth and weak-layer stability to see when shear stress overwhelms shear strength and triggers an avalanche that flows and grows downslope.
