“We needed to know how far and how fast the event could travel”

Switzerland’s ETH Zurich professor Jordan Aaron has developed an AI-powered computer model that can simulate landslide scenarios 200 times faster than previous models. The model was used to assess the landslide risk for the village of Brienz/Brinzauls in Graubünden, leading to its second evacuation in November 2024. The technology combines GPU computing with AI algorithms to rapidly simulate thousands of potential landslide scenarios.
