Swiss Valley Faces Rebuilding After Devastating Rockslide Buries Village

A new hazard map has been unveiled for the Lötschental valley, offering insights into future development challenges. The map, prepared by Swiss experts, highlights significant risks from rockfalls and snow avalanches, with vast stretches of land affected. Notably, the red zone, where construction is prohibited, has expanded due to rockfall deposits. Authorities are committed to rebuilding Blatten, a village currently buried under a massive debris cone following a rockslide.

The map serves as a solid foundation for planning future building sites that will remain safe in the long term, not just today. It accurately reflects the current situation and provides a realistic view of what is feasible for development. Geographer and climate researcher Christian Huggel believes Blatten could become a trailblazing example for life in Alpine valleys, demonstrating how to rebuild and adapt to such hazards.

The rockslide that struck Blatten has not only buried the village but also transformed the surrounding landscape, creating new hazards. Authorities aim to commence the rebuilding work in Blatten by 2026, allowing the first residents to temporarily return to still-intact houses.

The newly released hazard map offers valuable insights into the future of the Lötschental valley, guiding development plans that prioritize safety over the next century. Blatten's rebuilding process will serve as a test case for adapting to Alpine hazards, with authorities committed to a 2026 restart.
