Swiss avalanche disaster: State omissions blamed by lawsuit plaintiff whose treasures were buried

A year after a devastating avalanche buried 90% of the Swiss village of Blatten, a lawsuit alleges that "culpable omissions" by the state of Valais contributed to the disaster. The massive slide of ice, mud, and debris on May 28, 2025, engulfed the Lötschental village, destroying 130 homes and its church. The debris formed a 2 km long, up to 200m wide, and equally thick cone.

Philosopher and theologian Jean-Marc Tétaz lost his rented chalet in the hamlet of Ried, which housed his scientific library of approximately 5,000 books and a Pechstein painting. He also lost his grandfather's 700-page handwritten memoirs, written to him and detailing his escape from Nazi Germany. The catastrophe also destroyed 18 months of Tétaz's research on Paul Ricœur and the proof of God's existence, work for which he earned income as an independent.

One person died in the disaster. The article, published by Le Temps, indicates that the full details of the lawsuit and the extent of the state's alleged culpability are reserved for subscribers, suggesting a deeper legal and political dimension to the tragedy.
