A massive glacier collapse devastated the Alpine village of Blatten in Switzerland’s Lötschental valley, covering nearly the entire community in mud and debris. About 300 residents had been evacuated just days earlier amid fears the Birch Glacier might give way.
On May 28, a large section of the glacier broke off, sending mud and dust across the area and burying much of the Lonza River bed. Authorities called it a “major catastrophe,” with roughly 90% of the village damaged. One man, 64, remains missing, and search efforts are ongoing.
Swiss glaciologists have long warned that climate change is accelerating glacier melt. In 2023 alone, Switzerland lost 4% of its total glacier volume — the second-largest decline on record. Experts say the collapse was caused by the thawing of permafrost, which weakened the rock beneath the glacier, a stark consequence of rising global temperatures.
Mayor Matthias Bellwald expressed resilience amid the disaster: “We have lost our village, but not our heart… After a long night, it will be morning again.”
This tragedy highlights the urgent need to address climate change, as the melting of glaciers and thawing permafrost continue to threaten Alpine communities and ecosystems.
