On May 28, 2025, a catastrophic glacier collapse occurred in Blatten, Switzerland, triggering a massive mudslide that devastated the village. The event followed growing concerns about the stability of the Birch Glacier, exacerbated by accelerated melting due to climate change.
Drone footage captured the moment a large section of the glacier broke away, sending a torrent of ice, mud, and rock into the valley. The village had been evacuated on May 19 as a precaution. One resident remains missing. Initial reports indicate that 90% of the village has been either covered or destroyed.
The Swiss government has pledged financial support to the displaced residents. Experts warn that further collapses could occur, as melting glaciers and thawing permafrost destabilize the Alps. The Swiss Glacier Monitoring Network (GLAMOS) has reported significant glacial ice loss in recent years, emphasizing the urgent need for emissions reductions.
