A glacier collapse near the Langtang Lirung peak unleashed a flash flood along the Nepal‑Tibet border on August 26, 2026, killing 177 people.
Early media reports blamed an earthquake, but United States Geological Survey data confirm the event was a glacial collapse, registering an impact equivalent to a 5.2‑magnitude quake.
The sudden release of ice, rock and meltwater surged downstream, causing river levels to rise nine metres within half an hour and destroying monitoring stations along the way.
Scientists warn that the Himalayas are melting faster than ever. Loss of glacial ice and thawing permafrost increases the frequency of landslides, avalanches and glacial lake outbursts, threatening surrounding communities.
The tragedy underscores the need for better monitoring and early‑warning systems in the high‑mountain regions of South Asia.
