Overview
- A glacier–rock collapse on August 26 unleashed a high‑speed sturzflut that swept down the Bhotekoshi/Trishuli valleys and has left well over 1,200 people dead in Nepal with roughly 4,000–4,600 still missing.
- Seismic records and glaciologists say the immediate trigger was a large ice and rock avalanche from the Langtang Lirung area that produced a fast-moving mix of water, ice, mud and debris.
- Reporting from the Tibetan side is tightly controlled and Chinese authorities list far lower casualties, creating major uncertainty about the scope of damage and the number of missing there.
- Rescue teams are concentrating on buried hydropower tunnels and remote settlements where hundreds of workers are feared trapped, while dozens of power projects, homes, roads and border infrastructure have been destroyed.
- The humanitarian crisis is acute: WHO warns of disease from standing water and decomposing remains, authorities are taking DNA samples and doing temporary burials, international aid is being mobilized and Nepal is pressing wealthy emitters for accountability and compensation.
