Overview
- A sudden ice-and-rock collapse on the Langtang border with Tibet generated a fast-moving flood wave that tore down the Bhotekoshi/Trishuli river system and destroyed villages and infrastructure.
- Authorities report roughly 579–600 confirmed dead and between about 1,900 and 2,500 people still missing across Nepal, Tibet and downstream areas, with counts shifting as searches continue.
- Nepal’s army and local teams have flown thousands to safety, using multiple helicopters to move survivors to an army camp at Battar Bazar while ground crews struggle with meters of mud and broken bridges.
- Rescue work was paused after Chinese and Nepali officials warned a newly formed lake on the Tibetan side might overflow, a risk that has complicated cross-border coordination and slowed access to hit areas.
- Scientific agencies linked the catastrophe to a glacier collapse or ice-and-rock avalanche that produced seismic signals, and governments have pledged aid while Nepal has limited foreign search-and-rescue deployments.
