On August 26, 2026, a catastrophic flash flood triggered by a suspected glacial collapse or ice-rock avalanche struck Rasuwa District in Nepal near the Tibet border, causing widespread devastation along the Bhote Koshi and Trishuli river systems.
Casualties and Missing Persons
The death toll is confirmed to be at least 392 people, with estimates rising to over 500 across Nepal and Tibet.
More than 1,000 people remain missing, including hundreds of foreign tourists and pilgrims; nearly 90 Americans and dozens of British citizens are among the unaccounted.
Significant casualties were reported in Rasuwa, Nuwakot, Dhading, Gorkha, and Chitwan districts.
Impact and Damage
Floodwaters surged rapidly, reaching heights of up to 9 meters (30 feet) in 30 minutes, sweeping away villages, bridges, and critical infrastructure.
The Rasuwagadhi border crossing was completely destroyed, and several hydropower projects, including the Rasuwagadhi and Chilime plants, sustained severe damage.
Rescue operations have been complicated by the scale of destruction and the formation of new barrier lakes, which pose a risk of further flooding.
Current Status
Rescue efforts are ongoing but have faced challenges, with some helicopter operations halted due to safety concerns regarding newly formed lakes.
International aid is being coordinated, with countries like the UK, US, and India deploying resources to assist with search and rescue and relief operations.
