A 500-member WhatsApp group set up by engineers before the Aug. 26 flood is now feeding rescuers tunnel drawings, access routes and worker data as they search six buried hydropower sites for about 900 missing people.
2.2 million tonnes of mud and debris reshaped the Trishuli valley and sealed tunnel entrances, forcing crews to rely on remote guidance because layouts on the ground no longer match normal plant conditions.
At Chilime, no one has been found alive, though industry and power officials say at least eight people may be trapped there and 46 more at Rasuwagadhi, where rescuers advanced 250 meters into one tunnel before hitting a blockage.
At Upper Trishuli 3A, crews took nearly six days to reach a buried entrance and have tried sending oxygen through pipes into possible cavities while excavators clear boulders from tunnel mouths.
The glacier-collapse flood killed more than 1,200 people, left over 4,000 missing and knocked out 10% of Nepal's generating capacity, turning unfinished and operating hydropower tunnels into a central focus of the rescue.
With 900 workers trapped in tunnels, could the looming breach of a newly formed barrier lake trigger a devastating second wave?
CCTV shows the flood struck in under ten minutes; what happened to the dozens of international travelers trapped at the border?
Why are desperate flood survivors forced to sell their emergency food rations just to survive the hidden medical crisis inside relief camps?
Nepal’s 2026 Langtang Glacier Disaster: Over 1,200 Dead, 4,200 Missing, and a $5 Billion Recovery—Rescue, Science, and the Global Climate Justice Crisis
Overview
On August 26, 2026, a catastrophic glacial collapse on Langtang Lirung mountain triggered a massive flash flood and debris flow that surged through Nepal’s Rasuwa and Nuwakot districts. The disaster blocked hydropower tunnels with mud and debris, trapping hundreds of workers and forcing the Nepalese army to launch large-scale rescue operations. The collapse also formed a temporary lake that overflowed, raising fears of renewed flooding, while destroyed bridges left remote communities dependent on helicopters for supplies. The floods knocked out major hydropower capacity, halted electricity exports, and caused billions in damage, exposing gaps in disaster warning systems and highlighting the urgent need for regional cooperation and climate justice.
