Two workers were rescued alive from a tunnel at the Upper Trishuli 3A Hydropower Station in Nepal on Friday, nine days after a glacier collapse triggered a massive ice, rock and mudslide through the Trishuli River valley.

The two workers, Sanjay Sah and Kabir Maharjan, were found inside the tunnel and taken for medical treatment. Rescue teams continue searching for other people believed to be trapped in tunnels at several hydropower projects.

The initial debris arrival on the floodwaters.

Event: 26 August 2026, 08:37 NPT. Ice-and-rock collapse from Langtang Lirung’s north flank, registered worldwide as a magnitude 5.2 seismic event; USGS determined no earthquake occurred. Debris flood reached Gyirong Port (Tibet) within ten minutes, then Rasuwa, Nuwakot and Dhading districts in Nepal along the Lhende Khola, Bhotekoshi and Trishuli, about 100 km in total. Copernicus EMS activated (EMSR927) the same afternoon.

Counts, all as of their stated dates and expected to change: NDRRMA via UN OCHA Flash Update 5 (1 Sep, 13:00 NPT) — 1,003 dead, 3,916 missing, 41 bridges destroyed, emergency declared in 15 municipalities, some 65,000 people affected. Tibet side (Chinese authorities, evening of 29 Aug) — 16 confirmed dead, 546 missing. Twelve hydropower facilities affected; joint Nepal, India and China rescue operations at four.

Hazard is ongoing: the source area remains unstable and monitoring bodies (USGS Landslide Hazards, GFZ, ICIMOD, HIRISK) all mark their assessments preliminary. No official inquiry exists yet. Claims that Chinese dams in Tibet caused the flood are not supported by any body that has located the source.
For the sourced timeline with every figure dated, I compiled a longer documentary from the official releases.
