Overview
- A collapse of glacial ice and rock on August 26th off Langtang Lirung sent a wall of water, mud and debris down valleys that destroyed villages, roads and multiple hydropower sites.
- Nepalese authorities place confirmed deaths at roughly 1,200–1,300 and report more than 5,000 people missing across Nepal and Tibet, with counts rising as teams recover bodies.
- Rescuers on September 4th extracted two workers alive from the Trishuli 3A tunnel; both were flown to Kathmandu for treatment and their recovery is the biggest on-the-ground breakthrough so far.
- Hundreds of hydropower workers remain unaccounted for with local officials citing up to about 900 missing and as many as 500 possibly trapped in tunnel systems that rescuers are reaching by drilling, clearing debris and using specialist tunnelling methods.
- Preliminary direct damage is estimated at roughly USD 2.56 billion with about 20,000 houses affected; international aid and health teams have been mobilized and Nepal is planning upgrades to early-warning and monitoring systems to reduce future risk.
