The Rasuwa disaster of 26 August 2026 in Nepal killed 1,403 people and left over 6,000 missing after a massive landslide and glacial collapse sent a 20-metre-high surge down the Bhotekoshi River at speeds up to 170 kilometres per hour. The catastrophe knocked approximately 10% of Nepal’s installed electrical capacity offline, forcing an immediate halt to power exports to Bangladesh and reducing supply to India.
Damaged infrastructure along the Himalayan corridor severed critical trade routes between Nepal and China. Hydrological planning models no longer hold. The destruction hit over a dozen hydroelectric installations, exposing severe vulnerabilities in surface-level plant designs compared to underground facilities. Cross-border monitoring remains severely constrained, as the Kathmandu-based International Centre for Integrated Mountain Development actively tracks only a tiny fraction of Nepal's 3,000 glaciers. International Loss and Damage climate funding promised at COP27 remains largely dormant, leaving exposed regional economies reliant on external debt.
