Summary

On August 26, 2026, a massive glacier and rock collapse in Nepal's Rasuwa district triggered a catastrophic flood in the Trishuli River, killing over 1,400 people with thousands more missing and tens of thousands requiring humanitarian aid. The collapse, a roughly two-square-kilometre mass of glacial ice and bedrock, was preceded by months of detectable satellite movement but no actionable early warning system. The disaster devastated communities along Nepal and Tibet's border, destroying homes, infrastructure, bridges, and hydropower projects. World Weather Attribution linked the event to human-caused climate change thawing Himalayan permafrost and destabilizing slopes. Separately, heavy rains in late September caused additional floods and landslides across Nepal, killing at least 21-35 people with several missing and affecting hundreds of families. The August floods left women and girls particularly vulnerable, with displaced persons struggling to find safe housing and facing concerns about harassment and exploitation in temporary shelters. Nepal's Prime Minister called for improved early warning systems and international climate resilience support.
