On August 26, 2026, a glacial collapse in the Himalayas triggered catastrophic flash floods along the Bhotekoshi and Trishuli rivers in Nepal, causing widespread destruction in Rasuwa, Nuwakot, Dhading, and downstream districts. The disaster killed over 1,100 people in Nepal and left nearly 4,000 missing, with hundreds of hydropower workers trapped in tunnels. It damaged 12 hydropower projects, knocking out about 10% of Nepal's power capacity, and destroyed roads, bridges, and buildings. Nepal's Prime Minister Balen Shah called it a climate change warning and demanded international compensation from major emitters including India, China, and the US. Nepal formally approached the Fund for Responding to Loss and Damage. International aid and rescue teams from India, China, South Korea, Singapore, and others assisted. The disaster highlighted the vulnerability of Himalayan infrastructure to climate-driven glacial floods.
