Glacial Collapse Triggers Deadly Flash Floods in Nepal and Tibet

A catastrophic glacial collapse near the Nepal-Tibet border triggered devastating flash floods on August 26, 2026, killing hundreds and leaving more than 1,400 people missing across both countries. The disaster has inflicted massive destruction on infrastructure, cut off remote communities, and prompted warnings of further flood risks from newly formed lakes. The event began when a high-altitude ice and rock avalanche crashed into a valley, sending a torrent of mud, water, and debris surging down the Bhotekoshi and Trishuli river systems. The flow, which scientists say traveled at speeds up to 165 feet per second, obliterated settlements including Timure, Rasuwagadhi, and Trishuli Bazaar.
