Catastrophic flash floods and mud surges triggered by a glacial collapse hit communities along the Nepal–China border, with heavy damage reported in northern Nepal and parts of Tibet. Nepal’s disaster authorities report rising fatalities and large numbers of people missing, while Chinese state media report deaths and continued searches in the Tibet border region near Gyirong Port.

Rescue operations are ongoing across the affected area, including helicopter deployments and ground searches, and authorities warn that further flooding may occur. Accounts describe the surge arriving quickly and sweeping away homes, roads, vehicles, and infrastructure along river systems including the Bhote Koshi, Lhende Khola, and Trishuli. Nepali officials report that people were urged to relocate from low-lying areas, while Tibet authorities mobilize emergency workers, vehicles, and additional teams to address blocked waterways and damaged access routes.

On the cause, outlets cite the U.S. Geological Survey’s determination that the event is a glacial collapse rather than an earthquake, with climate and hydrology experts pointing to ice/rock avalanches and debris-flow dynamics. Several reports also highlight uncertainty in early assessments and evolving casualty figures, including missing tourists and foreign nationals.
