Nepal-Tibet flash flood kills 22, leaves 384 missing after ice-rock avalanche
A sudden flood triggered by an ice and rock avalanche swept through Nepal's Bhotekoshi River valley on Wednesday, killing at least 22 people and leaving 384 others unaccounted for, including 291 foreign tourists. The deluge destroyed villages, roads, and hydropower facilities, prompting officials to urge residents to stay away from riverbanks. Nepal has requested rescue assistance from both India and China, while Chinese state media reported major casualties at the Gyirong Port on the Tibetan border.
The flood struck the Bhotekoshi River around 9 a.m. local time, with the Lhende Khola tributary experiencing the most severe surge. This marks the second flooding of that waterway in fourteen months, following a similar glacial lake overflow in neighboring Tibet last August that killed nine people and damaged a cross-border bridge.
The Kathmandu-based International Centre for Integrated Mountain Development identified an ice-rock avalanche from a Nepali glacier as the trigger, which blocked the river before releasing a sudden downstream surge. Researchers note Himalayan glaciers are melting at double the rate seen since 2000, with extreme weather events becoming more frequent across the region.
This disaster could strain Nepal's disaster response capacity while highlighting the growing vulnerability of Himalayan communities to climate-driven glacial events. The high number of missing foreign tourists may affect regional tourism confidence and prompt international scrutiny of safety protocols. The request for aid from both India and China suggests cross-border coordination may become increasingly necessary as warming temperatures make such catastrophic flooding more frequent in the region.
