A glacial collapse sends deadly floods along the Trishuli through Nepal and Tibet

Flash floods and mudslides along the Trishuli River struck the area between Nepal and Tibet, in China. An early count said at least 160 people were killed in Nepal, with hundreds injured and 463 others missing, including more than 200 tourists. Chinese Communist Party officials reported three deaths and 265 people missing in Tibet. Gyirong County and its port were severely affected.

Nepali officials said bridges, roads, power stations, and entire villages had been swept away. Some areas were still completely cut off from search and rescue. The damage list is infrastructure and settlements, not only a river gauge. The early missing figure of 463 includes the tourists named in that count.

The United States Geological Survey later said a glacial collapse and debris flow, not an earthquake, caused the seismic event near the Nepal-Tibet border and the flooding that followed. That later scientific account put the deaths at least at 392 and the missing at more than 900. The survey's point was the cause: ice and debris, not a tectonic quake.

Nepal's death toll was then reported at 669, with more than 2,400 people missing. A further report on the floods said they had killed more than 1,000 people in Nepal and Tibet together. These are successive counts, not one number repeated. Each figure belongs to the day it was published, and the toll rose as reporting continued.

After the floods, several countries and organizations pledged more than 19.8 million dollars in emergency humanitarian aid. The donors named include Canada, the European Union, the United Kingdom, the United States, and the International Red Cross and Red Crescent Society. The aid figure is a pledge total, not a reconstruction estimate. It sits alongside the casualty counts rather than replacing them.

The confirmed picture is a Trishuli flood disaster caused, according to the geological survey, by a glacial collapse and debris flow. Early local counts differed by side of the border. Later tallies moved through at least 392 dead, then 669 dead in Nepal with more than 2,400 missing, and a report of more than 1,000 dead in Nepal and Tibet, with aid pledges above 19.8 million dollars.
