Nepal-China Glacier Collapse Leaves Hundreds Dead, Thousands Missing
A glacier in the Himalayas broke apart and sent a huge wave of ice, rocks, mud and water downhill.
The disaster affected areas in Nepal and China near their border.
Hundreds of people were reported dead, and more than 3,000 were still missing.
Some missing workers may be trapped inside tunnels at hydropower plants.
Rescuers had trouble working because of rain, rising rivers and more landslides.
A new pool of water formed behind a landslide, creating fears of more flooding.
Nepal began burying badly damaged bodies after collecting DNA samples to help identify them.
China said the glacier’s instability was connected to the long-term effects of global warming.
Other reports said the exact cause of the collapse was not yet certain.
A glacier collapse sent ice, rock, mud and debris through Himalayan valleys on Wednesday.
Reported death tolls ranged from 750 to 797 in Nepal and China, with more than 3,000 missing.
Floods damaged hydropower projects, and hundreds of workers may be trapped inside tunnels.
Rain, rising rivers and a new landslide-created lake or dam repeatedly disrupted rescue operations.
Nepal began burying unidentified victims and requested international help with rescue and forensic identification.

Cautious assessment
Cause of the collapse
Climate-linked explanation
Chinese state media and officials said glacier instability resulted from the long-term effects of global warming and represented an emerging type of cryosphere disaster.
Cautious assessment
Other reports said the exact cause remained unclear, while citing accounts that a glacier on the southern slope of Lirung Peak fractured and triggered an ice-rock avalanche.
Scale of the disaster
Climate-linked explanation
Officials described the event as the most severe cross-border disaster between Nepal and China in recent years, with rescue operations at an unprecedented level of difficulty.
Cautious assessment
Independent assessment of the disaster’s full scale in Tibet was limited because the region was largely inaccessible to foreign journalists.

- People affected
- The Red Cross estimated that more than 90,000 people in Nepal were affected or potentially affected.
- Hydropower workers
- Nepal listed 933 hydropower workers among the missing; around 350 people were believed possibly trapped in a Trishuli 3A tunnel.
- Mass burials
- Nepal buried more than 100 unidentified bodies and collected DNA samples and identifying details for possible later identification.
- Rescue and aid
- China mobilised more than 2,100 rescuers and allocated at least 220 million yuan, while Nepal requested specialised international rescue and forensic assistance.
- Foreign assistance
- India and China sent specialist teams; the United States, Canada, the United Kingdom, the United Nations, the European Union, Malaysia and other organisations announced assistance.
