Overview
- A glacier collapsed on Wednesday, sending a high-speed torrent of ice, rock and mud roughly 22 kilometres downvalley to the Gyirong border in about six minutes, according to Chinese reconstruction of the event.
- Official tallies have climbed into the mid- to high-700s dead across Nepal and Tibet and roughly 3,000 people remain unaccounted for, with totals still changing as teams recover bodies and update lists.
- Rescue crews say thick mud, repeated landslides, bad weather and blocked roads have made searches slow and dangerous, forcing some teams to withdraw and reducing the chance of finding survivors in buried tunnels and sites.
- Beijing has flown supplies, tunnel-rescue specialists and drones to help operations, and Kathmandu has reversed an earlier restriction to permit foreign search-and-rescue and forensic teams while it seeks billions in reconstruction aid.
- Scientists and officials warn the disaster reflects growing glacier instability from long-term warming, a risk that threatens Himalayan communities and hydroelectric workers and raises urgent needs for DNA identification and public-health support.
