Survivors describe Nepal‑China flood disaster as rescue teams search for missing

A sudden glacier collapse on the Nepal‑China border on Friday set off a massive landslide and flash‑flood that raced down the Trishuli valley. The torrent, described by locals as a "tsunami‑like" surge of water and debris, has claimed over 550 lives and left more than 1,400 people unaccounted for, many of them foreign tourists.

Why the disaster matters

The event hits a region already reliant on tourism and hydropower. With dozens of pilgrims and workers caught in the flow, the loss of life underscores the vulnerability of mountain infrastructure to climate‑driven glacial melt. The damage to dam sites and residential camps also threatens Nepal’s energy projects and could strain cross‑border relations with China as both sides assess the cause and response.

First‑hand accounts from the valley

Sivaranjani Muthunathan, 46, was travelling by bus with 56 other pilgrims from India’s Tamil Nadu when the convoy stalled in what looked like a traffic jam. "Then there was fog, smoke, something that seemed to suddenly engulf us," she told reporters, showing a video of the rushing water. Vehicles were swept away or buried under mud.

"One by one, we also climbed out through the driver's side," she said, recalling how she scrambled up a hill after the bus was engulfed.

Another pilgrim, Vijayabhuvaneshwari, 53, described the scene: "We had no choice. Every vehicle in front of us, behind us, was gone." She added that the sound of rocks crashing sounded like explosions as the valley filled with boulders.

Older members of the group received help from Poonguzhali Ponmambadan, 61, who untied her sari to fashion a rope for her husband, allowing him to lift several elderly passengers.

Workers at a hydropower site in the Trishuli valley also recounted the speed of the disaster. Dev Shrestha, rescued by helicopter, said there were at least 400 workers on site and "more people died than were rescued". Buddha Tamang survived because he was inside a tunnel when the flood struck, emerging after more than 24 hours to be airlifted out.

Engineer Ananay Sharma, 29, from India, recalled hearing a loud noise and seeing water rise to six metres. "When I came out, everything was gone, only the river remained," he said, noting that a residential camp had been completely washed away.

In the Shanti Bazar area near the epicentre, Gorakh Khatka described having only twenty seconds to react before mud and water surged to twenty feet. "We ran for our lives and spent more than 48 hours on a hill before help finally arrived," he said.

Rescue operations and damage assessment

Helicopter crews have been flying continuously, plucking survivors from isolated valleys and transporting them to medical facilities. The Nepalese army and disaster response teams are coordinating with Chinese authorities to locate missing tourists and assess the stability of the glacier that triggered the landslide.

Authorities have warned that further avalanches could occur as the destabilised slope continues to melt. Ongoing searches are expected to last weeks, and officials say they will review construction practices at high‑altitude dam sites to prevent similar tragedies.

The disaster is likely to prompt a review of climate‑risk assessments for infrastructure in the Himalayas, and may lead to tighter cross‑border cooperation on early‑warning systems.
