VIDEO: Glacial Lake BURSTS — Thousands Missing

A wall of mud and floodwater tore through the Nepal-Tibet border on Wednesday, killing dozens and leaving nearly 1,500 people missing on both sides of the frontier.

Quick Take

A flash flood and mudslide hit Nepal’s Rasuwa district and Tibet’s Gyirong County on the same morning, August 26.
Nepal reported at least 95 to 98 deaths, with hundreds still missing, including foreign tourists.
Chinese state media reported three dead and 265 missing after a mudslide struck the Gyirong border crossing.
Officials suspect a glacial lake outburst flood in Tibet triggered the disaster before it swept downstream into Nepal.

A Border Region Torn Apart In Minutes

The disaster struck early Wednesday morning along the Bhote Koshi River, which flows from Tibet into Nepal’s Rasuwa district. Villages, roads, bridges, and power projects vanished within minutes as the surge moved downstream.

Nepali officials say the death toll climbed past 95 through the day, with several hundred more people unaccounted for, many of them foreign tourists caught along the border corridor.

Rescue teams in Nepal faced brutal conditions from the start. Roads and bridges connecting the affected districts to the outside world were destroyed, cutting off Rasuwa, Nuwakot, Dhading, Chitwan, and Gorkha.

Nepal’s disaster management authority told residents near riverbanks in those districts to stay alert and move to higher ground immediately, warning that more water could still be coming down from the mountains.

Tibet’s Gyirong County Counts Its Own Losses

On the Chinese side, the mudslide slammed into the Gyirong border port around 10:30 a.m. local time. Xinhua reported three people killed and 265 missing as of Wednesday evening, calling the numbers preliminary and still under verification.

China’s state broadcaster CCTV described the toll as a “preliminary tally” from local authorities working through a chaotic scene.

The mudslide is believed to have originated on the Nepali side of the border before crossing into Gyirong County, according to Xinhua’s reporting.

Search-and-rescue crews, including People’s Liberation Army helicopter units, moved into the area within hours. Beijing pledged roughly 17 million dollars in emergency disaster relief and rescue funding to support the response.

A Familiar Culprit In A Warming Himalaya

Investigators in both countries are examining whether a glacial lake outburst flood set off the disaster. These lakes form when melting glaciers pool behind loose rock and ice, then suddenly break through, sending huge volumes of water and debris crashing downhill.

A similar glacial lake failure struck the same Bhote Koshi River corridor last year, killing at least nine people, a sign this stretch of border has grown increasingly unstable.

The region has a documented history of these fast-moving disasters. Nepal has recorded repeated landslide and flood events tied to intense monsoon rain and glacial melt in recent years, often with early death tolls that rise sharply once rescue crews reach cut-off villages.

For now, families on both sides of the Himalaya are left waiting. Nepali crews are digging through debris in Rasuwa while Chinese rescue teams comb the wreckage at Gyirong.

The combined missing count, drawn from Nepali and Chinese figures, has approached 1,500, underscoring how quickly a single morning of floodwaters can erase roads, bridges, and entire communities in one of the world’s most rugged border regions.
