A catastrophic glacier collapse in the Himalayas on Wednesday unleashed torrents of ice, rock, mud, and debris, killing more than 600 people across Nepal and China’s Tibet region and leaving an estimated 2,500 missing, according to reports from Reuters and CBS News.
The disaster struck a mountainous border area, leveling entire towns and destroying critical infrastructure, including schools, hospitals, and hydroelectric plants. In Nepal, the disaster-management authority reported 579 deaths on Friday, though Nepali police later listed the death toll at 553. On the Chinese side, state media reported seven deaths. The number of missing persons remains high, with 1,924 unaccounted for in Nepal and 554 missing in China.
Technical Assistance and Infrastructure Collapse
Nepal’s Foreign Minister, Shisir Khanal, stated that while the country can manage general search and rescue operations independently, it requires foreign expertise in specialized technical areas. These include rescuing individuals trapped in tunnels, DNA testing, and the identification and long-term storage of bodies. Khanal noted that hospitals have been overwhelmed by the deceased and lack the necessary refrigerators for storage.
The flooding caused extensive damage to transport networks, destroying approximately two dozen bridges. Nepal has requested bailey bridges from China and India to restore communication and transport services. Additionally, officials expressed concern over people trapped in tunnels at hydroelectric plants, an area where Nepal lacks the necessary equipment and technical knowledge for rescue operations.
Rescue Efforts and Ongoing Risks
Search and rescue operations have been extensive, with more than 3,700 people rescued in Nepal. In the Rasuwa district, the Nepali army has rescued 350 people from a tunnel associated with the Upper Trishuli-1 Hydropower Project, though more than 100 others are believed to remain trapped by thick mud.
On the Chinese side of the border, rescue teams rappelled from wooded slopes into a flattened border-crossing area. Satellite imagery shows the once-busy checkpoint has been reduced to a muddy area of debris. Rescue official Zou Mingqi told state media that the area is now nothing but debris
.
Authorities remain on high alert due to the risk of further flooding. A new lake formed high in the mountains following the initial collapse, located at an elevation of 2,950 meters and approximately 10 kilometers from the Gyirong Port border crossing. Rescue workers were ordered to stop operations temporarily on Friday due to concerns the overflowing lake would release more water. Additionally, Nepali police issued an alert after reports that a dam on the Tibet side had burst.
Survivor Accounts and International Impact
The U.S. State Department estimates that approximately 90 Americans are among the missing. Other nations, including Britain, Japan, South Korea, Sri Lanka, Bangladesh, India, and China, have offered search-and-rescue assistance, which Nepal has declined in favor of technical support.
Survivors described the event as a wall of dark water. Anjana Raja and Pattabiraman Venkatesan, a couple from the San Francisco Bay Area on a pilgrimage to Tibet, were in a tour bus in Nepal’s Rasuwa District when the flood hit. Venkatesan described the water as looking like a tsunami, but dark black
, while Raja recalled hearing the screams of people being swept away. The couple escaped by climbing a treacherous, slippery slope of mud and stones to a flat area on a nearby mountain, where they spent the night in a goat shed before being airlifted to safety.
