A massive collapse of mud and rock into a Himalayan river has triggered catastrophic flooding, resulting in at least 360 confirmed deaths and leaving more than 1,400 people missing across Nepal and China’s Tibet region. Authorities are currently navigating a massive challenge as they conduct search and rescue operations in rugged, remote terrain.
In Nepal, officials have confirmed 359 fatalities, while at least three people have died in the neighbouring Tibet region. Rescue teams are working through thick mud, with over 5,000 army and police personnel deployed to the hardest-hit districts. Helicopters are being used to transport survivors to hospitals, where medical staff are treating injuries ranging from skin burns to broken ribcages.
The disaster has impacted a significant number of foreign nationals. Nepalese authorities estimate that more than 500 foreigners are among the 910 people missing in Nepal. The list of missing tourists spans over two dozen countries, including 177 from India, 63 from the United States, 34 from Australia, 33 from the United Kingdom, and 25 from Canada. Additionally, Beijing’s foreign ministry reported that nearly 100 Chinese nationals are missing in Nepal, while 558 people, including 260 foreigners, remain unaccounted for in Tibet’s Gyirong county.
Chinese Premier Li Qiang arrived at the mudslide site in Tibet on Thursday to personally oversee emergency rescue and relief efforts. Meanwhile, in Nepal, Prime Minister Balendra Shah traveled by road to the severely affected Nuwakot district to assess the damage. The disaster has devastated infrastructure, with roads, bridges, and power grids destroyed, leaving many communities cut off from aid.
While initial reports suggested a magnitude 4.4 earthquake caused the disaster, the US Geological Survey clarified that the seismic activity was actually caused by the massive collapse of glacial rock and ice. Satellite imagery from Planet Labs indicates the debris-laden surge originated along the Lhende River, roughly 20 kilometres from the Rasuwagadhi border crossing. Disaster authorities have warned that a lake formed by the blockage remains at risk of bursting, posing a further threat to downstream areas.
International support is mobilizing to assist with the crisis. The United Nations Office for the Coordination of Humanitarian Affairs has allocated $2 million from its Global Emergency Fund, while the US Department of State has pledged $500,000 in aid and dispatched a disaster response adviser. India has also provided critical supplies, including food, tents, and medicine, and has evacuated thousands from its own border states to mitigate risks from the rising Gandak River Basin.
Climate experts emphasize that the tragedy underscores the extreme vulnerability of the region to environmental hazards. Sunil Acharya, a specialist in climate and public policy, described the event as a brutal example of the climate crisis on the front line. He noted that while Nepal is taking action, the scale of such disasters exceeds the government’s domestic resources, making international cooperation to curb greenhouse gas emissions essential to preventing future catastrophes.
For those on the ground, the situation remains dire. Healthcare worker Tula Bahadur BK, who is searching for five missing relatives in Rasuwa, described the scene as total devastation, noting that entire riverside settlements have been swept away. Many of those caught in the flood were pilgrims traveling to sacred sites like Mount Kailash and Lake Mansarovar, which are deeply revered by Hindu and Buddhist communities. The report also notes that search and rescue operations are proving to be a “massive challenge” as simply “getting to the affected areas … to try and recover the survivors” is proving to be extremely difficult, because the roads and bridges there have suffered extensive damage, said Minelle Fernandez, reporting from the Nepalese capital, Kathmandu. The report also notes that triggering the flash floods, early reports from Nepalese officials suggested an earthquake in the area may have caused the lower section of a glacier to collapse. The report also notes that however, the US Geological Survey noted that the seismic event, initially recorded as a magnitude 4.4 earthquake, was actually the seismic energy generated by the sudden collapse of glacial rock and ice, followed by a huge debris flow. The report also notes that approximately 20 kilometres (12 miles) northeast of the Rasuwagadhi border crossing between Nepal and China, preliminary satellite imagery analysis by Planet Labs indicated that a landslide of ice and rock triggered a debris-laden surge down the Lhende River. The report also notes that thick mud swathed homes, trees, and vehicles, while aerial footage showed collapsed houses, submerged cars, and a metallic bridge washed away by the torrents, in the affected valleys. The report also notes that adding that Canadian officials were monitoring the situation closely, canadian Prime Minister Mark Carney described the flooding as “devastating”. The report also notes that australian Prime Minister Anthony Albanese noted that gathering clear information from the remote area remained challenging due to limited local infrastructure and resources. The report also notes that “It is not simply an unpredictable natural hazard.
