At least 160 people were killed and hundreds more missing after a glacial collapse triggered a devastating flood along the Nepal-Tibet border on August 26, 2026, with rescue efforts hindered by blocked roads and damaged infrastructure.
The floods, initially misreported as an earthquake, were confirmed by the U.S. Geological Survey (USGS) to have resulted from a glacial collapse and debris flow, leaving entire villages submerged and critical trade routes destroyed. Over 1,300 people remain unaccounted for, with officials warning of heavy casualties or loss of property in the hardest-hit regions.
The Glacial Collapse and Initial Confusion
Scores of Hindu pilgrims missing in Tibet-Nepal floods
The disaster began when a glacier in Nepal’s Rasuwa district collapsed, sending a wall of mud and water surging through valleys and communities. Initial reports, including from Nepal’s Foreign Minister Shishir Khanal, described the event as an earthquake that triggered a landslide, blocking the Bhote Koshi River. However, the USGS later clarified that no seismic activity occurred, with analysis of satellite imagery and seismic data confirming the flood was caused by glacial melt and debris flow (CBS News). This event was initially reported as a magnitude 4.4 earthquake, the USGS stated. Additional analysis of nearby seismic stations, long period seismic waves, and satellite imagery led to the determination that the seismic event was instead a glacial collapse and debris flow, and that no earthquake had occurred. The confusion delayed emergency responses, as rescue teams faced inaccessible terrain and disrupted communications.
Human Toll and Missing Pilgrims
At least 160 bodies were recovered in Nepal, while Chinese state media reported major casualties in Tibet, including three deaths. Over 1,300 people remain missing, with hundreds of foreign tourists among the unaccounted, including 33 Americans, 34 Australians, and 24 Canadians (CBS News). The Isha Foundation, linked to Hindu spiritual leader Sadhguru, reported that 77 pilgrims were present at the Nepal-China border immigration office when the flood struck, with many now missing (The Straits Times). Sadhguru, whose real name is Jagdish Vasudev, posted an emotional video message from Tibet on his social media accounts, with several million followers. Some 77 pilgrims were at the Nepal-China border immigration office when the flood hit on Aug 26, he said in a post alongside a terrifying clip of a surveillance video from the Chinese side of the frontier, when a wall of mud and debris crashed over the border building. The pilgrims were part of several Hindu groups organised by Isha Foundation of Sadhguru, who had been visiting the snow-capped Mount Kailash in Tibet, sacred also to Tibetan Buddhists. Literally, the entire group was there in the building, this is a terrible and extraordinary event,
he said, as anguished wails from other pilgrims with him are heard over the video. All phones are off, telecommunications are down, roads are blocked, we are unable to go there,
he said, tears in his eyes. The tsunami-like rumble of water and mud was caused by a glacial collapse that sent a flow of debris engulfing the valley. We have no any official information… but looking at the scale of destruction, it looks bad,
Sadhguru said. The same building where we were for the immigration just a week ago, that entire building is washed away, and part of the town is washed away.
Catastrophic floods kill over 350 in Nepal and Tibet
Entire villages have disappeared, said David Fisher, head of the International Red Cross in Nepal, adding that a critical artery for commerce between China and Nepal has also now been damaged. The pilgrimage to Kailash and Lake Mansarovar is organised annually by India’s foreign ministry with Chinese authorities. It restarted in 2025 for Indians for the first time since the 2020 clash.
Government and International Responses
Nepal’s President Ramachandra Paudel called the disaster extremely saddened
by the loss of lives and property caused by the sudden flood,
urging intensified rescue efforts, while district administrators warned of potential further casualties (CBS News). The Nepal Electricity Authority confirmed damage to six hydropower facilities, exacerbating the crisis in remote areas (CBS News). Dozens of U.S. nationals were among the 341 foreigners listed as missing, according to Nepal’s Tourism Board, citing information from tour companies. Hikmat Singh Ayer, CEO and senior director of Nepal’s Tourism Board, told CBS News that 403 people were unaccounted for after the flooding. He said that among the missing foreign nationals are 33 Americans, 34 Australians, 24 Canadians, 4 Germans, 19 Malaysians and one Israeli. Chinese state broadcaster CCTV later reported that at least 558 people were believed to be missing on the Tibet side of the Nepal-Tibet border, according to The Associated Press. It said 260 of the 558 were foreigners. The Nepal Electricity Authority (NEA) confirmed that six of its major hydropower and transmission facilities were damaged in the flooding. We do not exactly know the extent of damage, but the flood is big, and it could have damaged many settlements,
Nepal Police spokesman Abi Narayan Kafle told the French news agency AFP. We have alerted people who are staying near the riverside to relocate … and deployed all our resources.
In a social media post, U.S. Secretary of State Marco Rubio expressed U.S. solidarity with the Nepali people, saying his department stands ready to support the government of Nepal with needed humanitarian assistance.
China’s President Xi Jinping called for “all-out” search efforts, emphasizing the need for improved early warning systems to prevent secondary disasters (BBC).
Flash flood tears through Nepal, Tibet killing scores and
Ongoing Challenges and Uncertainties
Rescue teams face significant obstacles, including blocked roads and helicopter landing restrictions in areas like Syapru Besi and Timure. Nepal’s Tourism Board CEO Hikmat Singh Ayer reported 403 people unaccounted for, with many foreign tourists still missing (CBS News). Chinese media cited 558 missing on the Tibet side, with 260 foreigners among them (CBS News). Markets have disappeared, and a critical artery for commerce between China and Nepal has also now been damaged, Fisher said, highlighting the economic ripple effects. As of August 28, the full scale of the disaster remains unclear, with authorities urging those near the Bhote Koshi River to relocate to higher ground (CBS News). Hundreds of travellers are missing, including at least 291 foreign tourists, after a flash flood swept away buildings on the Nepal-Tibet border. Aerial footage showed multi-storey buildings partially submerged by the muddy floodwaters, and a valley filled with dust and smoke. Nepal’s foreign minister says preliminary reports show it may have been caused by an earthquake triggering an avalanche, which lead to flash floods.
As rescue operations continue, the focus remains on locating the missing and assessing long-term damage to infrastructure and livelihoods.
