Story summary
A catastrophic flash flood occurred on August 26, 2026, on the Nepal-Tibet border, causing widespread destruction and loss of life. The disaster was triggered by a collapsed glacier, which sent massive amounts of water and debris downstream, resulting in the deaths of at least 273 people and leaving over 1,300 missing. The floodwaters swept through several communities, including Syapru Besi and Timure in the mountainous district of Rasuwa, with many villages and infrastructure destroyed. Rescue teams were deployed to search for survivors, but their efforts were hindered by the remote location and challenging terrain.
The disaster also affected Tibet, where a mudslide hit the land border crossing at Gyirong Port, causing major casualties and disruptions to transportation and communication networks. Chinese President Xi Jinping ordered "all-out" efforts to search for those missing and to strengthen monitoring and early warning systems to prevent similar disasters in the future.
The Nepal Tourism Board reported that 25 Canadians were among those missing, and officials warned of a high risk of secondary collapses or landslides as rain continued in the affected area. The disaster has highlighted the issue of rapidly melting Himalayan ice and the need for better preparedness and emergency response measures in the region.

Rescuers race to find trapped workers in hydropower plant tunnels after Nepal flooding
Multiple foreign teams assisting local rescuers as deaths climb past 900
Rescuers rushed Monday to reach workers believed to be trapped in tunnels at hydropower sites buried in mud after catastrophic flooding in Nepal and China, as the death toll continued to rise and increasingly desperate families search for their loved ones.
asserted
families → race → ones
The combined deaths in Nepal and China surpassed 900, with more than 4,700 people missing, and a private-sector association representing power companies said at least 900 workers have been unaccounted for from 12 hydropower projects damaged by the floods in Nepal's Rasuwa and Nuwakot districts.
asserted
workers → combine → districts
Mohan Kumar Dangi, president of the Independent Power Producers' Association, Nepal, or IPPAN, said there's an estimation of at least 500 of the 900 missing workers trapped in the tunnels, although authorities have provided varying numbers and said several foreign teams were assisting Nepali rescuers.
asserted
teams → say → rescuers
At least one expert said the tunnels offered enough space for people to take refuge and that some workers could have access to oxygen.
uncertain
workers → say → oxygen
But others warned that the chances of finding survivors were diminishing.
asserted
chances → warn → survivors
Dangi said some workers had managed to make contact and call for help when the disaster struck last Wednesday, and some others who managed to flee reported to authorities and relatives that many of their colleagues were still in the tunnels.
asserted
many → say → tunnels
But he said that, six days after the disaster, fears grew that some might have suffocated.
uncertain
some → say → disaster
"We are working in search and rescue of the stranded people from hills, settlements and river areas," said Brig. Gen. Raja Ram Basnet, Nepal's army spokesman.
asserted
Basnet → work → hills
Nepal's disaster agency said Monday that 903 deaths had been counted in that country, with 4,247 people, including 592 foreigners, missing.
asserted
people → say → foreigners
As of Sunday, Chinese authorities reported 16 deaths and 546 missing, and Chinese state media said 261 of the missing were foreigners, including over a hundred Nepalis.
asserted
261 → report → Nepalis
Trapped in tunnels
Workers shovelling mud from a flood-ravaged power station in Dhading, Nepal, told The Associated Press that the station is a key node for providing power to over 20,000 people in the region.
asserted
station → trap → region
The workers cleaning the power station said they hope that it is not rebuilt near the river.
asserted
it → clean → river
Rescue efforts are focused on people trapped in the gigantic tunnels built for controlling the waterflow to produce hydropower.
asserted
efforts → focus → hydropower
"The tunnels are built to access hydropower infrastructure and to divert water — an essential step to generate energy.
asserted
tunnels → build → energy
These tunnels are big enough to drive trucks through," said Jakob Steiner, a geoscientist at the University of Graz in Austria who is currently based in Dhaka, Bangladesh.
asserted
who → drive → Dhaka
"There is enough place for people to take refuge safely inside and from what we understand they have managed to get oxygen to some of those stuck inside and are trying to rescue them now.
asserted
they → be → them
It's a race for time though as people need food and water.
asserted
people → need → food
"
In the Upper Trishuli-1 Hydropower Project, in the hard-hit Rasuwa district, at least 576 were missing, Dangi said, adding that around 300 of them were believed to be trapped inside the project's tunnel.
asserted
300 → hit → tunnel
Rescuers have been trying to find survivors for days, working through the rain.
asserted
Rescuers → try → rain
On the Chinese side, rescue and recovery efforts included rebuilding the road leading to Gyirong Port at the border between China and Nepal.
asserted
efforts → include → China
Trucks carried giant rocks as workers worked on repaving a portion of the road, state broadcaster CCTV showed Monday, next to rapidly rushing waters, which have been made more powerful by rains in the past couple of days.
asserted
which → carry → days
The road is now under some two to three metres of water, hampering rescuers' ability to reach the border.
asserted
road → hamper → border
The repaving effort was just a little over a kilometre from the border, CCTV said.
asserted
CCTV → say → border
Although some rescue teams have managed to reach the border, that represented only a portion of the force.
asserted
that → manage → force
Rescuers search for thousands following deadly Nepal-China flood
Scientists fear Nepal's disaster is just a glimpse of the carnage climate change could cause
Two days after the disaster, Maraval Nagappan travelled to Nepal to search for his son, who was among the missing.
uncertain
who → search → missing
He visited rescue centres and morgues and went as far as 40 kilometres from where his son was believed to have been, but found no sign of him.
asserted
son → visit → him
His son, Sathya Narayan had been leading a group of 49 Indian devotees who were returning from Mount Kailash — a sacred site in southwestern Tibet.
asserted
who → lead → Tibet
The group has been missing since floodwaters swept through a Chinese immigration complex where they were waiting to cross into Nepal.
asserted
they → miss → Nepal
Nagappan, who owns the Chennai-based travel company that organized their pilgrimage, and said the group had been expected to complete immigration formalities and leave for Nepal within about two hours.
asserted
group → own → hours
Instead of making the crossing, they were caught in the flood, Nagappan said.
asserted
Nagappan → make → flood
The pilgrimage had begun Aug. 14.
asserted
pilgrimage → begin → ?
"I haven't heard from my son since then.
asserted
I → hear → son
I don't know whether he is alive or dead," he told The Associated Press, but he said he hadn't given up on hearing from his son.
asserted
he → know → son
Surveillance footage showed water surging through the immigration complex at the border as people scrambled to escape.
asserted
people → show → border
Nagappan said some of those seen fleeing were members of his son's group and were identified by the clothes they were wearing.
asserted
they → say → clothes
Wednesday's flash floods started after a glacial collapse high in the Himalayan region.
asserted
floods → start → region
Scientists who studied satellite images said bedrock underneath a glacier high in the Himalayan region had collapsed, taking part of the glacier with it.
asserted
bedrock → study → it
The rockfall was so extreme that it registered as a magnitude 5.2 seismic event.
asserted
it → register → event
The rocks and melted water then swelled the rivers in the valleys below, causing a torrent of water that swept buildings, bridges and earth downstream in Tibet and Nepal.
asserted
that → melt → Tibet
