A catastrophic natural disaster triggered by a glacial collapse on the Nepal-China border has left a trail of destruction, killing more than 1,000 people and leaving thousands unaccounted for, with cross-border rescue efforts underway to reach hundreds of workers trapped in blocked hydropower project tunnels.
The disaster struck last Wednesday, when a sudden glacial collapse sent an unprecedented surge of ice, rock, and mud crashing down into river valleys below. The resulting flash floods and landslides devastated communities on both sides of the border, blocking roughly a dozen hydropower project tunnels with debris and leaving more than 900 construction workers trapped inside, according to Nepalese authorities.
As of the latest update, Nepalese disaster management officials confirm 903 people have been killed across the country, with another 4,247 still listed as missing. On the Chinese side of the border in the Tibet Autonomous Region, official records show at least 16 people have died, and 546 remain unaccounted for. Chinese state media also reports that 261 foreign nationals from 23 countries are among those missing in Tibet. In addition to the trapped hydropower workers, around 500 employees of Nepal’s Truck and Container Association are also still missing, local media reports confirm.
The International Committee of the Red Cross estimates that more than 90,000 people have been displaced or otherwise affected by the disaster, which Chinese authorities have linked to the broader impacts of climate change on glacial systems in the Himalayas. Nepalese Prime Minister Balendra Shah has described the event as an “unprecedented and devastating natural disaster” that has stretched the country’s emergency response capacity to its limit.
Nepalese authorities have launched a full-scale emergency operation to reach trapped workers and recover victims, with nearly 21,000 security personnel and volunteer rescue workers working around the clock to clear debris and open access routes. Army spokesperson Raja Ram Basnet noted that the massive volume of mud and rock debris blocking access to the tunnels presents an extraordinary operational challenge. While many damaged roads have been cleared for traffic, roughly 40 kilometers of highway have been completely washed away, slowing the delivery of emergency supplies and rescue equipment to affected areas.
In response to the crisis, Nepal has accepted specialized rescue support from both China and India, drawing on regional expertise to reach workers trapped in the blocked tunnels. China has deployed nine professional tunnel rescue experts to Nepal and shared real-time satellite imagery of the disaster zone to help Nepalese teams plan operations. China has also committed more than 2,100 rescue workers and allocated 220 million yuan (approximately 33 million USD) to disaster relief efforts, with emergency supplies airdropped to cut-off areas and Chinese soldiers using specialized detection equipment to locate potential survivors. Chinese President Xi Jinping has issued multiple calls for maximum rescue efforts to locate and assist missing people.
Difficult conditions, including unstable weather and the threat of outburst flooding from a newly blocked glacial lake, have forced multiple pauses in rescue operations. However, local authorities confirmed that weather conditions improved on Monday, allowing search and rescue work to resume across the disaster zone.
In Nepal’s Chitwan district, where mass burials for recovered victims have been held, grieving families are still searching for information on missing loved ones. Hundreds of unidentified remains have been interred in shallow mass graves due to hot, humid weather that accelerates decomposition, and mortuaries in the capital Kathmandu are operating beyond capacity, forcing families to search for missing relatives across multiple city hospitals.
