Tibet Mudslide Kills 7, 554 Missing in Himalayan Disaster
A catastrophic mudslide triggered by a glacier collapse in the Himalayas has killed at least 7 people in Tibet’s Gyirong County with 554 reported missing, according to Xinhua News. The disaster struck Gyirong Port on the China-Nepal border on Wednesday morning, with rescue teams racing against time amid threats of secondary disasters from an unstable barrier lake upstream.
The Disaster
The mudslide was triggered by a glacier collapse on the Nepalese side of the border at an elevation of approximately 5,200 meters. The ice-rock avalanche plunged roughly 1,200 meters onto the valley floor, gathering rock and sediment before striking the Lhende River about 20 kilometers northeast of the border crossing. According to Al Jazeera, the debris flow traveled with devastating speed, taking only about seven minutes between the onset of the ice avalanche and the mudslide hitting the port.
Guo Zhaocheng, an expert with China’s Ministry of Natural Resources, noted that such a narrow window highlights the extreme difficulty of detecting and issuing early warnings for high-altitude, long-distance chain disasters, as reported by Xinhua English.
The disaster struck during daytime working hours when crowds were present at the port, a bustling commercial hub that serves as a national first-class land port and key China-Nepal border trade channel. The port and surrounding valley were completely submerged in mud, with the joint inspection building, commercial warehouses, and the Resuo Bridge destroyed.
Casualties and Missing Persons
As of early Saturday, the death toll in Tibet stood at 7 with 554 people missing, including approximately 260 foreign nationals. Many of the missing were pilgrims traveling toward Mount Kailash and Lake Mansarovar, according to the Chinese Ministry of Foreign Affairs. In a press conference, MFA Spokesperson Lin Jian confirmed that China’s rescue efforts treat Chinese and foreign nationals equally and that Beijing is in close communication with relevant embassies.
The disaster has inflicted even more severe casualties in Nepal, where at least 579 people have been confirmed dead with 1,924 missing, including 517 foreign nationals. Nepal’s Department of Tourism reported that 668 tourists from 34 countries remain out of contact, with India (177), the United States (90), Australia (34), the United Kingdom (33), and Canada (25) among the most affected nationalities.
Rescue Operations and the Barrier Lake Threat
More than 2,141 rescue personnel have been deployed to the disaster zone, including 681 firefighters with 113 vehicles, 13 rescue dogs, and 47 drones, along with approximately 500 PLA and People’s Armed Police personnel. According to CGTN, relief supplies including 20 tonnes of highland barley, 50 tonnes of rice, and over 1,100 tents have been delivered to Gyirong Town.
However, rescue operations have been severely complicated by a barrier lake that formed upstream of the port. The lake, holding over 2 million cubic meters of water at an elevation roughly 1,000 meters above Gyirong Port, posed an imminent threat of breaching and triggering new flash floods. As Al Jazeera reported, rescue teams were forced to temporarily halt operations on Friday when the lake began to overflow, before resuming once the risk was deemed manageable.
A five-person observation post is monitoring the lake in real-time, while a military drone from the PLA Western Theater Command spotted an avalanche sending ice debris into the lake, triggering immediate warnings and emergency evacuations. An Air Force official told Xinhua that the drone has conducted extensive reconnaissance for three consecutive days to assess secondary disaster risks.
Political and International Response
Chinese President Xi Jinping chaired a CPC Politburo meeting on Friday to coordinate rescue efforts, during which leaders observed a moment of silence for the victims. The meeting emphasized scientific search plans, all-out rescue of missing Chinese and foreign nationals, and provision of emergency aid to Nepal, as CGTN reported. Premier Li Qiang traveled to the disaster area on Thursday to oversee operations.
The international community has mobilized significant support. India sent rescue aircraft with approximately 10 tonnes of emergency supplies, while the United States provided $500,000 in assistance and a disaster response adviser. Australia announced $3.6 million in aid, Canada pledged CAN$5 million, and the European Union activated its Copernicus Emergency Management Service. The United Nations allocated $2 million from its Central Emergency Response Fund, and the IFRC released 1 million Swiss francs in emergency funding.
Why So Destructive?
Experts point to a combination of extreme terrain, massive debris volume, and the sudden nature of the triggering event. Xu Qiang, president of Chengdu University of Technology, told CGTN that the elevation difference of several thousand meters and steep slopes allowed the mass of ice, rocks, and sediment to rapidly gain speed as it moved downhill. The volume of material is estimated at tens of millions of cubic meters, with a preliminary affected area of 15 to 20 square kilometers.
Climate Change Context
Scientists note that glaciers across the Hindu Kush Himalaya range lost ice 65 percent faster between 2011 and 2020 than during the previous decade, with Nepal’s glaciers losing close to one-third of their ice volume in roughly three decades. Satellite observations showed unusually warm conditions around the affected glacier before the collapse. While a direct link between climate change and this specific event has not been established, experts warn that glacial disasters on the “Third Pole” are becoming more frequent, more widespread, and more destructive.
What’s Next
Rescue operations continue as teams push toward the core disaster area, with professional rescue teams reaching the site on Friday afternoon. However, the meteorological department forecasts light to moderate rain or thunderstorms across most of Gyirong County until Sunday, which could trigger flash floods and landslides in vulnerable areas. Authorities are also monitoring the barrier lake, with an additional 3 million cubic meters of water expected to enter by September 1. The death toll is expected to rise as rescuers reach areas that remain inaccessible.
