2026年8月26日上午10时30分许，山洪与泥石流冲向中尼边贸口岸吉隆口岸 1。尼泊尔与西藏边境喜马拉雅地区也发生大规模泥石流和山洪 2。截至8月26日20时，西藏日喀则市吉隆县一侧的泥石流灾害已造成3人遇难、265人失联 13。另有报道称西藏泥石流共造成558人失踪 5。在尼泊尔一侧，各方报告的死亡人数存在差异：有报道指出至少160人死亡，尼泊尔警方已找到157具遗体 2；另有报道称至少157人死亡 4；还有消息称至少162人死亡 5。在游客失联方面，尼泊尔旅游委员会披露山洪造成384名游客失联，其中包括93名尼泊尔游客，其余为外国籍游客 1；尼泊尔旅游业部报告有403名游客下落不明，其中341人为外国公民 4；另有报道显示至少403名游客失联，其中341人为外国人 2。此外，韩国外交部表示有8名韩国人下落不明，另有10人被困 1。失踪外国人包括142名印度人、33名英国人、47名美国人、34名澳大利亚人、24名加拿大人等 2。尼泊尔方面亦有至少28名警察失踪 2。
关于此次灾害的成因，专家研判认为，主要物源区位于尼泊尔境内蓝塘里壤峰北坡一带，由高位冰岩体失稳崩塌引发，与气候变暖导致冰川融化及降水增多密切相关 3。卫星图像显示，约5200米海拔处一大段冰川断裂并坠落超过1200米 4。初步证据表明，高处冰川崩塌引发冰岩雪崩，可能在距尼藏边境约20公里上游处堵塞河道形成临时堰塞湖后溃决，导致了“级联灾害” 4。美国地质调查局最初报告发生4.4级地震，后更新为5.2级山体滑坡 2。尼泊尔外长Shishir Khanal称地震可能引发山体滑坡并堵塞河流，尼泊尔灾害管理部门则根据卫星数据指出边境发生了“雪岩滑坡” 2。
灾害导致中尼边境基础设施严重受损。数十米高的吉隆口岸国门被吞没，日喀则市发布情况通报称，我方一侧通往口岸的道路、通信、电力均已中断 1。洪水于当地时间周三上午9时左右袭击博特科西河系统，特里苏里河在一个监测点30分钟内上涨达9米 4。至少19座公路桥和约40公里道路被损毁或冲走，连接贝特拉瓦蒂与中尼边境热苏瓦加迪口岸的42公里公路多处被毁 4。面对灾情，西藏政府动员近800名应急人员和150辆车参与救援，尼泊尔和中国西藏当局共动员数百名救援人员及车辆、搜救犬和快艇展开搜救 2。联合国秘书长古特雷斯表示，联合国团队正动员物资和人员支援尼泊尔 2。但由于持续降雨，救援难度进一步加大 1。专家同时警告，上游河道堵塞可能引发第二次洪水 2。
吉隆—拉苏瓦堡口岸承担着60%以上的中尼贸易量 1。2024年，该口岸监管进出口货物贸易额达42.48亿元，位居西藏各口岸首位，占中尼贸易总额近三成 3。值得注意的是，这已是吉隆沟在一年零四十九天内第二次被山洪泥石流截断 3。一年前的2025年7月8日，同一区域曾因冰湖溃决引发山洪泥石流，导致17名中方人员失联，中尼友谊桥被冲毁 3。
On August 26, 2026, massive mudslides and flash floods struck the Himalayan region along the China-Nepal border, causing hundreds of casualties and leaving many missing 125. The disaster severely impacted the Gyirong Port on the Chinese side and the northern border areas of Nepal, including Rasuwa County 123. Casualty figures vary among different reports: Chinese official media and the Shigatse municipal government reported that as of 8:00 p.m. on August 26, the mudslide on the Tibetan side had killed 3 people and left 265 missing 13, whereas AP News stated that the mudslide in Tibet resulted in 558 people missing 5. On the Nepalese side, the death toll is reported to be at least 157 to 162, with Nepalese police having recovered 157 bodies 245.
A large number of tourists are among the missing. Nepal's Ministry of Tourism and the Nepal Tourism Committee reported that at least 403 tourists are unaccounted for, including 341 foreign citizens 24, while another report from the Nepal Tourism Committee mentioned 384 missing tourists, comprising 93 Nepalese and the rest foreign nationals 1. The missing foreigners include 142 Indians, 47 Americans, at least 34 Australians, 33 Britons, and 24 Canadians 24. Additionally, the South Korean Ministry of Foreign Affairs stated that 8 South Koreans are unaccounted for and 10 are trapped 1, and at least 28 Nepalese police officers are also missing 2.
Experts indicate that the disaster was not caused by ordinary rainfall but was a "cascading hazard" 4. The primary source area of the disaster is located on the northern slope of the Langtang Lirung Peak in Nepal, triggered by the instability and collapse of high-altitude ice and rock masses, which is closely related to glacier melting and increased precipitation caused by climate warming 3. Satellite imagery shows that a large section of glacier at an altitude of about 5,200 meters fractured and fell over 1,200 meters, and the resulting avalanche likely blocked the river about 20 kilometers upstream from the Nepal-Tibet border, forming a temporary barrier lake that subsequently burst 4. Nepalese Foreign Minister Shishir Khanal noted that an earthquake might have triggered landslides and blocked the river 2. The US Geological Survey initially reported a 4.4 magnitude earthquake before updating it to a 5.2 magnitude landslide 2. Furthermore, Nepal's disaster management department stated that satellite data indicated a "snow-rock avalanche" at the border 2.
The flash floods hit the Bhote Koshi river system at around 9:00 a.m. local time on Wednesday, with the Trishuli River rising by 9 meters in just 30 minutes at one monitoring point 4. The gate of the Gyirong Port, which is tens of meters high, was swallowed, and roads, communications, and power supplies on the Chinese side leading to the port were completely cut off 1. In Nepal, at least 19 highway bridges and about 40 kilometers of roads were destroyed or washed away, including multiple sections of the 42-kilometer highway connecting Betrawati and the Rasuwagadhi border port 4. Notably, this is the second time in a year and 49 days that the Gyirong Valley has been severed by flash floods and mudslides; previously, on July 8, 2025, an outburst flood from a glacial lake in the same area left 17 Chinese personnel missing and destroyed the China-Nepal Friendship Bridge 3.
Continuous rainfall has increased the difficulty of rescue operations, but authorities have mobilized extensive resources 12. The Tibetan government has deployed nearly 800 emergency personnel and 150 vehicles for the rescue, and UN Secretary-General António Guterres stated that UN teams are mobilizing supplies and personnel to support Nepal 2. The affected Gyirong-Rasuwa border port is a crucial trade hub, handling over 60% of the China-Nepal trade volume 1. In 2024, the supervised import and export trade volume at the Gyirong Port reached 4.248 billion yuan, ranking first among all ports in Tibet and accounting for nearly 30% of the total China-Nepal trade 3.
