2026年8月26日，源于尼泊尔境内海拔5200米高山的冰岩崩引发泥石流，以每秒50米的速度奔袭22公里，跨越3400米高差后摧毁了西藏吉隆口岸，成为近年来中国遭遇的最严峻的跨境复合型灾害 1。吉隆口岸核心区泥石流堆积物平均厚度达4米，最高处达16米，泥石流冲击痕迹高达60米，五层高的"国门大楼"仅剩钢筋骨架 1。
截至9月5日18时，灾害共造成43人遇难、519人失联，成功救出2人，发现遗物993件 1。救援人员面临极端恶劣环境，道路、通信、电力瞬间中断，山体塌方频发，落石、滑坡、堰塞体等次生灾害时刻威胁其安全 1。在这些困难下，救援队伍坚持开展拉网式排查，在淤泥中陆续发现并妥善保存警用背心、警用帽子、婴儿护具、衣物、鞋子、项链、玩具、锅碗瓢勺等遗物 1。
A massive mudslide originating from Nepal's high-altitude glacial collapse on August 26, 2026, raced across 22 kilometers at speeds reaching 50 meters per second, leaving Tibet's Gyirong Port nearly completely destroyed in what represents one of China's most severe transnational compound disasters in recent years 1. The debris flow, triggered by an ice and rock collapse at 5,200 meters elevation in Nepal, descended across a 3,400-meter elevation difference before striking the port with devastating force 1.
As of September 5 at 6 p.m., the disaster had claimed 43 lives, left 519 people missing, and resulted in the successful rescue of 2 individuals 1. The mudslide deposits averaged 4 meters thick across the port's core area, with maximum accumulations reaching 16 meters, while impact scars reached heights of 60 meters—leaving only the steel framework of the five-story "National Gate Building" standing 1. Rescue personnel discovered 993 items scattered through the silt, including police vests, police caps, infant protective equipment, clothing, shoes, necklaces, toys, and kitchenware 1.
Rescue operations faced extraordinary challenges as communications, power, and road access were severed instantly, with ongoing landslides, rockfall, and barrier lake formation continuously threatening worker safety 1. Teams conducted systematic grid-pattern searches across the devastated landscape under extreme conditions, carefully recovering and preserving personal effects while working to locate missing individuals in an environment reshaped by the disaster's violent force 1.
