2026年8月26日，尼泊尔境内蓝塘里壤峰北坡海拔5200米处发生冰岩崩，形成的巨型泥石流沿东林藏布河运动，摧毁了中国西藏吉隆口岸0.7平方公里范围内的27处建筑及附属设施 1。灾后河道宽度从约30米拓大到约350米 1。
成都理工大学范宣梅团队对灾害成因的研判结果与官方调查结论一致，指出全球变暖加速高山冰冻圈消融及极端“厄尔尼诺”事件是灾害主要诱因 1。联合国于同年10月21日预警本轮厄尔尼诺强度或创历史纪录，全球变暖与极端天气共同增加了山体失稳风险 1。随着人类活动向高山区扩展，此类由气候驱动的地质灾害对基础设施和人员构成的风险日益增加 1。
On August 26, 2026, a catastrophic ice-rock collapse occurred on the north slope of Langtang Lirung Peak in Nepal at an altitude of 5,200 meters 1. The resulting massive debris flow traveled along the Donglin Zangbu River, causing severe destruction across the border in China’s Tibet Autonomous Region 1. At the Gyirong port, 27 buildings and associated facilities within a 0.7-square-kilometer area were leveled to the ground 1.
Experts from the Fan Xuanmei team at Chengdu University of Technology determined that the river channel width expanded dramatically from approximately 30 meters to about 350 meters following the disaster 1. Their assessment of the causes aligns with official investigation results 1. Scientists identify the accelerating melting of the alpine cryosphere due to global warming as a primary trigger for such events 1. This hazard is compounded by extreme weather patterns, specifically El Niño events 1. On October 21, the United Nations issued a warning that this current El Niño cycle could reach record-breaking intensity 1. As human activities continue to expand into high-mountain regions, climate-driven geological disasters pose an increasing risk to infrastructure and personnel 1.
