尼泊尔博特科西河谷发生大规模冰川崩塌引发的泥石流和洪水 1。这场灾害造成超过150人死亡、数百人失踪，其中至少34名澳大利亚人失踪 1。泥石流和洪水沿博特科西河谷蔓延超过170公里 1。到达吉隆口岸时，碎片墙估计高达30米，地震仪记录到相当于4.4级地震的震动能 1。
早期分析表明，气候变化导致喜马拉雅地区冰川加速消融和永久冻土退化，引发山体滑坡并导致冰川突然崩塌 1。去年同一地区发生较小洪水造成9人死亡，2024年尼泊尔曾发生冰川湖溃决洪水 1。建立有效的早期预警系统对降低此类气候相关灾害风险至关重要 1。绿色气候基金去年宣布为尼泊尔提供更好的监测系统资金 1。
A massive glacial collapse in Nepal's Bhote Koshi River valley triggered mudslides and floods, resulting in over 150 deaths and hundreds of missing persons 1. The mudslides and floods traveled more than 170 kilometers along the river valley, with the wall of debris estimated to be up to 30 meters high when it reached the Gyirong Port 1. Seismographs recorded seismic energy equivalent to a 4.4 magnitude earthquake 1. Among the missing are at least 34 Australian nationals 1.
Early analyses indicate that climate change accelerated glacial melting and permafrost degradation across the Himalayas, triggering landslides and a sudden glacial collapse 1. This follows a glacial lake outburst flood in Nepal in 2024 and a smaller flood in the same area last year that claimed nine lives 1. The Green Climate Fund announced funding last year to help Nepal establish better monitoring systems, highlighting the critical need for effective early warning systems to mitigate the risks of such climate-related disasters 1.
