印度尼西亚的阿纳克火山在2026年9月初发生了持续超过24小时的剧烈喷发1。此次喷发中，火山灰东侧升至6000米高空，西侧最高达到15000米，约相当于5万英尺1。NASA卫星在9月5日捕捉到了火山灰羽流扩散的景象1。
喷发对区域交通和空气质量造成了严重影响1。共有8个机场临时关闭，导致近3000架航班中断运营1。喷发影响了包括雅加达在内的多个地区的空气质量1。到9月8日，机场逐步恢复运营1。截至9月8日，火山警报级别仍处于二级，该级别自7月初以来一直保持1。
In early September 2026, Indonesia's Anak Krakatau volcano unleashed a powerful eruption that lasted more than 24 hours, sending volcanic ash to extraordinary heights.1 The ash column rose approximately 20,000 feet on the volcano's eastern side, while reaching nearly 50,000 feet on the western side.1 NASA satellite imagery captured the expansive ash plume as it dispersed across the region on September 5.1
The eruption severely disrupted regional aviation and air quality. Eight airports were forced to temporarily close their operations, and nearly 3,000 flights were cancelled or delayed as a result of the ash clouds.1 The air quality in Jakarta and other parts of West Java was significantly affected by the volcanic emissions.1 Airports resumed normal operations by September 8, though the volcano remained at alert level 2, a status it has maintained since early July.1
