印度尼西亚火山活动引发严重航空运输中断。喀拉喀托之子火山持续喷发，导致包括首都雅加达苏加诺—哈达国际机场在内的8座机场关闭至当地时间9月6日午夜1。受影响的这些机场共有1558个航班延误，约17万名旅客滞留1。其中苏加诺—哈达国际机场单独就有963个航班受影响，包括453个抵达航班和510个出发航班1。
火山灰构成重大航空安全隐患。火山灰可能导致飞机发动机叶片磨损、推力丧失甚至熄火1。印尼交通部长杜迪·普尔瓦甘迪表示，政府采取保守态度，"因为风向高度不确定"2，这促使当局决定延长机场关闭时间。同日，喀拉喀托之子火山、塞梅鲁火山、伊利勒沃托洛科火山和伊布火山均发生喷发1。
为应对火山灾害，受火山灰影响地区的学校已转为在线教学2。南苏门答腊省帕卡尔阿拉姆市的阿通邦苏机场于周一上午恢复正常运营2。
A series of volcanic eruptions in Indonesia has forced the closure of multiple airports, stranding hundreds of thousands of passengers and disrupting air travel across the archipelago. The Anak Krakatau volcano has erupted continuously for 25 hours, with the eruption sound audible up to 700 kilometers away 2. Eight airports have been shut down until midnight on September 6 local time, affecting a combined 1,558 flight delays and stranding approximately 170,000 passengers 1. Among the affected facilities, Jakarta's Soekarno-Hatta International Airport alone saw 963 flights impacted, comprising 453 arriving and 510 departing flights 1.
The volcanic activity has prompted authorities to extend precautionary measures beyond aviation. Transport Minister Dudi Purwagandi stated that the government is "taking a conservative approach because wind direction is highly uncertain," explaining the decision to keep seven airports closed until midnight rather than reopening them earlier 2. Meanwhile, Atung Bangsul Airport in Palembang, South Sumatra, resumed normal operations on Monday morning 2. In addition to airport closures, schools in volcanic ash-affected areas have been ordered to switch to online instruction as a protective measure 2. According to reports, volcanic ash poses a significant hazard to aircraft, potentially causing blade wear, thrust loss, or even engine failure 1. The eruption coincided with activity from several other volcanoes in the region, including Mount Semeru, Mount Ibu, and Mount Lewotololo, all of which erupted on the same day 1. Nearly 3,000 flights have been cancelled as a result of the volcanic disruptions 2.
