阿纳克喀拉喀托火山于周日早上3时53分发生喷发，持续30秒，喷出的火山灰影响了雅加达及苏门答腊岛南部地区1。喷发产生了两股火山灰云：第一股高度达20000英尺（6100米）向东北方向漂移，第二股高度达50000英尺（15200米）向西及西北方向移动1。
受火山灰影响，雅加达苏加诺-哈达国际机场从早上5时30分至9时30分暂停了所有航班运营1。据官方通报，距火山活跃火山口至少3公里范围为安全警告距离，最近的居民地距离火山超过16公里1。本次喷发未造成人员伤亡，也未发布疏散令1。
2018年阿纳克喀拉喀托火山曾发生爆炸性坍塌，引发海啸，造成苏门答腊岛和爪哇岛至少430人丧生1。
Anak Krakatau volcano erupted on Sunday morning at 3:53 a.m., with the eruption lasting 30 seconds 1. The volcanic ash from the eruption affected Jakarta and southern Sumatra, prompting authorities to take immediate action 1. In response, Soekarno-Hatta International Airport in Jakarta suspended all flight operations from 5:30 a.m. to 9:30 a.m. 1. No casualties were reported from the eruption, and no evacuation orders were issued 1.
The eruption produced two distinct ash columns, with the first reaching 20,000 feet (6,100 meters) and drifting toward the northeast, while a second column climbed to 50,000 feet (15,200 meters) and moved westward and northwestward 1. The nearest populated areas are situated more than 16 kilometers (10 miles) from the volcano, while the minimum safe distance from the active volcanic crater is at least 3 kilometers (1.9 miles) 1. This latest activity recalls the December 2018 catastrophic eruption, when an explosive collapse of Anak Krakatau triggered a tsunami that killed at least 430 people across Sumatra and Java 1.
