Summary
Mount Anak Krakatau in Indonesia erupted for 25 hours continuously in September 2026, blanketing cities in volcanic ash and causing widespread disruption. Multiple airports closed, stranding more than 300,000 passengers, with flight cancellations affecting Jakarta for three days. The eruption transformed Sertung Island, eliminating vegetation and exposing non-vegetated material. Two new islands subsequently emerged in the water-filled caldera surrounding the volcano—one approximately 760 metres northwest and another about 495 metres southwest of Mount Anak Krakatau—though their formation mechanism and permanence remain under investigation. The volcano was placed at alert Level 2, with a three-kilometre exclusion zone established. Reports indicate that five journalists and three boat crew members were declared presumed dead after their vessel disappeared while covering the eruption. The incident prompted review of aviation safety protocols in light of volcanic ash hazards.
