Anak Krakatau Eruption Halts Eight Indonesian Airports, Including Jakarta's Main Hub

Anak Krakatau erupted on 5–6 September 2026, sending ash to 15,000 metres over Java and Sumatra. Indonesia halted eight airports including Jakarta's Soekarno-Hatta, as ash can damage jet engines and scour windscreens. Lava and booming sounds were heard 700 km away. The disruption stranded over 22,000 passengers and cancelled 209 flights across routes to Singapore, Doha, Sydney, and Kuala Lumpur.
