Indonesian airports shut as Anak Krakatau volcano spews ash

Eight Indonesian airports have halted flight operations as ash from the active Anak Krakatau volcano continues to blanket surrounding regions. The airport shutdowns represent a significant disruption to air connectivity in one of Southeast Asia's busiest travel corridors.

Anак Krakatau, located in the Sunda Strait between Java and Sumatra, has been regularly ejecting volcanic material into the atmosphere. The ash dispersal has created hazardous conditions for aircraft operations, prompting aviation authorities to implement precautionary closures across multiple facilities in the region.

The affected airports have suspended scheduled flights pending improvements in air quality and visibility. Passengers have faced considerable delays and cancellations as carriers work to accommodate displaced travellers through alternative routes.

Volcanic ash poses a significant risk to aircraft engines and avionics systems, making airport closures necessary safety measures. Authorities continue to monitor atmospheric conditions and volcano activity levels to determine when normal operations can resume.

The incident underscores the vulnerability of regional air transport infrastructure to natural hazards in Indonesia's geologically active zone. Authorities have urged travellers to remain in contact with their airlines for updates on flight status and rebooking options.
