Flight chaos widens as Anak Krakatau ash grounds Jakarta-Darwin services

Indonesia's disaster mitigation agency (BNPB) reported that volcanic ash from Anak Krakatau, which has been erupting since late Friday, has spread across Lampung province on Sumatra and Banten province on Java. The ash was detected at the airport early Sunday, prompting the extension of a flight suspension that had originally been scheduled to end at 5:30am.

"BNPB urges the public to remain calm while increasing vigilance," said spokesperson Berton Panjaitan. "In the event of ashfall, people are advised to wear masks and eye protection, reduce outdoor activities, cover water sources and exercise caution when driving, as volcanic ash can reduce visibility."

Local media outlet Kompas reported that several schools cancelled activities on Saturday, with students and residents suffering eye irritation from the ash, and fishermen cancelling fishing trips due to the eruption. The disaster mitigation agency stated on Saturday that there was no imminent risk of tsunami from the volcano.

Why This Matters

Travellers between Jakarta and Australia face significant disruption, with dozens of flights cancelled and no clear timeline for normalisation.
The event highlights the vulnerability of aviation infrastructure to volcanic ash, which can damage jet engines and compromise safety.
Ashfall is causing public health and economic impacts on nearby communities, including eye irritation, school closures, and lost income for fishermen.

Background

Anak Krakatau, or "Child of Krakatau," is a volcanic island that emerged from the caldera of the infamous Krakatau volcano after its catastrophic 1883 eruption. The volcano has been frequently active in recent decades. A major eruption in December 2018 triggered a tsunami that killed hundreds of people along the coasts of Sumatra and Java. The current eruption began late on Friday, and volcanic ash was detected at Jakarta's main airport early on Sunday.

Key Perspectives

Indonesian authorities (BNPB and Transportation Ministry): Focused on public safety, urging calm and vigilance, advising ash-affected residents to wear masks and eye protection, while managing the extended flight suspension and monitoring ash dispersal. Airlines and passengers: Facing operational disruptions; 209 flights cancelled including international services, with knock-on cancellations on Jakarta-Australia routes. Passengers seek rebooking and compensation options. Local communities: Experienced eye irritation, school closures, and cancelled fishing trips; economic and daily life impacts from ongoing ashfall.

What to Watch

Whether the flight suspension at Soekarno-Hatta will be extended further as ash dispersal patterns evolve.
Updates from Indonesia's meteorological and volcanology agency on Anak Krakatau's activity level.
Potential for ash to affect other regional airports or flight paths across Southeast Asia and Australia.
