In short
- Volcanic ash prompted temporary airport closures in Indonesia on September 6, including at Jakarta’s main gateway, as authorities monitored changing conditions.
Volcanic ash from Anak Krakatau disrupted air travel in Indonesia on September 6, 2026, prompting temporary closures at four airports, including Soekarno-Hatta, the main international gateway serving Jakarta.
Indonesia’s meteorology agency, BMKG, said aviation notices covered Soekarno-Hatta, Halim Perdanakusuma, Radin Inten II and Budiarto at different times. It cautioned that operating conditions could change as the ash moved and aviation safety information was updated.
Satellite analysis at 08:00 Western Indonesian Time on September 6 identified two areas of volcanic ash affecting parts of Java, Sumatra and nearby waters. BMKG said ash was present at altitudes reaching 20,000 feet in one area and 50,000 feet in another.
The disruption followed volcanic activity that began on September 4. The agency said it was maintaining round-the-clock monitoring of effects on the atmosphere, aviation and waters around the Sunda Strait.
The notices establish temporary interruptions, rather than a confirmed reopening timetable. Travellers should check their airline’s latest flight status before heading to the airport.
