Four Indonesian Airports to Remain Closed Until 6 p.m. as Anak Krakatau Ash Disrupts Flights

Four Indonesian airports will remain closed to flight operations until 6 p.m. on Monday as ash from Mount Anak Krakatau continues to disrupt air travel, including around Jakarta.

PT Angkasa Pura Indonesia, which manages the affected airports through InJourney Airports, announced the extension. The closures cover Soekarno-Hatta, Halim Perdanakusuma, Radin Inten II and Husein Sastranegara airports. Passengers have been told to check their flight status with their airlines or contact the InJourney Airports Contact Center.

The latest disruption follows another Anak Krakatau eruption at 8:23 p.m. on Sunday. The eruption was not observed visually, but seismographs recorded it at a maximum amplitude of 58 millimeters and a duration of 44 seconds.

Volcanic ash spread toward areas around Jakarta on Monday morning, according to Indonesia’s Meteorology, Climatology, and Geophysics Agency. In an assessment issued at 6 a.m., the agency identified two ash-dispersion clusters. It based the analysis on information from the Center for Volcanology and Geological Hazard Mitigation, the Darwin Volcanic Ash Advisory Center and Himawari-9 RGB satellite imagery.

“Based on information from PVMBG and VAAC Darwin, as well as an analysis of Himawari-9 RGB imagery at 06:00 WIB on September 7, 2026, two clusters of volcanic ash dispersion from Mount Anak Krakatau were identified,” the agency said. The continued ash spread prompted authorities to extend the flight suspensions while they monitor conditions and assess aviation safety.
