Eruption and immediate airport closures
Late on September 4 2026, Anak Krakatau erupted, sending ash toward Jakarta. AirNav Indonesia issued NOTAMs that closed the airspace of eight airports, including Soekarno-Hatta International (CGK) and Halim Perdanakusuma (HLP). The closures, set for September 5, were extended as ash concentrations persisted.
Scope of disruption
- Airports affected: Eight facilities across Java and Sumatra, with four major commercial airports shut.
- Flights: Between 209 and nearly 3,000 flights were canceled or delayed, including about 900 international services.
- Passengers: More than 170,000 travelers were stranded.
- Ash plume heights: BMKG recorded ash reaching 6,000 m (?20,000 ft) on the Java side and 15,000 m (?50,000 ft) on the Sumatra side.
- Alert level: The volcano remained on Alert Level III.
Government and aviation authority response
The Ministry ordered inspections of aircraft, runways and taxiways before resuming operations and instructed pilots to stay aware of restricted airspace. The Directorate General of Civil Aviation, led by Lukman F. Laisa, emphasized that “safety remains our top priority in every operational decision.”
The disaster-mitigation agency Badan Nasional Penanggulangan Bencana (BNPB) launched cloud-seeding to wash ash from the city, and its chief Suharyanto urged the public to wear masks and limit outdoor activity.
Passenger experiences on the ground
Travelers faced long queues, uncertain refunds and makeshift accommodations. Conservationist Jo Shaw noted, “Everyone seems to be racking their brains [figuring alternative transportation options].” Indonesian-born passenger Finna (46) described the “frenzy” at the departure hall and spent the night on intercity trains before reaching Jakarta on Monday.
Conflicting reports and gaps
- Passenger counts: BBC cites >340,000 stranded; Al Jazeera reports >270,000; CNN and the transport ministry mention 170,000.
- Flight cancellations: AP and BBC note ~209 flights; other outlets list between 1,558 and 2,961.
- Ash plume measurements: Reports vary between metric and imperial figures.
These discrepancies stem from differing reporting windows and the evolving ash cloud. No official consolidated figure had been released as of September 8 2026.
