Core Event: Flight suspension at Soekarno-Hatta International Airport
On September 6, 2026 the Anak Krakatau volcano erupted at 3:53 a.m. local time, sending ash plumes over the Sunda Strait. Volcanic ash was detected at Jakarta’s Soekarno-Hatta International Airport, prompting a suspension of all flight operations. The shutdown, initially set to end at 9:30 a.m., was later extended to 1:30 p.m. local time, affecting hundreds of flights and stranding thousands of passengers.
Background & Context
Anak Krakatau, “child of Krakatau,” emerged in the 1920s within the caldera left by the 1883 eruption. A partial collapse of its southwest flank in December 2018 triggered a tsunami that killed at least 430 people. The volcano’s alert level was raised to Level III on July 2 and has remained at the second-highest tier.
Data & Statistics
- Flights: Ministry of Transportation cited 209 flights (?22,800 passengers) disrupted; other outlets reported 301 flights (58 international).
- Aircraft: 170 aircraft remained parked on the apron overnight.
- Ash plumes: Satellite imagery identified two ash clouds—one rising to 6 km over Java and a second reaching 15 km over Sumatra and Banten.
- Other airports: Radin Inten II (Lampung), Halim Perdanakusuma (Jakarta) and several regional airports were temporarily closed.
- Local impact: Schools in Banten and Lampung cancelled classes; fishermen halted trips; residents were advised to stay at least 3 km from the crater.
Official Statements & Responses
Lukman F. Laisa, director general of civil aviation, said safety guided the decision to halt operations and warned of cascading effects on aircraft rotations and terminal capacity. The Directorate General of Civil Aviation coordinated with airlines, air navigation services and the meteorology agency to monitor the ash situation.
Berton Panjaitan, spokesperson for the National Disaster Management Agency (BNPB), urged the public to remain calm, wear masks and limit outdoor activity because ash can reduce visibility.
Lana Saria, head of Indonesia’s Geological Agency, cautioned that ash direction could change rapidly and advised travelers to follow transport-authority guidance. The agency reiterated that no imminent tsunami risk existed.
On-the-Ground Reports
Passengers faced long queues to claim refunds and retrieve baggage. A Singaporean traveler who arrived on September 3, 2026 said he received no updates and assumed his flight was delayed or cancelled. Another passenger heading to Samarinda reported his connecting flight was also cancelled, leaving him to seek accommodation in Jakarta. Airport officials provided food, light refreshments and bus transfers to nearby hotels.
