Anak Krakatau Eruptions Close Jakarta's Soekarno-Hatta and Seven Other Airports
Two eruptions from Anak Krakatau in the Sunda Strait on the morning of Sunday, 6 September 2026 sent volcanic ash drifting across western Indonesia, triggering the closure of Soekarno-Hatta International Airport in Jakarta and at least seven other airports. By Sunday evening, 467 flights at Soekarno-Hatta alone had been affected, leaving around 150,000 passengers stranded or rerouted. The airport was scheduled to remain shut until 11:59 pm local time.
What Happened
Indonesia's Geological Agency recorded the first eruption at 3:53 am, lasting roughly 30 seconds, followed by a second at approximately 6:53 am that lasted around 16 seconds. Monitoring cameras captured lava flares during both events. Satellite tracking identified two separate ash clouds: one rising to about 20,000 feet and a second, more powerful plume reaching approximately 50,000 feet that spread across several provinces and surrounding waters.
Ash fall was reported in parts of Jakarta and Lampung. In response, AirNav Indonesia closed airspace around Soekarno-Hatta and Halim Perdanakusuma airports in the Jakarta area, as well as Radin Inten II Airport in Lampung and five additional airports. Operations were also disrupted at Bali's I Gusti Ngurah Rai International Airport and airports in Medan, extending the impact well beyond the immediate eruption zone.
Safety Situation on the Ground
No deaths or injuries were reported, and authorities did not issue evacuation orders. Residents and visitors were advised to keep a distance of at least 3 kilometres from the crater. The nearest settlement sits more than 16 kilometres away, providing a significant natural buffer. Officials cautioned that the volcano remains active and that ash, volcanic gases, and hot rocks continue to pose potential hazards. Indonesia's Geological Agency noted that activity at Anak Krakatau has been intensifying since July, with the 6 September eruptions being the strongest in that period.
Anak Krakatau has a significant place in Indonesia's geological history. The island emerged following the catastrophic 1883 Krakatau eruption. More recently, a 2018 eruption triggered a tsunami that killed at least 430 people across Java and Sumatra, a reminder of the serious secondary risks the volcano can generate.
Why it Matters for Hosts
Independent accommodation operators in Jakarta, Lampung, Bali, and Medan should treat volcanic disruption as a recurring operational risk, not a one-off event. The 6 September closures affected airports across a wide geographic arc, meaning guests arriving from multiple directions faced delays simultaneously. Hosts can act now by preparing a clear, templated guest communication for flight disruption scenarios, identifying nearby accommodation options for stranded guests, and keeping a current list of official information sources such as Indonesia's Geological Agency and AirNav Indonesia. Flexible check-in windows and a straightforward rebooking policy can turn a stressful situation into a positive guest experience. Given that Anak Krakatau activity has been escalating since July, this is a good moment to review cancellation terms and ensure they reflect force-majeure realities.
