Jakarta Airport Closed by Volcanic Ash

Indonesia suspended operations at its main international airport outside Jakarta on Sunday, September 6, 2026, after volcanic ash from the eruption of Mount Anak Krakatau drifted into the airspace. The closure of Soekarno-Hatta International Airport disrupted hundreds of flights and affected more than 22,000 passengers, with significant impacts on routes to and from Singapore. The eruption began late on Friday, September 4, with the volcano producing a fountain of lava and booming sounds that could be heard up to 700 kilometers away, according to Indonesia's geology agency. Two additional eruptions were recorded on Sunday. Ash from the volcano was detected in the airspace surrounding the airport, prompting authorities to initially suspend operations from 1:30 a.m. local time on Sunday. The suspension was later extended until 9:30 a.m. local time after tests confirmed the continued spread of volcanic ash in the airport area, the transport ministry said. The disruption affected 209 flights, according to the transportation ministry, with international routes to Singapore, Doha, Sydney, and Kuala Lumpur among those impacted.
