Eight Airports Down, No End in Sight
Volcanic ash from Anak Krakatau has forced the closure of eight Indonesian airports, including the primary gateways serving Jakarta, as of Monday, September 7, 2026. The eruptions began late Friday, and ash has since spread across Jakarta and several neighboring areas. Indonesia's Transport Minister Dudy Purwagandhi confirmed the closures in a Monday statement, noting that the airports serving Jakarta's nearby provinces of Lampung and West Java were also affected. The minister was direct about the uncertainty: reopening could not be confirmed because of what he described as dynamic weather conditions.
The transport ministry estimates that 170,000 people have been affected by flight cancellations, a figure that underscores just how broadly this disruption has rippled across the region.
What the Eruptions Look Like
Anak Krakatau sits in the Sunda Strait, roughly midway between Java and Sumatra. The volcano monitoring agency recorded the most recent eruption on Sunday evening. Ash columns have reached 6,000 meters on the Java-facing side of the volcano and as high as 15,000 meters on the Sumatra side, according to Indonesia's meteorological agency BMKG. Parts of Banten province in Java have also been affected.
The disaster management agency has advised anyone traveling outdoors to wear masks. In Jakarta and Lampung, schools have shifted to remote learning to limit students' exposure to ash fall, as reported by state news agency Antara.
A Volcano With a Long History
Anak Krakatau, whose name translates roughly as "child of Krakatau," emerged from the seafloor about a century ago at the site of its predecessor, the volcano historically known in the West as Krakatoa. That older volcano collapsed catastrophically in 1883 in a series of eruptions that triggered tsunamis and killed more than 36,000 people. Indonesia's position on the Pacific Ring of Fire means volcanic activity and earthquakes are recurring realities for the country.
Why It Matters for Hosts
For independent accommodation operators in Jakarta and the surrounding region, this event is a reminder that volcanic disruption can materialize quickly and last for an unpredictable period. Practical steps worth taking now include reviewing your cancellation and rebooking policies so guests stranded by airport closures have a clear, fair path forward; keeping direct communication channels open so affected guests can reach you without relying on third-party platforms; and stocking basic supplies such as masks in common areas for guests who need to move around the city. Longer term, having a written contingency plan for natural-disaster disruptions, including contacts at local transport offices and a clear refund framework, will help you respond calmly the next time an event like this occurs.
For travelers with upcoming Jakarta itineraries, the priority is monitoring official updates from Indonesian aviation and transport authorities before heading to any airport in the region.
