Indonesian volcano erupts, leaving 170,000 travelers stranded at airports

A series of eruptions from Indonesia's Anak Krakatau volcano has caused widespread disruption, leading to the closure of eight airports and stranding an estimated 170,000 travelers. The volcanic activity, which intensified with significant bursts on Sunday, September 6, 2026, sent ash plumes soaring up to 50,000 feet into the atmosphere. The ash cloud prompted aviation authorities to suspend operations, deeming the conditions unsafe for air travel.

Among the affected facilities were Jakarta's primary international airport, Soekarno-Hatta, and seven other regional airports. The closures resulted in the cancellation or delay of over 1,500 flights, significantly impacting both domestic and international routes. Passengers faced considerable inconvenience, with many expressing disappointment over the unforeseen travel disruptions.

Indonesian authorities have described this as the strongest phase of Anak Krakatau's recent activity, with the volcano showing increased signs of unrest since early September. While no casualties were reported and evacuation orders were not issued for nearby settlements, residents and visitors were advised to maintain a safe distance from the active crater. The situation remains dynamic as officials continue to monitor volcanic activity and assess the impact on air travel.
