Core Event: Ash Cloud Forces Airport Shutdowns
An eruption of Mount Anak Krakatau sent ash columns up to 20,000 ft (6,000 m) on Java and 50,000 ft (15,000 m) on Sumatra, blanketing Jakarta and surrounding provinces. The ash prompted the closure of eight airports, including Soekarno-Hatta International Airport, on Sept 6. Flight operations were suspended until late-night extensions, affecting hundreds of flights and stranding thousands of passengers.
Background & Context
Anak Krakatau, “child of Krakatau,” emerged in the caldera left by the 1883 eruption that killed more than 36,000 people. The volcano sits in the Pacific “Ring of Fire.” A 2018 eruption triggered a tsunami that killed over 400 people.

Official Statements & Responses
Transport Minister Dudy Purwagandhi emphasized safety inspections before resuming flights and asked passengers for patience. The disaster-mitigation agency BNPB announced a cloud-seeding operation to encourage rain that could wash ash from the atmosphere. The BMKG warned that ash could damage jet engines and reduce visibility, urging the public to wear masks and limit outdoor activity. The Directorate General of Civil Aviation reiterated that safety remained the top priority.
On-the-Ground Reports
Passengers described confusion and frustration. Ersy Laksita Rini, 55, arrived at Soekarno-Hatta only to learn her 8 a.m. flight to Surabaya was cancelled, saying she had received no prior notice. Carlos Zabala, 24, travelling to Spain, blamed airlines for a lack of clear communication.
Conflicting Reports & Gaps
Sources differ on the scale of disruption: Reuters cites 964 flights at Jakarta and over 1,500 nationwide, while SCMP reports nearly 3,000 flights and 340,000 passengers. The Globe and Mail gives 1,558 cancelled flights and 170,000 passengers, whereas ARN News Centre mentions 270,000 passengers and 2,300 flights.
