A volcanic eruption from Anak Krakatau has left some 270,000 passengers stranded across Indonesia, grounding more than 2,000 flights and forcing four airports, including Jakarta's Soekarno-Hatta International, to extend closures until Monday evening as volcanic ash continues to spread.

Anak Krakatau, located approximately 150km from Jakarta, began erupting late Friday, producing lava fountains and sending volcanic ash into the capital and Lampung province. The volcano remained seismically active over the weekend, with the most recent eruption occurring at 20:23 local time on Sunday, according to Indonesia's geological agency.

By Monday, Jakarta's Soekarno-Hatta International and three other airports suspended operations until 18:00 local time after ash was detected in nearby airspace. Schools in the region moved classes online, and some shipping operations were also disrupted.

At the departure halls of Soekarno-Hatta, snaking queues formed as stranded passengers sought refunds and updates. Finna, a 46-year-old stranded in Malang, East Java, described the chaos: "It was very crowded because passengers from the morning flights had piled up, while those scheduled for later departures still didn't know what would happen." She eventually spent the night on two intercity trains to reach Jakarta.

Jo Shaw, visiting with her conservation charity Save the Rhino International, said her team had cancelled plans to camp at Java's Ujung Kulon National Park after authorities raised alert levels. "Being stranded in an airport hotel is a relatively minor inconvenience," she said, adding that she was more concerned about teams working on the ground with rhinos under the environmental conditions.

Amir Hamzah, a Malaysian newlywed stranded in Bali, told Bernama that his next flight to Kuala Lumpur was not until 11 September. "We thought we would just sleep at the airport for a few hours and then take the morning flight home. We never thought we would end up being stuck here for days."

On Monday, Indonesia's Geological Agency warned that "the probability of further eruptions in the coming periods remains high." Volcanic ash reached as high as 6,000m on the Java side and 15,000m on the Sumatra side, according to the BMKG meteorological agency.

Transport Minister Dudy Purwagandhi said in relation to the temporary closures: "We cannot ascertain when this will end due to the dynamic weather."

Analysis

Why This Matters

Nearly 270,000 travelers are stranded, with flights disrupted across Indonesia, affecting tourism, business travel, and cargo shipments.
The extended airport closures highlight the vulnerability of air travel to volcanic ash, which can damage aircraft engines and reduce visibility.
Continued seismic activity raises the risk of further eruptions, prolonging disruption and potentially threatening nearby communities.

Background

Anak Krakatau ("Child of Krakatau") is a volcanic island in the Sunda Strait between Java and Sumatra. It emerged in the 1920s from the caldera left by the catastrophic 1883 Krakatau eruption, one of the deadliest volcanic events in history. The volcano has been intermittently active since, with notable eruptions in 2018 that triggered a tsunami. The current eruption began late Friday, sending ash clouds up to 15,000m and affecting airspace over major airports.

Key Perspectives

Stranded passengers: Travelers face lengthy delays, cancelled plans, and financial strain as they scramble for alternative transport or wait days for flights. Some have resorted to trains, while others remain uncertain about when they can leave. Indonesian authorities: Airports and the transport ministry prioritize safety, extending closures to avoid ash hazards. The geological agency monitors seismic activity and warns of high eruption probability. Conservation and local communities: Groups working near the volcano express concern over environmental conditions and the impact on wildlife. Schools have moved online, and shipping disruptions add to economic strain.

What to Watch

Ash dispersal and weather patterns: Dynamic weather will determine how quickly airports can reopen and how far ash spreads.
Further eruptions: The geological agency warns of high probability of additional eruptions in the coming days.
Airline response and passenger compensation: Airlines face logistical challenges in rebooking or refunding tickets for hundreds of thousands of passengers.
