Volcanic Eruption Disrupts Flights, Stranding 170,000 Passengers in Indonesia

A volcanic eruption in Indonesia has caused widespread disruption to air travel, leaving about 170,000 passengers stranded after authorities temporarily shut eight airports.

Jakarta's Soekarno-Hatta International Airport was among the first facilities affected on Sunday after volcanic ash from Anak Krakatoa was detected in nearby airspace.

Indonesia's Transport Ministry said 1,558 flights had been delayed, with the affected airports expected to remain closed until 9am local time on Monday.

Anak Krakatoa began erupting late on Friday, producing sustained seismic activity, lava fountains and powerful booming noises that were heard across surrounding areas. Authorities reported two additional eruptions early on Sunday.

The disruption has particularly affected flights operating to and from Singapore, while other international services involving destinations including Doha, Sydney and Kuala Lumpur have also been impacted.

Transport Minister Dudy Purwagandhi said the decision to close additional airports followed monitoring that showed volcanic ash moving towards West Java.

He called on airlines to accelerate ticket refunds for passengers whose flights had been cancelled and urged carriers to provide clear and timely updates to travellers with upcoming services.

The minister also warned airlines to help prevent overcrowding at airports by keeping affected passengers informed about cancellations, delays and alternative travel arrangements.

Indonesia's meteorological agency, BMKG, reported that volcanic ash had reached altitudes of about 20,000 feet (6,000 metres) over Java, east of the volcano. On the western side, towards Sumatra, ash was detected at heights of up to 50,000 feet (15,000 metres).

Despite the scale of the eruption, authorities said there was currently no tsunami warning associated with the volcanic activity.

Health Minister Budi Gunadi Sadikin advised people living in areas affected by volcanic ash to remain indoors where possible and wear face masks. Exposure to volcanic ash can cause irritation to the respiratory system, eyes and skin.

Anak Krakatoa, which lies in the Sunda Strait between Java and Sumatra, has a history of dangerous eruptions.

Authorities continue to monitor the volcano and atmospheric conditions as aviation restrictions remain in place.
