Anak Krakatau Eruption Sends Ash 15 Kilometers High, Disrupts Jakarta Flights

Anak Krakatau, a volcanic island in Indonesia's Sunda Strait, began erupting on the night of September 5, 2026. The volcano has a long history of frequent eruptions since it emerged in 1927, making it one of the region's most closely monitored natural hazards.

As the eruption began, dense ash clouds started rising above the volcano and spreading over the surrounding areas. Initial warnings were issued for people to stay away from the immediate vicinity, as the risk of further explosions and falling ash was high.

By the early hours of September 6, the eruption intensified, with ash plumes reaching as high as 15 kilometers into the atmosphere. This ash drifted toward populated regions, including parts of Java and Sumatra.

Authorities quickly responded by suspending all flights at Jakarta's Soekarno-Hatta International Airport and the airport in Lampung, citing concerns over visibility and aircraft safety. The closure began early in the morning and forced hundreds of travelers to change their plans.

International flights to and from major Asian cities, including Singapore, Kuala Lumpur, Guangzhou, Hong Kong, and Doha, were delayed or canceled as the ash cloud continued to spread. Airlines such as Singapore Airlines were among those affected by the disruptions.

By midday, the suspension of airport operations was extended as the eruption showed no signs of slowing down. The number of affected flights climbed to over 200, causing widespread travel disruption for both domestic and international passengers.

The eruption brought back memories of previous disasters linked to Anak Krakatau, including a deadly tsunami in 2018 that claimed hundreds of lives.

As of now, flights at Jakarta and Lampung airports remain suspended due to ongoing ash emissions from Anak Krakatau. Thousands of passengers have been impacted, and authorities continue to warn residents to avoid the area around the volcano.

The situation is still developing, with officials closely monitoring volcanic activity and air quality. The potential for further eruptions or changes in wind direction could prolong travel disruptions and increase risks to local communities.

Authorities will decide when to reopen airports based on volcanic activity and ash dispersal. Travelers should expect continued delays and monitor official updates.

There is also concern about possible health effects from ash fall and the risk of additional eruptions, so local residents are being urged to follow safety instructions.
