Indonesia faced widespread travel disruption Monday after renewed eruptions from Mount Anak Krakatau sent volcanic ash across parts of Java and Sumatra, forcing the temporary closure of eight airports and affecting thousands of passengers.
The volcano, located in the Sunda Strait between Java and Sumatra, began erupting late Friday and continued producing ash and lava activity over the weekend. Authorities said ash clouds reached altitudes of up to 50,000 feet on the Sumatra side, creating a serious hazard for aircraft engines and flight operations.
Indonesia’s Transportation Ministry said eight airports remained affected, including Soekarno-Hatta International Airport serving Jakarta. The closures were extended as officials monitored changing ash conditions and assessed aviation safety. More than 1,500 flights were delayed or canceled, affecting roughly 170,000 passengers across the country.
Airlines have also canceled and rescheduled services. Singapore Airlines announced cancellations on several flights between Singapore and Jakarta, while other carriers have issued travel advisories and adjusted schedules as ash continues to move through regional airspace.
Authorities have urged passengers to check directly with airlines and airports before traveling, warning that operations could change rapidly depending on volcanic activity and wind conditions.
The eruption has also disrupted daily life in affected communities. Schools in Jakarta and parts of Lampung have shifted classes online, while residents have been advised to wear masks and limit outdoor exposure because volcanic ash can irritate the eyes and respiratory system.
Officials continue to monitor Anak Krakatau closely. Indonesia’s disaster authorities have said there is currently no immediate tsunami threat, but the volcano remains under heightened observation and further eruptions are considered possible.
