An eruption of Indonesia's Anak Krakatau volcano caused widespread travel disruption on September 6, forcing eight airports to suspend flight operations.\n\nIndonesia's transportation ministry said more than 1,500 flights and approximately 170,000 passengers were affected across the eight airports. Jakarta's Soekarno-Hatta International Airport accounted for 964 affected flights.\n\n## Ash affects travel and daily activities\n\nVolcanic ash was detected near the Jakarta airport after Anak Krakatau began erupting late Friday.\n\nSeveral airlines cancelled flights, while authorities identified alternative airports that operators could use when possible. School activities and fishing were also disrupted in affected locations.\n\nResidents exposed to ash were advised to wear masks and eye protection, reduce outdoor activity, cover water sources and exercise caution while driving.\n\n## No imminent tsunami threat reported\n\nIndonesian disaster authorities said there was no imminent tsunami threat from the eruption.\n\nFerries continued operating in the Sunda Strait, but vessels were advised to remain at least three kilometres from the crater and stay alert for volcanic hazards.\n\nPassengers with Indonesia travel plans should verify their flight directly with their airline before proceeding to the airport.
