Anak Krakatau eruption grounds 200+ flights at Jakarta's main airport
Mount Anak Krakatau erupted in Indonesia's Sunda Strait, sending ash as high as 50,000 feet and forcing Jakarta's Soekarno-Hatta International Airport to suspend operations, affecting more than 200 flights.
Mount Anak Krakatau erupted before dawn on September 6, 2026, sending volcanic ash as high as 50,000 feet into the sky and grounding more than 200 flights at Jakarta's Soekarno-Hatta International Airport. Indonesia's disaster agency told residents in Java and Sumatra to wear masks and limit outdoor activity as ashfall continued. Officials say there is no tsunami risk from this eruption, a distinction that matters given the volcano's 2018 collapse-driven tsunami. The volcano remains at Level III (Siaga) alert with a 3 km exclusion zone enforced around the crater.
