Indonesia’s Mount Anak Krakatau unleashed a 25-hour continuous eruption starting late September 4, 2026, sending lava fountains and ash plumes up to 50,000 feet high.
The event shut down airports like Jakarta’s Soekarno-Hatta, stranding tens of thousands of passengers, while ash blanketed areas from Banten to Bengkulu, leading to mask advisories.
Activity has eased to typical Strombolian bursts, but Alert Level III remains with a 3-kilometer exclusion zone—no casualties reported.
