  "account": "The Indonesian Geological Agency has stated that the direction and intensity of ash dispersion from Mount Anak Krakatau's ongoing eruptions, which began last Friday, depend on wind conditions. This ash has already reached parts of western Java, including Jakarta, as well as regions in Lampung and Bengkulu. The distribution of the ash is monitored using data from VONA, Magma Indonesia, VAAC Darwin, and satellite imagery from BMKG’s Himawari-9, with the agency's Head Lana Saria explaining the relationship between wind direction and ash dispersion at an online press conference on September 6, 2026.\n\nSaria emphasized that the height of the eruption column, the duration of the eruption, and the amount of material ejected by Mount Anak Krakatau significantly impact the path of the ash. Consequently, the direction of ash dispersion can change rapidly and needs to be updated based on current meteorological conditions. If the eruption column is higher or the eruption lasts longer, the potential impact area could expand, posing risks to flight paths and populated areas.\n\nLana noted that the Center for Volcanology and Geological Hazard Mitigation (PVMBG) has communicated information about the eruptions to relevant authorities, coordinating this through the Volcano Observatory Notice for Aviation (VONA) mechanism. This information assists aviation authorities and meteorological agencies in ensuring flight safety. The Geological Agency continues to evaluate the activity of Mount Anak Krakatau based on all monitoring data, as the increased volcanic activity since July 2, 2026, indicates a continuous supply of magma and gas within the volcano.",
