Anak Krakatau Volcano's Ash Cloud Reaches Jakarta

Volcanic ash from the eruption of Mount Anak Krakatau was observed to have reached parts of Jakarta on Sunday, September 6, 2026, according to a statement from the Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG). BMKG identified two main clusters of volcanic ash dispersal based on satellite imagery and monitoring by the Center for Volcanology and Geological Hazard Mitigation (PVMBG). This observation was made on September 6, 2026, at 05:00 AM Western Indonesian Time. The first dispersal cluster, extending from the surface up to an altitude of 20,000 feet (approximately 6,100 meters), was observed moving in a Northeast-South direction. This area is reported to include parts of the Jakarta metropolitan area, Banten province, West Java province, and surrounding waters. The second dispersal cluster reached altitudes of up to 50,000 feet (approximately 15,200 meters) and spread westward. This area encompasses Banten province, Lampung province, Bengkulu province, the southern part of the Sunda Strait, and the Indian Ocean west of Bengkulu, Lampung, and Banten. Anak Krakatau, an active volcano that emerged as a successor to the Krakatoa volcano in 1927, is known for its eruptions impacting surrounding regions. The arrival of volcanic ash in Jakarta raises concerns about air quality and potential disruptions to air travel.
