š Indonesia kept eight airports closed on 7 September after ash from Anak Krakatau entered airspace around Jakarta and other western Indonesian cities. The volcanoās continuous 25-hour eruption had ended, but moderate intermittent eruptions and ash emissions continued.
At four airports managed by InJourney Airports, about 2,300 disrupted flights affected 268,539 passengers. Soekarno-Hatta and Halim Perdanakusuma were among the airports closed because volcanic ash presents an aviation-safety risk.
š« The disruption also reached schools: authorities allowed remote learning in ash-affected parts of Jakarta, West Java, Banten and Lampung to reduce exposure. No sea-level anomaly had been detected by tsunami gauges around the Sunda Strait during the monitoring update.
Anak Krakatau stands in the Sunda Strait between Java and Sumatra and began forming inside Krakatauās 1883 caldera. Its 2018 flank collapse caused a tsunami that killed at least 430 people, illustrating why officials are monitoring both ash and coastal conditions.
āļø Airport operations remain dependent on ash movement and safety assessments. Indonesiaās weather agency said it was continuing round-the-clock monitoring and issuing aviation warnings as conditions changed.
