The start is PVMBG's 11:07 pm Western Indonesia Time on Friday 4 September (16:07 UTC); the continuous phase lasted about 25 hours and subsided shortly after midnight on Sunday, so the end is approximate. Eruptions on 8 and 9 September are described in the text.[1]Anak Krakatau, the volcano in the Sunda Strait between Java and Sumatra, erupted continuously for about 25 hours from 11:07 pm local time on Friday 4 September 2026, subsiding shortly after midnight on Sunday, according to PVMBG, Indonesia's volcanology agency, as reported by The Star. It then erupted three times on Tuesday 8 September and again at 12:47 am on Wednesday 9 September, for 28 seconds; BMKG's analysis of Himawari-9 satellite imagery showed ash up to 7,000 feet (about 2,134 m) drifting northwest over part of Lampung Bay. The volcano is at Level III of Indonesia's four-level scale, and authorities warned that the potential for more eruptions remains high; the report says recent eruptions disrupted air travel across parts of western Indonesia. The NASA satellite pictures from 4, 5 and 6 September show the lead-up, a long brown ash plume streaming west from the volcano on the 5th, and the haze that remained afterwards.
