Summary

Following a 25-hour eruption of Mount Anak Krakatau in September 2026, two new formations resembling small islands were spotted in satellite images of the water-filled caldera in the Sunda Strait. According to Rita Susilawati of the PVMBG Centre for Volcanology and Geological Hazard Mitigation, one formation is located approximately 760 metres northwest of the volcano, while the other is about 495 metres southwest. Authorities have cautioned that it is too early to determine the nature of these formations or whether they will persist, noting that they could be deposits of volcanic material subject to erosion. The eruption also caused significant ecological changes on Sertung Island and widespread travel disruptions.
