POLICY WIRE — Jakarta, Indonesia — Two new landmasses have appeared in the waters surrounding Mount Anak Krakatau following a powerful volcanic eruption last month, according to officials from Indonesia’s Volcano Monitoring Agency.

The formations were identified through satellite imagery of the Sunda Strait, where the volcano sits between Java and Sumatra. Rita Susilawati, head of the PVMBG Centre for Volcanology and Geological Hazard Mitigation, confirmed the discovery, noting that the islands are still under evaluation for their origin and stability.

The September eruption, which lasted 25 hours, caused widespread ashfall and forced multiple airports to shut down, stranding over 300,000 travelers. While the new islands may resemble the ‘children’ of Anak Krakatau, experts caution that they could be temporary features, much like the earlier landmasses that vanished due to erosion.
