New Islands Appear After Indonesia's Anak Krakatau Volcano Erupts
Indonesia’s Geological Agency says the eruptions added nearly 33 hectares and may have opened a new northwest-southeast vent line.
On Friday, October 2, 2026, Indonesia's Geological Agency reported two new islands emerged near Mount Anak Krakatau following a 25-hour eruption in early September, potentially the first in nearly a century within the caldera.
Anak Krakatau itself formed within the caldera left by the catastrophic 1883 Krakatau eruption, which killed more than 36,000 people. For 96 years, the site's history has been the making and remaking of this volcanic landmass.
The formations sit about 760m northwest and 495m southeast of the volcano, yet the PVMBG Centre for Volcanology and Geological Hazard Mitigation cannot confirm whether they are new eruptive vents or accumulated volcanic material.
While searching for journalists missing since the September eruption, a tourism activist accidentally spotted the northwestern island via drone footage. Officials continue analyzing Sentinel satellite imagery as the search for the presumed dead proceeds.
Whether these features survive depends on tides and erosion, as Anak Krakatau took multiple attempts to become permanently established before 1930. Indonesia sits on the Pacific Ring of Fire, where high volcanic and seismic activity continues.
Indonesia's Bureau of Geology confirmed the discovery of two new islands that appeared off the coast of the volcano “Anak Karaka” after 25 consecutive hours of eruptions in early September.
