Three eruptions at Mount Anak Krakatau prompt 5-km exclusion zone

Three distinct eruptions were recorded at Mount Anak Krakatau on Tuesday, with the first occurring at 6:27 a.m. Western Indonesian Time and the final one at 12:28 p.m. WIB. The Geological Agency, which has maintained an Alert Level III since earlier this month, imposed a strict five-kilometre safety perimeter around the volcano’s summit, prohibiting residents, visitors and climbers from approaching. The ban also extends to the northwest and southeast zones, and a tighter one-kilometre exclusion surrounds the new island that has emerged nearby.

Authorities highlighted hazards such as incandescent rock ejection, heavy ashfall, potential lava flows and secondary eruptions caused by lava meeting seawater or rain. Despite the heightened activity, officials asked people on the Banten and Lampung coasts to stay calm and not spread false tsunami warnings.
