The Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported an increase in the intensity of volcanic activity at Mount Anak Krakatau, located in the Sunda Strait. From July 2, 2026, until late last week, monitoring instruments recorded at least 18 eruption events.
An officer at the Anak Krakatau Volcano Observation Post, Rio Bonik Situmorang, stated that although activity has been recorded as quite high in recent days, the volcano's status so far remains set at Level III or Alert. To date, the PVMBG continues to closely observe the frequently changing seismic fluctuations.
According to Rio, the last eruption detected by the monitoring equipment occurred on Saturday night, precisely at 23:34 WIB. Visual observations of the volcano from the Pasauran Observation Post in Serang Regency were temporarily obstructed due to thick fog, so monitoring currently relies more on volcanic instrument data operating 24 hours a day.
As a precautionary measure against potential hazards, PVMBG strictly enforces the safe zone recommendation. The public, tourists, and mariners are strictly prohibited from conducting activities or approaching within a three-kilometer radius of the active crater.
Local residents are urged to remain calm and not to be easily influenced by rumors that do not originate from official authorities. The PVMBG is committed to continuously updating information on the development of magma activity to determine appropriate mitigation policies and ensure the safety of residents around the Sunda Strait.
