The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has officially raised the status of Mount Anak Krakatau to Level III or Alert (Siaga) as of July 2, 2026. This decision was made following a series of increases in volcanic activity monitored intensively since early June.
Head of the Mount Anak Krakatau Observation Post, Andi Suwardi, explained that this status upgrade was based on a comprehensive analysis of various parameters, ranging from Sentinel satellite detection of sulfur dioxide gas emissions to the emergence of thermal anomalies in the crater in mid-June. These natural signs are early indications of magma movement dynamics at shallow depths.
Seismic data recorded from June 16 to July 2, 2026, logged thousands of earthquake activities, including gust earthquakes, hybrid earthquakes, and continuous tremors. This spike in earthquake frequency indicates significant magma pressure beneath the volcano's surface. Culminating on Thursday, July 2, 2026, the volcano spewed an ash column 200 meters high.
In response to this situation, relevant authorities have enforced a no-activity zone within a three-kilometer radius from the eruption center. The public, fishermen, and tourists are urged to comply with these restrictions to avoid the threat of incandescent material projection or hot clouds that could occur at any time.
Nonetheless, PVMBG has asked residents on the coasts of Lampung and Banten to remain calm and not be influenced by unverified rumors. To date, there has been no indication that the eruption has the potential to trigger a tsunami. Residents are urged to monitor the situation through the official communication channels of the government and related institutions.
