Volcanic activity of Mount Anak Krakatau in the Sunda Strait has shown a significant increase in intensity over the past week. As a result of a series of consecutive eruptions from July 2 to 5, 2026, the status of the active volcano was officially raised from Level II (Advisory) to Level III (Alert).
Data from the observation post recorded that spews of ash and volcanic material have reached a height of 200 meters from the peak of the crater. This condition is worsened by increased seismic activity, where sensors recorded continuous tremor earthquakes or microtremors with a maximum amplitude of 23 millimeters.
Responding to the status upgrade, a joint team consisting of BPBD, Basarnas, and the South Lampung Fire and Rescue Service (Damkarmat) immediately intensified coordination at the Volcano Observation Post in Hargo Pancuran Village. This step was taken to ensure real-time data monitoring and to prepare emergency evacuation scenarios to protect residents in coastal areas.
The Head of the Mount Anak Krakatau Observation Post, Suwarno, explained that although this series of eruptions is a natural growth phase of the volcano, vigilance remains the top priority. The authorities emphasized a strict ban on fishermen and tourists entering the danger zone within a 3-kilometer radius of the center of the crater.
The Head of South Lampung Damkarmat, Rully Fikriansyah, urged the public to remain calm and not be provoked by invalid information. Tighter supervision continues to be carried out to mitigate the risk of hot material ejections, incandescent rocks, and exposure to toxic gases that can occur at any time.
