The Geological Agency has officially raised the activity status of Mount Anak Krakatau from Level II (Caution) to Level III (Alert). This decision was made after a series of intensive monitoring sessions showed a significant escalation in volcanic activity at the volcano.
Acting Head of the Geological Agency, Lana Saria, explained that the status upgrade was based on accurate visual and instrumental data. Observations showed an increase in the frequency of volcanic earthquakes as well as deformation of the volcano's body, which are strong indicators of magma supply moving towards the shallow surface.
In addition, tiltmeter monitoring devices at the observation station recorded a trend of inflation or swelling of the volcano's body. This phenomenon indicates a high accumulation of volcanic pressure inside Mount Anak Krakatau.
In response to these developments, the Geological Agency issued a recommendation for a no-activity zone within a 5-kilometer radius of the active crater. This ban applies to the general public, fishermen, and tourists to minimize the risk of eruption hazards and the ejection of incandescent material that could occur at any time.
Relevant authorities have now strengthened coordination with local governments to optimize disaster mitigation measures. Residents along the coast of the Sunda Strait are urged to remain calm but vigilant, and are expected to always monitor official information from volcanology officers and local government directives.
Monitoring of Mount Anak Krakatau is now conducted 24 hours a day. The seismic network and deformation monitoring systems continue to be optimized to ensure that any changes in volcanic activity can be detected earlier for the safety of residents in the surrounding area.
