Mount Anak Krakatau, located in the waters of the Sunda Strait, has once again shown a significant increase in volcanic activity. Based on the monitoring report for Tuesday afternoon (7/7/2026), the volcano's crater was observed emitting thick plumes of black smoke accompanied by fairly intense seismic activity.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) confirmed that although the visible smoke reached heights of 10 to 200 meters above the peak, the volcano's activity status remains at Level III or Alert (Siaga). This phenomenon is accompanied by weather conditions around the location monitored as sunny to cloudy, with air temperatures ranging between 29 and 31 degrees Celsius.
Technical data from PVMBG recorded a series of seismic activities during the observation period, including nine emission earthquakes and 12 harmonic tremor earthquakes of varying durations. In addition, officers also recorded one hybrid or multi-phase earthquake event, indicating magma movement beneath the crater surface.
The public and tourists are advised to remain vigilant regarding the development of Mount Anak Krakatau's geological conditions. Authorities continue to conduct strict surveillance and provide periodic warnings to mitigate potential risks that may arise from fluctuations in the volcano's activity.
