Four Eruptions Within Hours: Current Status of Mount Anak Krakatau Today
Mount Anak Krakatau erupted again on Tuesday, 8 September 2026. By midday, the volcano located in the Sunda Strait had recorded as many as four eruptions.
The first eruption occurred at 05:08 WIB, followed by activity at 05:34 WIB and 07:49 WIB. The fourth and most recent eruption was recorded at 11:34 WIB, lasting 17 seconds.
The activity was recorded by a seismograph with a maximum amplitude of 50 mm. Meanwhile, the height of the latest eruption column could not be observed.
Current Status of Mount Anak Krakatau
Amid the series of eruptions, Mount Anak Krakatau’s status today remains at Level III, or Siaga (Alert).
The Geological Agency, through information posted on its official X account, confirmed that this status remains in effect. The public is also asked to heed safety recommendations established on the basis of volcanic activity monitoring results.
“Mount Anak Krakatau currently remains at Level III (SIAGA) with a recommended exclusion distance of 3 km from the centre of activity, which means the eruption potential is still high.”
Under this status, residents and tourists are asked not to approach the centre of Mount Anak Krakatau’s activity within a 3-kilometre radius.
The Geological Agency explained that the volcano’s activity continues to be monitored by the Centre for Volcanology and Geological Hazard Mitigation (PVMBG). Monitoring is carried out using both visual and instrumental observations.
“Mount Anak Krakatau’s activity is continuously monitored visually and instrumentally by PVMBG. An increase in activity is not determined by a single eruption or video, but by various monitoring parameters.”
What Does Level III or Siaga Status Mean?
According to the BPBD website, Level III or Siaga is one of the tiers in the volcanic activity warning system. At this level, volcanic activity has shown an increasingly evident increase based on visual and instrumental observations.
According to the definition of Level III, the condition may take the form of an increasingly evident increase in activity, or an eruption that threatens areas surrounding the eruption centre.
However, Siaga status does not mean that all areas around the volcano are in a dangerous condition. The threat to residents and settlement areas still depends on the characteristics of each volcano as well as the type and development of the activity occurring.
