25 Hour Eruption of Mount Anak Krakatau Ends, Status Remains Alert Level III

The seismicity of Mount Anak Krakatau is still high

The end of continuous eruptions does not yet indicate that Mount Anak Krakatau's volcanic activity has completely subsided. Instrumental monitoring on 6 to 7 September 2026 still recorded high levels of seismicity.

During that period, officers noted:

Three earthquake eruptions

Nine earthquake gusts

A total of 93 low frequency earthquakes

A total of 98 hybrid or multiple phase earthquakes

Four continuous tremor earthquakes

One shallow volcanic earthquake

Based on the results of these observations, the possibility of another eruption occurring in the next few periods is still considered high. The Geological Agency also maintains the status of Mount Anak Krakatau at Level III or Alert.

“The main potential dangers are in the form of incandescent rocks and heavy ashfall, as well as the potential for lava flows if the eruption continues again,” explained Lana.

Residents Asked to Beware of Volcanic Ash

The Geological Agency reminds people on the coast of Banten and Lampung to continue to follow official developments regarding the activities of Mount Anak Krakatau.

Residents affected by volcanic ash are advised to reduce activities outside the home. If you have to do outdoor activities, people are asked to wear masks to reduce the risk of respiratory problems due to exposure to ash.

The public is also asked to remain calm and not believe information that cannot be justified, especially news linking the eruption of Mount Anak Krakatau with a potential tsunami.

“Communities in the coastal areas of Banten and Lampung must remain calm and not believe in hoax issues related to eruptions that are linked to a potential tsunami. "Residents are asked to carry out normal activities while continuing to follow local BPBD directions," he said. Lana said.
