After Collapse, It Grows Again

Activity increased again in April 2022. The status of Anak Krakatau was raised from Level II or Alert to Level III or Alert. The public, fishermen and tourists are asked not to approach the crater within a five kilometer radius.

The mountain again showed its glow at night.

In June 2023, Anak Krakatau ejected a column of ash up to around 3,000 meters above the peak. The eruption occurred several times again in November and December of the same year.

Even though it is active, not every eruption means a tsunami will occur. PVMBG continues to differentiate direct threats from craters from possible dangers resulting from changes or collapse of the mountain body.

That's an important lesson after 2018. Caution is not the same as panic. The public needs information quickly, but they also need to understand the type of danger they are facing.

Year after year passed. Anak Krakatau's body slowly re-forms. Vegetation begins to find a place in the quieter parts of the island. Officers continued to monitor him from both sides of the Sunda Strait.

Then, entering mid-2026, activity will increase again.

One night in early September, rumbling and booming sounds crossed the Sunda Strait. The vibrations were felt in places far from the crater. Ash rose high and moved with the wind.

Anak Krakatau reminds us again that its growth is not finished.
