Mount Anak Krakatau Activity Subsides but Eruption Risk Remains High
Mount Anak Krakatau's surface activity has eased after a 25-hour eruption, but magma movement and the risk of further eruptions remain high.
Mount Anak Krakatau in the Sunda Strait, Indonesia, experienced a series of surface eruptions from September 4 to 6, 2026. After the continuous eruption episode of approximately 25 hours, the volcano's activity shifted to Strombolian eruptions. As of September 11, 2026, the volcano remains at Alert Level III, indicating a high risk of further eruptions.
Lana Saria, Head of the Geological Agency, reported 14 Strombolian eruptions after the continuous episode concluded. While shallow seismic activity shows a downward trend, volcanic earthquakes have increased, indicating ongoing magma movement. The public is advised to stay within a three-kilometer exclusion zone around the active crater, avoid ashfall areas, and adhere to official government information.
