Mount Anak Krakatau, located in the waters of the Sunda Strait, has once again shown a significant increase in volcanic activity. Throughout Friday (10/7/2026), a total of five eruptions were recorded, spewing ash material into the atmosphere to varying heights.
According to a report from the Geological Agency of the Ministry of Energy and Mineral Resources, the series of eruptions began at 16:42 WIB and lasted until 21:40 WIB. The highest eruption was recorded during the first explosion, with an ash column reaching 250 meters above the peak, or about 407 meters above sea level. The dispersal of the thick gray to dark black volcanic ash was observed moving north, northeast, and northwest.
Head of the Mount Anak Krakatau Observation Post in Hargo Pancuran Village, Andi Suwardi, explained that the entire series of eruptions was well recorded by seismic instruments. The maximum amplitude ranged from 44.3 to 55.2 millimeters, with eruption durations between 27 and 49 seconds.
Although the eruption frequency has increased in recent days, authorities emphasized that the status of Mount Anak Krakatau remains at Level III (Alert). According to Andi, this status determination is based on a comprehensive evaluation of various parameters, rather than simply counting the daily number of eruptions.
The Geological Agency continues to urge the public, fishermen, and tourists to strictly maintain a safe radius of three kilometers from the active crater. The safety of residents remains the top priority amid the dynamic volcanic activity, which is being closely monitored to anticipate potential further changes in alert status.
