The Center for Volcanology and Geological Hazard Mitigation (PVMBG) reported a significant increase in volcanic activity at Mount Anak Krakatau on Wednesday (8/7/2026). The volcano, located in the waters of the Sunda Strait, was recorded erupting six times in less than 10 hours.
The series of eruptions began in the early hours at 00:11 WIB, recorded by seismographs with a maximum amplitude of 24 millimeters. Activity continued throughout the morning until 09:54 WIB, with varying eruption intensities. The volcanic ash column reached an average height between 100 and 250 meters above the summit, with the ash dispersion primarily directed toward the north to northwest.
An officer at the Anak Krakatau Volcano Observation Post (PGA), Deny Mardiono, confirmed that each eruption had distinct seismic characteristics, with a maximum amplitude recorded at 49 millimeters during the 09:35 WIB eruption. Despite the fairly intense frequency of eruptions, volcanological authorities have so far maintained the mountain's status at Level III or Alert.
As a preventive measure, PVMBG has urged the public, fishermen, and tourists to refrain from approaching the active crater. A safety zone has been established within a 3-kilometer radius of the eruption center to mitigate the risk of ejected volcanic material or subsequent hazards.
The public is asked to remain calm yet vigilant, and to regularly monitor updated information through official PVMBG channels. Authorities continue to conduct intensive monitoring to track fluctuations in the activity of the volcano situated in the vital Sunda Strait corridor.
