Volcanic activity of Mount Anak Krakatau in the waters of the Sunda Strait has shown an increase again. On Friday (10/7/2026) afternoon at 16:42 WIB, the volcano was observed undergoing an eruption that spewed volcanic ash material into the air.
The Center for Volcanology and Geological Hazard Mitigation (PVMBG) recorded the spewed ash column reaching a height of about 250 meters from the peak, or equivalent to 407 meters above sea level. The ash material was observed to be thick black in color, moving with the wind towards the north, northeast, and northwest.
In addition to visual observation, this eruptive activity was clearly recorded on a seismogram with a maximum amplitude of 55.2 millimeters. The tremors lasted briefly, for approximately 33 seconds.
To date, authorities maintain Mount Anak Krakatau's status at Level III or Alert. As an anticipatory measure against potential hazards, the public, tourists, and fishermen are strictly prohibited from conducting activities within a 3-kilometer radius of the active crater area.
PVMBG continues to urge residents around coastal areas to remain calm and constantly monitor information updates through official government channels. Compliance with the safe distance recommendation is highly emphasized to minimize safety risks from the still-fluctuating eruptive activity.
