PVMBG advises against any activity in the southeast sector along Besuk Kobokan, up to 13 kilometers from the summit (eruption center). Outside this distance, people should not engage in activities within 500 meters of the riverbank (river edge) along Besuk Kobokan due to the potential for pyroclastic flow and lahar flows extending up to 17 kilometers from the summit.
