The Geological Agency of the Ministry of Energy and Mineral Resources (KESDM) set the status of Mount Soputan in Southeast Minahasa and Mount Lokon in Tomohon, North Sulawesi, to Level II (Alert/Waspada) as of Monday (13/7/2026). This status designation was made based on intensive monitoring of the volcanic activity of both mountains.
Mount Soputan observer, Jeheskiel Harto Proklami Montolalu, reported that visual conditions of the mountain were clear, with white crater smoke observed rising to a height of 10 meters. Seismic data recorded activity indicating the need for caution among communities around the area.
On the other hand, Mount Lokon observer, Armando Manguleh, stated that volcanic activity on the mountain remains fluctuant. Based on instrumental monitoring, shallow volcanic, local tectonic, and distant tectonic activities were recorded, requiring continuous monitoring by authorities.
To avoid unwanted risks, relevant authorities strictly prohibit the public and tourists from engaging in any activities within a 1.5-kilometer radius of the craters of both mountains. This advisory includes a ban on hiking and activities within the designated danger zone.
Local residents are also requested to remain calm yet vigilant, particularly regarding the potential for ash fall in the event of an eruption. Residents are advised to prepare masks and eye protection, as well as to increase alertness against potential cold lava floods along river basins originating from the peak, especially during periods of heavy rainfall.
