Volcanic activity at Mount Awu in the Sangihe Islands, North Sulawesi, showed fluctuating dynamics during the period of June 23 to 30, 2026. According to an official report from the Ministry of Energy and Mineral Resources (ESDM), a drop in the frequency of shallow volcanic earthquakes was recorded from 18 to 16 events per day.
However, the Geological Agency noted an increase in deep volcanic earthquake activity. Furthermore, the post-effects of a major earthquake in Mindanao, Philippines, in early June continue to trigger a high frequency of distant tectonic earthquakes in the region. Visual observations of the crater have not shown significant changes either, with smoke emissions still limited to inside the crater area.
Acting Head of the Geological Agency, Lana Saria, emphasized that the potential threat of magmatic and phreatic eruptions still needs to be watched closely. The continuous dynamics of magma supply at shallow depths demand vigilance regarding the possibility of a sudden surge in seismic activity or earthquake swarms.
As of now, Mount Awu's alert level is maintained at Level III (Alert). The public and tourists are strictly prohibited from carrying out any activities within a four-kilometer radius of the crater center. Authorities urge residents to remain calm and rely solely on official information from relevant agencies to avoid irresponsible disinformation.
