Mount Dukono Erupts Again, Ash Column Reaches 1.3 Kilometers

Mount Dukono in North Halmahera erupted again on Tuesday, June 2, 2026, sending a column of volcanic ash approximately 1.3 kilometers into the sky. The eruption, which occurred at 7:55 AM WIT, was characterized by white to gray ash clouds moving eastward.

According to Bambang Sugiono, an observer at the Mount Dukono Observation Post, the eruption registered a maximum amplitude of 34 millimeters on the seismogram and lasted for 43.67 seconds. This follows a previous eruption on Monday, where the ash column reached about 900 meters above the peak.

Mount Dukono has been exceptionally active this year, with 157 eruptions recorded since January 2026, making it the third most active volcano in Indonesia. The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has maintained the volcano's status at Alert Level II (Waspada).

Authorities have advised the public and hikers to avoid activities within a four-kilometer radius of the Malupang and Warirang craters. Lana Saria, the acting head of the PVMBG, also recommended that residents in the vicinity carry masks to protect their respiratory systems from volcanic ash.
