The last reported activity at Dukono consisted of a plume that reached 6 km altitude on 25 September 1995 (BGVN 20:10). Post-May 2000 MODIS data suggested a significant event during 26 August-7 September 2002. During that period, anomalies rose well above alert detection threshold, triggering 10 thermal alerts. All of the alert pixels were located within a 1-km radius.

Geological Summary. Reports from this remote volcano in northernmost Halmahera are rare, but Dukono has been one of Indonesia's most active volcanoes. More-or-less continuous explosive eruptions, sometimes accompanied by lava flows, have occurred since 1933. During a major eruption in 1550 CE, a lava flow filled in the strait between Halmahera and the N-flank Gunung Mamuya cone. This complex volcano presents a broad, low profile with multiple summit peaks and overlapping craters. Malupang Wariang, 1 km SW of the summit crater complex, contains a 700 x 570 m crater that has also been active during historical time.
