The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that the eruption at Dukono was ongoing during 20-26 November. Daily gray-and-white ash plumes that were sometimes dense generally rose as high as 3 km above the summit and drifted NW and W. According to a news report an ash plume that rose 1 km above the summit and drifted NW at 0606 on 25 November contained lightning and produced audible rumbling. PVMBG noted that ash plumes rose as high as 4.6 km above the summit and drifted NW on 26 November. The Alert Level remained at Level 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.

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.
