Based on analyses of satellite imagery, VONAs issued by the Dukono Volcano Observatory, and model data, the Darwin VAAC reported that during 7-13 December ash plumes from Dukono rose as high as 3 km (10,000 ft) a.s.l. and drifted as far as 305 km NE, E, and SE.

Geological Summary. The Dukono complex in northern Halmahera is on an edifice with a broad, low profile containing multiple peaks and overlapping craters. Almost 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 Gunung Mamuya cone, 10 km NE. Malupang Wariang, 1 km SW of the summit crater complex, contains a 700 x 570 m crater that has also had reported eruptions.
