Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that on 18 December a possible ash plume from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted over 35 km E. On 24 December an ash plume rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted 55 km N.
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.
