Based on visual observations, CVGHM reported that during 18-25 June ash plumes from Dukono rose to an altitude of 1.4 km (4,600 ft) a.s.l. The Alert Level remained at 2 (on a scale of 1-4).
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.
