Dukono
Indonesia
1.6992°N, 127.8783°E; summit elev. 1273 m
All times are local (unless otherwise noted)
Based on visual observations, the Center of Volcanology and Geological Hazard Mitigation (CVGHM) reported that during the week of 18-25 June 2007 white-gray ash rose to 50-250 m above the summit. The hazard status of the volcano remained on level 2 (on a scale of 1-4).
No significant change of seismicity was noted with respect to previous weeks, and no thermal anomalies were measured during that week by the MODIS/MODVOLC satellite team (table 6). Subsequently, a sequence of thermal anomalies were measured by satellite between 10 August and 27 October 2007.

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.
