5 November-11 November 2003

During this week repeated aviation messages mentioned Dukono ash plumes of variable density. Some of these messages are summarized as follows.

A 5 November aviation message (Volcanic Ash Advisory) noted a faint ash plume to ~2.4 km a.s.l. and extending 220 km NE of the summit based on satellite imagery (GOES 9, 5 November, 0413 UTC). Another 5 November satellite image (visual data from NOAA-15) analyzed by the U.S. Air Force reported a "very pronounced ash plume" at 2137 UTC.

A 7 November Air Force message described a faint plume stemming from ash and steam eruptions to ~3 km a.s.l. The plume remained visible for ~60 km toward the E where it blew into thicker cirrus clouds thwarting detection.

An 11 November Air Force message described ash and steam to ~3 km a.s.l. moving ESE at 18-28 km/hour. At 0521 UTC the plume extended 120 km ESE of the summit. This observation was based on GOES-9 imagery. Similar reports noted shorter plumes later that day.

29 October-4 November 2003

According to DVGHM, ash explosions at Dukono during October produced low-level plumes. Ash fell around the Tobelo area ~15 km E of the volcano. Dukono was at Alert Level 2 (on a scale of 1-4).

30 July-5 August 2003

During 9-14 July, ash explosions at Dukono produced ash plumes to heights of 800-900 m above the volcano. Ash fell around the towns of Mamuya and Galela. During 15-23 July ash plumes rose to low levels, with a plume reaching ~1 km above the volcano on 22 July. According to the Darwin VAAC, ash was visible on satellite imagery on 31 July and 2 and 3 August, with the highest cloud reaching ~2 km above the volcano.

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, occurred from 1933 until at least the mid-1990s, when routine observations were curtailed. During a major eruption in 1550, a lava flow filled in the strait between Halmahera and the north-flank cone of Gunung Mamuya. Dukono is a complex volcano presenting a broad, low profile with multiple summit peaks and overlapping craters. Malupang Wariang, 1 km SW of Dukono's summit crater complex, contains a 700 x 570 m crater that has also been active during historical time.
