A NOTAM issued from the Ujung Pandang aviation control center on 30 January noted the presence of a volcanic ash cloud from Dukono with both altitude and drift direction unknown. Satellite imagery gave no indication of the presence of volcanic ash, although there was evidence of a low-level smoke plume.
Geologic Background. 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. This complex volcano presents a broad, low profile with multiple summit peaks and overlapping craters. Malupang Wariang, 1 km SW of the summit crater complex, contains a 700 x 570 m crater that has also been active during historical time.
