Based on analyses of satellite imagery and wind data, the Darwin VAAC reported that during 30 April-6 May ash plumes from Dukono rose to altitudes of 2.4-3 km (8,000-10,000 ft) a.s.l. The plumes drifted 35-185 km SE, E, SW, and W on 30 April and during 3-6 May but stayed in the vicinity of the volcano on the other days.

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.
