Based on PVMBG observations and satellite data, the Darwin VAAC reported that during 13-17 June ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted in multiple directions.

Eruptive activity at Dukono has continued since 1933. As previously reported, ash explosions were frequently observed, and thermal anomalies were intermittent, from September 2011 through July 2014 (BGVN 39:06). Similar activity has continued through March 2017.

Monitoring is conducted by the Indonesian Center for Volcanology and Geological Hazard (PVMBG, also known as CVGHM) from an observation post 11 km away. The Alert Level has remained at 2 (on a scale of 1-4), with residents and tourists advised to not approach the crater within a radius of 2 km.

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.
