The long-term eruption at Dukono has been characterized by frequent ash explosions through at least March 2018 (BGVN 43:04). The current report shows that this pattern continued through at least September 2018. The data below were provided by the Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG), also known as the Center for Volcanology and Geological Hazard Mitigation (CVGHM), and the Darwin Volcanic Ash Advisory Centre (VAAC).

Between April and September 2018 there were about five reports per month about ash plumes. Altitudes generally ranged from 1.4-2.1 km, although 3 km was reported during 2-8 May and 3.4 km was reported during 25-31 July (table 18).

Month Plume Altitude (km) Notable Plume Drift
Apr 2018 1.5-2.1 --
May 2018 1.5-3 Ash plumes drifted as far as 225 km NW on 28 May
Jun 2018 1.4-2.1 --
Jul 2018 1.8-3.4 --
Aug 2018 1.8-2.4 --
Sep 2018 1.8-2.1 --

No thermal anomalies at Dukono, based on MODIS satellite instruments analyzed using the MODVOLC algorithm, were detected during the reporting period. The MIROVA (Middle InfraRed Observation of Volcanic Activity) volcano hotspot detection system, also based on analysis of MODIS data, detected a low-power hotspot in early April (about 2.5 km from the volcano) and a possible low-power hotspot in late August 2018 (about 5 km from the volcano).

Geological Summary. 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, have occurred since 1933. During a major eruption in 1550 CE, a lava flow filled in the strait between Halmahera and the N-flank Gunung Mamuya cone. 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.
