Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that Dukono continued to erupt during 20-26 March. Gray-and-white emissions rose as high as 450 m above the summit. The Alert Level remained at Level 2 (on a scale of 1–4), and the public was warned to remain outside of the 3-km exclusion zone.

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.
