The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that explosive activity continued at Dukono during 22-28 January. Emissions were observed daily; white-and-gray emissions rose as high as 800 m above the summit. Seismicity included 189-340 daily explosion events and episodes of continuous tremor. The Alert Level remained at Level 2 (on a scale of 1 to 4), and the public was warned to stay outside of the 4-km exclusion zone.
Geological Summary. The Dukono complex in northern Halmahera is on an edifice with a broad, low profile containing multiple peaks and overlapping craters. Almost 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 Gunung Mamuya cone, 10 km NE. Malupang Wariang, 1 km SW of the summit crater complex, contains a 700 x 570 m crater that has also had reported eruptions.
