A pilot report from a Qantas flight on the morning of 25 September described a plume to 6 km altitude that was drifting ESE. Visible satellite imagery failed to detect volcanic ash, but weather clouds in the SE sector were identified with infrared imagery.
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.
