Unboi Island is the largest of the volcanic Islands off the north coast of New Guinea. It is 50 km long and contains Umboi volcano, a mainly basaltic-andesitic complex of several overlapping stratovolcanoes.
The Umboi volcanic complex is cut by a large 13 x 17 km caldera with up to 1 km high walls. The caldera is open to the NE and has 3 young cones containing summit crater lakes: Talo, Soal and Barik. Talo is the largest of these cones and has several thermal areas with hot springs, bubbling mud ponds and fumaroles. Talo also has flank cones.
There are no known eruptions in historic times, but it is believed that the post-caldera cones habve been active within the past few hundred years.

Umboi Island played an important role in providing wood for building sailing canoes used in ancient trade of goods including obsidian.

Raung volcano photos: One of the largest and most active volcanoes in East Java, rarely-visited and relatively unknown Raung became (in)famous during its recent eruption in 2015 when its frequent ash plumes forced the repeated closure of Bali's airport.
