Overview
The Takuan volcano group in southern Bougainville Island consists of three closely spaced, NW-SE-trending andesitic-dacitic stratovolcanoes. Two of these are relatively uneroded and have probably been active during the Holocene, and a third, extensively eroded volcano is probably Pleistocene in age (Blake and Meizitis, 1967). Along with Loloru volcano, the Takuan volcanoes are post-caldera cones constructed along the rim of the Pleistocene Laluai caldera.
The 2210-m NW-most volcano, Mount Takuan, is the highest of the group and is a lava cone that has fed viscous lavas flows to the south, similar to those at Bagana volcano. The central volcano contains a large lava dome in its breached summit crater; this dome may represent the most recent activity of the Takuan volcano group. Older, but still well-preserved lava flows are found on the flanks of this volcano.

About the Photo
The Takuan Group in southern Bougainville Island, Papua New Guinea, is shown in this Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 12.5 km across). The group contains three edifices along a NW-SE trend, all of which have probable collapse scarps, and erosion on the flanks. The volcano in the center has a lava dome that has formed within the scarp.
