Takuan Group

Compound volcano · Papua New Guinea · 2210m

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.

Geological summary

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.
