Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Karkar
An ash plume rises above the summit of Karkar volcano in 1979. There are two nested summit calderas at the summit of the forested volcano resulting in a broad, low profile. The 5.5-km-wide outer caldera was formed during one or more eruptions, the last of which occurred 9,000 years ago. The 3.2-km-wide inner caldera was formed sometime between 1,500 and 800 years ago. Most historical eruptions, like this one in 1979, have originated from Bagiai cone within the 300-m-deep inner caldera. Photo by Wally Johnson, 1979 (Australia Bureau of Mineral Resources).

Karkar is a 19 x 25 km forest-covered island that is truncated by two nested summit calderas. The 5.5 km outer caldera was formed during one or more eruptions, the last of which occurred 9,000 years ago. The steep-walled 300-m-deep, 3.2 km diameter, inner caldera was formed sometime between 1,500 and 800 years ago. Cones are present on the N and S flanks of this basaltic-to-andesitic volcano; a linear array of small cones extends from the northern rim of the outer caldera nearly to the coast. Recorded eruptions date back to 1643 from Bagiai, a pyroclastic cone constructed within the inner caldera, the floor of which is covered by young, mostly unvegetated andesitic lava flows.
