Broad Takawangha volcano (left), seen here from the east, is a 1449-m-high, youthful stratovolcano on northern Tanaga island with an ice-filled caldera. Numerous small post-caldera tephra cones are located within the caldera, as well as on its rim and flanks. The youngest cones are some of those in the caldera. No historical eruptions are known from Takawangha, in contrast to sharp-peaked Tanaga volcano (right), which occupies the NW tip of Tanaga Island.

The broad Takawangha volcano is seen looking east from the summit of East Tanaga. The 1449-m-high, youthful volcano lies across a saddle from historically active Tanaga volcano to the west. The summit of the dominantly basaltic to basaltic-andesite volcano is largely ice covered, with the exception of five Holocene craters that during the last few thousand years produced explosive eruptions and lava flows that reached the lower flanks of the volcano.
