Takawangha

Estratovolcán · United States · 1449 m

Takawangha is seen here looking E from the summit of East Tanaga. It lies across a saddle from historically active Tanaga volcano to the west. The summit has five Holocene craters that produced explosive eruptions and lava flows that reached the lower flanks during the last few thousand years.

Resumen geológico

Takawangha is a youthful volcano with an ice-filled caldera on northern Tanaga Island, near the western end of the Andreanof Islands. It lies across a saddle from historically active Tanaga volcano to the west; older, deeply eroded volcanoes lie adjacent to the east. 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. No historical eruptions are known, although radiocarbon dating indicates explosive eruptions have occurred within the past several hundred years.
