Takawangha is a 1449-m-high, young stratovolcano on northern Tanaga Island near the western end of the Andreanof Islands in the Aleutian arc. It is capped by an ice-filled summit caldera.
Due to its remoteness, there are no historical observations of activity, but radiocarbon dates indicate it has probably been active about 500 years ago. In November 2022, seismic unrest was detected under the volcano, suggesting internal magma movements that could be precursor to new activity in the future.

Background

Takawangha lies across a saddle from historically active Tanaga volcano to the west; older, deeply eroded volcanoes lie adjacent to Takawangha on 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 of the volcano. No historical eruptions are known from Takawangha, although radiocarbon dating indicates explosive eruptions have occurred within the past several hundred years.

Takawangha (United States) - Smithsonian / USGS Weekly Volcanic Activity Report for 12 July-18 July 2023

AVO reported that earthquake activity near Takawangha had decreased in both rate and magnitude. The rate of earthquakes had been about three events per day during the previous three weeks, much lower than the 150 events per day recorded during the peak of the swarm in mid-March. Recent satellite images did not indicate any deformation on the island and no other signs of volcanic unrest had been detected. ... Read all
