The 1142-m-high summit of erosionally modified Chagulak volcano rises above a sea of clouds. The unstudied, poorly known volcano forms a small 3-km-wide island NE of Amukta volcano. The two volcanoes coalesce at depth although they are separated by 7 km of ocean. No historical eruptions have been recorded from Chagulak volcano, and its age is not precisely known.

The ruggedly dissected eastern side of the Chagulak volcano rises to 1142 m above a sea of clouds. Chagulak is the summit of a small, unstudied stratovolcano NE of Amukta, the flat-topped volcano in the left distance. The two volcanoes coalesce at depth although they are separated by 7 km of ocean. No historical eruptions have been recorded from Chagulak volcano, and its age is not precisely known.

The ruggedly dissected eastern side of Chagulak volcano rises to 1142 m above the sea surface as a thin cloud bank hovers around the base of the 3-km-wide island. Chagulak is the summit of a small, unstudied stratovolcano NE of Amukta volcano. No historical eruptions have been recorded from Chagulak volcano, and its age is not precisely known.
