The Global Volcanism Program is not aware of any Holocene eruptions from Chagulak. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Chagulak page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

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.
