Volcán Huequi is a small, glacier-free lava-dome complex in the center of the Huequi Peninsula in Ancud Bay. The 1318-m-high basaltic-andesite to dacitic volcano consists of a complex of lava domes within an arcuate collapse depression with debris-avalanche deposits extending to the northwest. Explosive eruptions were recorded during the 19th and 20th centuries, initially in 1890 and most recently in about 1920.

The roughly 20-km-wide Huequi Peninsula extends about 40 km into the Gulf of Ancud in southern Chile. Volcán Huequi is a small, glacier-free volcano located just to the right of the center of this NASA International Space Station image (with north to the upper left). A parasitic cone is located on the west side of the 1318-m-high basaltic-andesite volcano, which has an 800-m-wide crater. Explosive eruptions were recorded during the 19th and 20th centuries, initially in 1890 and most recently in about 1920.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
