Volcán Huequi

Huequi

Lava dome · Chile · 1318m

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.

Geological summary

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