The Cerros de Guayaques group of N-S-trending rhyodacitic lava domes straddles the Chile-Bolivia border. The 10-km-long chain is located immediately east of the Purico pyroclastic shield. There is some evidence for Holocene activity, and the youngest domes appear to be north of the summit crater of the dome complex (de Silva and Francis, 1991). A well-defined summit crater was the source of the largest lava flows, which traveled 3 km to the SW. There are no records of historical activity from Guayaques volcano.

The Global Volcanism Program is not aware of any Holocene eruptions from Guayaques. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Guayaques 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 irregular 10-km-long N-S-trending chain just left of the center of this Landsat image is Cerros de Guayaques. These rhyodacitic lava domes straddle the Chile-Bolivia border. The 10-km-long chain is located immediately east of the Purico pyroclastic shield, part of which is visible on the left side of the image. A well-defined summit crater was the source of the largest lava flows, which form the lobate flows that extend 3 km to the SW. There are no records of historical activity from Guayaques volcano.

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.
