Volcán Yucamane lies at the south end of a group of three volcanoes; both it and Cerro Caliente to the north display evidence of postglacial lava flows, which overlie thick moraines. The andesitic Yucamane volcano has a youthful, well-preserved summit crater. Late-Pleistocene and Holocene eruptions have produced airfall deposits, pyroclastic flows and surges, and block-and-ash flows produced by growth and collapse of lava domes. The most recent plinian eruption took place from Yucamane about 3300 radiocarbon years ago. A single historical eruption of uncertain character was reported in 1787 (Volcanological Society of Japan, 1971). Historical eruptions attributed to the more dissected Tutupaca volcano during the 18th-20th centuries (Catalog of Active Volcanoes of the World), were considered by de Silva and Francis (1990) to have more likely originated from Yucamane volcano.

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.

|Volcán Yucamane (center) lies at the south end of a group of three volcanoes between the Río Callazas (left-center) and Río de Calientes (right-center). Laguna de Vilacota (upper right) lies east of the volcano. Both Yucamane and Cerro Caliente, the edifice immediately to the north, display evidence of postglacial lava flows. The andesitic Yucamane volcano has a youthful, well-preserved summit crater, and the volcano may have had historical eruptions.

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.
