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 snow-capped Taapaca (Nevados de Putre) volcanic complex rises to the north above rhyodacitic pyroclastic deposits in the Pampa del Muerto. Taapaca volcano rises NE of the town of Putre in northern Chile. Putre is built on top of debris-avalanche deposits from Taapaca, which consists of a dacitic lava-dome complex. The latest stage of activity during the Holocene produced the 5860-m-high summit lava dome complex (center horizon).

|The Taapaca volcanic complex rises to the NE above the town of Putre, just out of view to the left. The elongated volcanic massif consists of an initial andesitic stratovolcano and a long-term dacitic lava-dome complex. The 5860-m-high dome complex on the right horizon is part of the Holocene Putre unit, formed during the latest eruptive stage. The left-hand dome is part of the late-Pleistocene Socapave unit. A pyroclastic apron from Taapaca, including a late-Pleistocene debris-avalanche deposit, forms the foreground.

|The elongated Taapaca massif rises to the SE above the gentle slopes of block-and-ash flow deposits from the volcano. The steeply dipping lava flow on the left horizon caps hydrothermally altered rocks of a Pleistocene stratovolcano of the Taapaca II complex. The dome complex at the center is of part of the dacitic Pleistocene Taapaca III complex, and the light-colored dome at the right is part of the dacitic Pleistocene-to-Holocene Taapaca IV complex.

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.
