This chain of andesitic-dacitic volcanoes along the Chile-Bolivia border contains at least 10 postglacial centers and stretches from Escalante volcano on the north to Sairecábur volcano on the south. Nomenclature reflecting local usage results in conflicting names applied to these features on Chilean and Bolivian topographic maps. The highest peak, Sairecábur, is located on the northern margin of a 4.5-km-wide caldera. Postglacial activity began south of the summit, but most recently produced a pristine lava flow to the NW. An active sulfur mine is located north of the volcano. Escalante, slightly older than Sairecábur, has a crater lake at its summit and youthful lava flows on its flanks, and other eruptive centers have also produced Holocene lava flows. Curinquinca volcano of Pleistocene-Holocene age lies at the NE end of the complex and Cerro Colorado volcano at the NW end.
The Global Volcanism Program is not aware of any Holocene eruptions from Sairecabur. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Sairecabur 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.

|An aerial photo highlights the volcanic cones and youthful lava flows of the Sairecabur volcanic complex. This chain of volcanoes along the Chile-Bolivia border contains at least 10 postglacial centers and stretches from Escalante volcano on the north to Sairecabur volcano on the south. The highest peak, Sairecabur (lower right), is located on the northern margin of a 4.5-km-wide caldera, whose rim is visible at the bottom center. A pristine lava flow extending to the NW (lower right-center) is the most recent from Sairecabur.

|The N-S-trending chain of andesitic-dacitic volcanoes along the Chile-Bolivia border just left of the center of this Landsat image is the Sairecábur-Escalante volcanic massif. Snow-covered areas are blue in this image of the chain, which contains at least 10 postglacial centers. A massive lava flow extends to the west, and a youthful flow traveled SE from Curinquinca volcano at the NE side of the chain. Laguna Verde is the left-hand lake at the bottom, NE of dark-colored Licancabur volcano; Juriques volcano to its right has a pronounced summit crater.

|The western side of the Sairecábur volcanic complex is seen with thick, blocky lava flows in the foreground. This chain of andesitic-dacitic volcanoes along the Chile-Bolivia border contains at least 10 postglacial centers and stretches from Escalante volcano on the north to Sairecábur volcano on the south. The highest peak, Sairecábur, is located on the northern margin of a 4.5-km-wide caldera. An active sulfur mine is located north of the volcano. Escalante has a crater lake at its summit and youthful lava flows on its flanks.

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.
