Cerro del Azufre is the largest and youngest volcanic center of a 50-km-long, NW-SE-trending chain of Chilean volcanoes just west of the Bolivian border, south of Salar de Ascotán. The northern summit forms the 5846 m high point of the andesitic volcano; an older southern stratovolcano extends SE towards the Pleistocene Cerro Aguilucho volcano. A large group of late-Pleistocene lava flows originating from the northern cone extend toward the northern flanks and partially overlies a debris-avalanche deposit now largely buried by the Salar de Ascotán. The Chanka (Pabellón) dacitic lava-dome complex occupying the lower western flank is pristine-looking, but has been Potassium-Argon dated at 1.5 million years. Two possible Holocene dacitic lava domes that were erupted along a NW-SE line east of the summit ridge mark the most recent effusive activity of the Cerro del Azufre complex, but two youthful-looking craters on the main edifice could be of Holocene age.

The Global Volcanism Program is not aware of any Holocene eruptions from Cerro del Azufre. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Cerro del Azufre 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 large volcanic complex at the center of this NASA Space Shuttle image (with north to the upper right) is Cerro del Azufre. The 5846-m-high volcano lies just west of the Bolivian border, south of Salar de Ascotán (the light-colored area at the upper right). A youthful lava dome forms a small circular area below and to the right of the center of the image, and the Holocene San Pedro-San Pablo volcanic complex lies at the left-center.

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.
