El Negrillar is a group of cinder cones and compound andesitic lava flows in what was interpreted to be a Holocene volcanic field west of the Cordón de Púlar (Moreno 1985, pers. comm.; de Silva and Francis, 1991). Gardeweg (1993, pers. comm.), however, did not consider El Negrillar to be of Holocene age. This volcanic field, also known as Negros de Aras, lies about 20 km north of Socompa volcano. The major Holocene debris avalanche from Socompa overlies some youthful-looking lava flows at the western margin of El Negrillar lava-flow complex.
The Global Volcanism Program is not aware of any Holocene eruptions from El Negrillar. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the El Negrillar 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.
|Negros de Aras|
|The dark-colored lava flows and cinder cones at the center of this NASA Landsat image (with north to the top) is El Negrillar. This group of cinder cones and compound andesitic lava flows of Quaternary age, also known as Negros de Aras, lies about 20 km north of Socompa volcano. The lighter-colored area on the left side of the image abutting El Negrillar flows on the west is part of the major Holocene debris avalanche from Socompa 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.
