The extensive Pliocene-to-Holocene Haruj volcanic field covers a broad 45,000 sq km area in central Libya and contains very well-preserved basaltic scoria cones, lava flows, and explosion craters. The youngest lava flows of the Haruj field (also known as Al-Haruj al Aswad or Djebel Haroudj) were considered by Klitzsch (1968) to be Holocene in age and are located at the northern side of the field. The Haruj field contains about 150 volcanoes, 30 of which are small shield volcanoes with heights of between 100 and 400 m. The Haruj volcanics are located along the SE extension of the Hon graben system of late Cretaceous to Tertiary age, near the intersection of the Paleozoic southern Haruj uplift and the western edge of the Mesozoic Tibesti-Sirte uplift.
The Global Volcanism Program is not aware of any Holocene eruptions from Haruj. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Haruj 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 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.
