The massive Atakor volcanic field is the largest in the Hoggar (or Ahaggar) volcanic province of southern Algeria and covers an area of 2150 sq km. Basaltic (mostly basanitic) scoria cones and lava flows of Pleistocene-Holocene age lie near spectacular older trachytic and phonolitic lava domes and volcanic necks that form some of the most dramatic scenery of northern Africa. The latest stage of activity began around 1.95 million years and continued almost to the present. Lava flows cover Holocene lake sediments dated at about 10,000 year Before Present (BP) and alluvial terraces in which Neolithic artifacts have been found. Historical pottery has been found within lava flows in the Tahifet area, and oral traditions of the Tuareg people also suggest that eruptions were witnessed. Sporadic fumaroles and persistent small-scale seismicity has been noted during historical time.

The Global Volcanism Program is not aware of any Holocene eruptions from Atakor Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Atakor Volcanic Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Atakor Volcanic Field.

The bluish-gray area at the center of this NASA Landsat image and areas at the upper right are part of the massive Atakor volcanic field. These volcanics cover an area of 2150 sq km and include spectacular lava domes and volcanic necks and abundant basaltic scoria cones and lava flows. Historical pottery has been found within lava flows in the Tahifet area, and oral traditions of the Tuareg people also suggest that eruptions were witnessed. The prominent lineament at the far left is the Inter-terrane Pan-African shear zone.

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.
