BackgroundThe 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.
