Geological Summary

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 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.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
