Geological Summary

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.

WOVOdat WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

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.
