The isolated Wau-en-Namus volcanic field (also spelled Waw an Namous or Uaw en Namus) lies in the Sahara desert of south-central Libya, south of the Haruj volcanic field. A 4-km-wide, 100-m-deep caldera contains a post-caldera scoria cone, Wau-en-Namus. An apron of dark basaltic tephra extends 10-20 km around the caldera in stark contrast to the light-colored desert sand prominent in satellite views. Three small salt lakes of variable color contribute to the name of the volcano, which means "Oasis of Mosquitoes." The youthful appearance of the central cone has suggested it may be as young as a few thousand years, although the arid climate may mask its actual age. Yellow sulfur deposits are found in the 150-m-wide crater. Other basaltic lava flows occur several tens of km NW of the volcano.
The Global Volcanism Program is not aware of any Holocene eruptions from Wau-en-Namus. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Wau-en-Namus 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.
|Uau en Namus | Waw an Namous|
|The central cone of the isolated Wau-en-Namus volcanic field lies within a 4-km-wide caldera in the Sahara desert of south-central Libya. Three small salt lakes, one of which is seen at the right margin of the cone in this view from the south, contribute to its name, which means "Oasis of Mosquitoes." The youthful appearance of the central cone has suggested it may be as young as a few thousand years, although the arid climate may mask its actual age.

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.
