The Assab volcanic field near the Red Sea coast in southern Eritrea forms a spectacular range of basaltic cinder cones and associated lava flows. The massive lava field covers a 55 x 90 km area, and flows reached the Red Sea along a broad front. The vents of the Assab volcanic field, also known as Ado Ale or Ud'ale, were constructed along a broad E-W-trending line that extends to the coastal city of Assab.

The Global Volcanism Program is not aware of any Holocene eruptions from Assab Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Assab Volcanic Field 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.

The long chain of pyroclastic cones and lava flows extending East-West across this Landsat image is the Assab volcanic field near the Red Sea coast in southern Eritrea. This spectacular range of basaltic cinder cones and associated lava flows covers a 55 x 90 km area, and flows reached the Red Sea along a broad front. The vents of the Assab volcanic field were constructed along a broad E-W-trending line that extends to the coastal city of Assab, out of view to right.

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.
