The Korath Range is an isolated group of tuff cones and lava flows in southern Ethiopia that were erupted along the Turkana Rift, which extends north from Kenya. About 20 tuff cones occupy the Korath Range, many of which issued lava flows from their flanks that traveled up to about 5 km. The apparent youngest flow issued from the central crater and flowed through a breach in its rim. The absolute age of the dominantly basanitic-tephritic lava flows is unknown, but a shell adhering to the youngest flow was radiocarbon dated at 7900 years before present (BP) (Brown et al., 1969). Davidson (1983) indicated an age between 30,000 BP and 7900-9500 BP.

The Global Volcanism Program is not aware of any Holocene eruptions from Korath Range. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Korath Range 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 fissure-controlled Korath Range is an isolated group of tuff cones and lava flows in southern Ethiopia that were erupted along the Turkana Rift. The Korath Range tuff cones issued many lava flows that traveled up to about 5 km, forming lobate margins, most prominently on the western flanks of the massif. The apparent youngest flow issued from the central crater and flowed through a breach in its rim.

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.
