The Mega Basalt field, straddling the Ethiopia-Kenya border, is referred to in Kenya as the Dukana volcanic field. The Ethiopian portion was considered to have been active during the Holocene (Mohr, 1979; Davidson, 1983). The Kenyan portion was mapped as Pleistocene in age, with one Potassium-Argon date of about 0.9 million years ago (Charsely, 1987). The 1.8-km-wide Gof Dukana basaltic maar is surrounded by ejecta containing abundant basement igneous and metamorphic rocks. About 50 pyroclastic cones with associated lava flows rise to about 150 m above the lava platform in northern Kenya.

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

Pyroclastic cones of the Mega Basalt field dot the center of this NASA Landsat image (with north to the top). The volcanic field, straddling the Ethiopia-Kenya border, which cuts diagonally across the image from the upper left to lower right, is referred to in Kenya as the Dukana volcanic field. The volcanic field includes the 1.8-km-wide Gof Dukana basaltic maar, and about 50 pyroclastic cones with associated lava flows rise to about 150 m above the lava platform in northern Kenya.

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.
