Geological Summary

Jabal Yar, the southernmost young volcanic field in Saudi Arabia, is a small olivine basaltic field along the Red Sea coast at the SW tip of Saudi Arabia. It contains three groups of volcanoes, Qummatain, Djar'atain-Harra, and 'Ukwatain. Hot springs occur south of Djar'atain and between it and 'Ukwatain. A single historically documented eruption took place at the beginning of the 19th century.

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.
