Jalua, the northernmost volcano in the Eritrea/Ethiopia area, occupies an isolated location in the arid Danakil depression. It contains a large, central volcanotectonic depression that is open to the Zula Gulf and an isolated central cone. Jalua lies NW of basaltic lava flows of the Alid graben and south of the Zula Gulf. No historical eruptions are known, although fumarolic activity continues on its western flank. The nomenclature of volcanic features in the Afar region reflects that of the two dominant ethnic groups, the Afar (on the Ethiopian side) and the Issas (in the SE Afar depression). Each group has their own names for physiographic features, and consequently more than one name may apply to the same feature. A similar situation occurs throughout Ethiopia, where names often reflect local politics.

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

Jalua volcano, at the upper left, lies NW of the basaltic lava flow field that extends from Alid volcano (the light-colored volcano at the lower left capped by a single small cloud) and is the northernmost volcano in Ethiopia. Jalua contains a large, central volcanotectonic depression that is open to the Zula Gulf, just visible at the extreme upper left. No historical eruptions are known from Jalua, although fumarolic activity continues on its western flank.

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.
