The Harra of Bal Haf is a small volcanic field along the Gulf of Aden in southern Yemen that contains tuff cones and large aa lava fields. The volcanic field lies along the coast about 100 km SW of the city of Al Mukalla. Lava flows erupted from cinder cones blanket much of the volcanic field and produce an irregular shoreline. One fresh-looking basaltic flow may be of historical age (Catalog of Active Volcanoes of the World). At-Tabâb tuff cone along the coast rises from the sea to 233 m and has a 1.5-km-wide crater partially filled by a cinder cone and associated lava flows. An adjacent tuff cone to the east is lake filled.

The Global Volcanism Program is not aware of any Holocene eruptions from Harra of Bal Haf. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Harra of Bal Haf 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 Harra of Bal Haf volcanic field fills much of this NASA Space Shuttle image taken along the Gulf of Aden in southern Yemen (with north to the lower left). Dark-colored lava fields cover much of the volcanic field and create an irregular shoreline. One fresh-looking basaltic flow may be of historical age. Two large tuff cones are visible along the coast at the upper left, one of which is lake filled. A road cuts across the volcanic field from the town of Bal Haf at the lower 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.
