Bal Haf

The Balhaf-Bir Ali Volcanic Field along the Gulf of Aden in southern Yemen contains cinder cones associated with vesicular lava flows and scoria cones. The 500 km2 field lies along the Gulf of Aden about 120 km SW of the city of Al Mukalla. Lava flows covered much of the area and created an irregular shoreline. One fresh-looking basaltic flow may be of historical age (Catalog of Active Volcanoes of the World). The At-Tabâb tuff cone along the coast rises about 200 m from the sea 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 contains a lake.
