Bal Haf, Harra of
"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-Tab├ób 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."  -Smithsonian Volcano Archive
