Harra es-Sawad, or the "Shuqra Volcanic Field",[1] is a large trachybasaltic volcanic field that runs along the Gulf of Aden.

[2][3] The field stretches for around 100 km (62 miles), contains around 100 volcanic cones, and is orientated on a WSW-ENE line.

This has produced a 40 km × 95 km (25 by 59 miles) lava field, which is mostly Holocene in age, and covers faulted basement limestone.

[1][2][3] The only eruption that has been noted in historical times occurred in 1253.

Given the age of the field, other eruptions may have occurred in the recent past.
