Harra es-Sawad

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

Morphology
The field stretches for around 100 km, contains around 100 volcanic cones, and is orientated on a WSW-ENE line. This has produced a 40 x lava field, which is mostly Holocene in age, and covers faulted basement limestone. Many of the fields cones are young and uneroded.

History
The only eruption that has been noted in historical times occurred in 1253. This eruption was a large VEI 3 eruption, although it was poorly documented. Given the age of the field, other eruptions may have occurred in the recent past.
