Harra of Arhab volcano is an active volcanic field ca 30 km north of the Yemen's capital Sana'a.
The volcanic field of stratovolcanoes, cinder cones and lava flows covers about 1500 sq km, and has last erupted between 400 and 600 AD when it produced a cinder cone and a 9 km long lava flow. The only other known historic eruption occurred around 200 AD.

Background:

The Harra of Arhab volcanic field (also known as the Sana'a or the Sana'a-Amran volcanic field) forms a 100-250-m-thick basaltic plateau capped by a few small stratovolcanoes and about 60 scoria cones, 2 of which have erupted in historical time.
Cones in the volcanic field are commonly aligned along a north-NW trend. The composition of the lavas as dominantly basaltic-to-hawaiitic.
