Harra of Arhab volcano eruptions: 500 AD ± 100 (south flank of Kaulet Hattab), around 200 AD (east flank of Jabal Zebib) Last earthquakes nearby:
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. |
