| The Quaternary Harra of Arhab lava field in Yemen, north of the capital city of Sana'a, consists of a 1500 sq km basaltic plateau capped by a few small stratovolcanoes and about 60 scoria cones, two of which have erupted in historical time. Cones in the volcanic field (also known as the Sana'a or the Sana'a-Amran volcanic field) are commonly aligned along a north-NW trend above a 100-250-m-thick volcanic plateau. Pliocene-to-Holocene volcanic rocks have a dominantly basaltic-to-hawaiitic composition and overlie the northern end of an area of extensive Oligocene-Miocene basaltic-to-rhyolitic rocks that extends to the SW tip of the Arabian Peninsula. The latest eruption at Harra of Arhab took place in pre-Islamic time between about 400 and 600 AD and produced a lava flow that traveled 9 km. | |||
