The mainly Quaternary Harra of Arhab is the northernmost, historically active volcanic field (Arabic: حَرَّة, romanized: Ḥarrah) in Yemen. Also known as the "Sana'a-'Amran volcanic field", or simply the "Sana'a volcanic field", it has erupted in ancient times.

Morphology

The field is located on a 1500 km volcanic plateau. The plateau contains a few small (older) stratovolcanoes and 60 volcanic cones. The field is arranged on a north-northwest line. Younger basaltic rocks from the Pliocene-Holocene (northern end of the field), overlie Rhyolitic rocks from the Oligocene-Miocene, which covers most of the field. The volcano is located 30 km (19 miles) north of Yemen's capital city, Sana'a.

Eruptions

A historical eruption in 200 AD (a VEI 2) took place on the flank of an older cinder cone (Jabal Zebib). Another eruption from the volcano in around 500 AD took place on the south flank of Kaulet Hattab cinder cone. It produced a lava flow that travelled for 9 km (5.6 miles), and caused some damage.

Note: Mountains are sorted in alphabetical order, unless where it concerns ranges. The highest confirmed mountains in each country are indicated with 'HP', and those with the highest peak are indicated with 'HP', bearing in mind that in the UAE, the highest mountain and the mountain with the highest peak are different. Outcrops are indicated with 'OC', and outliers with 'OL', and anticlines with 'AC'. Volcanoes are indicated with 'V', volcanic craters with 'VC', lava fields with 'LF', and volcanic fields with 'VF'.
