The mainlyQuaternaryHarra of Arhabis the northernmost, historically activevolcanic field(Arabic:حَرَّة,romanized:Ḥarrah) inYemen.Also known as the "Sana'a-'Amranvolcanic field ", or simply the" Sana'a volcanic field ",[1]it has erupted in ancient times.[2][3][4]
Morphology
[edit]The field is located on a 1500 km2volcanic plateau. The plateau contains a few small (older)stratovolcanoesand 60volcanic cones.The field is arranged on a north-northwest line. Youngerbasalticrocks from thePliocene-Holocene(northern end of the field), overlieRhyoliticrocks from theOligocene-Miocene,which covers most of the field. The volcano is located 30 km (19 mi) north of Yemen's capital city, Sana'a.[2][3][4]
Eruptions
[edit]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 Hattabcinder cone.It produced a lava flow that travelled for 9 km (5.6 mi), and caused some damage.[2][3][4]
