Long-form identifier:

GUID (UUID V4):

Extensive lava field comprising 3 coalescing fields Ar Rukhq, Turrah and Rashid-Bani Abdullah, the principal part of which extends 310km N-S and 75 km E-W, although some basalt flows extend for up to 100km from the central complex (Camp & Robool 1989, 1991). The most northerly part of the field is referred to as Harrat Al-Madinah by Moufti et al. (2013).

The whole field comprises 36 shield volcanoes, 644 scoria cones, 24 domes, associated with benmoreite and trachyte pyroclastic activity, and fewer necks and plugs (Camp & Roobol 1989).

The most recently recorded eruption was in 1256 AD.
