지질학적 요약
The Hanish Islands are formed from a series of volcanic vents along a NE-SW trend, and include the Holocene Great Hanish, Little Hanish, and many other small islands and submarine shoals. The Zukur-Hanish island group lies in shallow waters S of the Red Sea median trough. Spatter cones, cinder cones, and ash cones line the crest of the 20-km-long Great Hanish Island. Short lava flows reach the coast on both sides of the island. Initial eruptions were phreatic, followed by the formation of basaltic cinder cones, spatter cones, and fluid lava flows.
