Zukur (Zugar), the northernmost large island of the Zukur-Hanish island group in the southern Red Sea, is formed of Holocene basaltic pyroclastic cones and spatter cones that issued youthful-looking pahoehoe lava flows. This island group, in contrast to other Red Sea islands such as Jebel at Tair or the Zubair Islands, lies in shallow waters south of the Red Sea median trough. Products of phreatic eruptions at Zukur form small islands and coastal cones. Late-stage trachytic lava domes produced viscous lava flows. Vents on Zukur are aligned along a NE-SW trend.

Numerous young basaltic pyroclastic cones and spatter cones were the source of pahoehoe lava flows. Products of phreatic eruptions at Zukur form small islands, such as Shark and Near Islands off the SW coast of Zukur. Vents on Zukur are aligned along a NE-SW trend, as seen on the peninsula at the southern tip of the island.
