Zukur Volcano — Yemen

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 lies in shallow waters S of the Red Sea median trough. Products of phreatic eruptions 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.
