Overview

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.

Regional Volcanic Activity

The Eastern Africa Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Zukur (Zugar), the northernmost large island of the Zukur-Hanish island group in the southern Red Sea, is seen in this NASA Landsat image (with north to the top). Numerous young basaltic 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.
