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.

地質学的概要

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.

Wikipedia の要約

Zuqar Island is a Yemeni island located in the Red Sea. It lies between the coasts of mainland Yemen and Eritrea, near the Bab-el-Mandeb strait which connects the Red Sea to the Gulf of Aden. Despite its proximity to the African continent, the island is considered a part of Asia because it sits on the Asian continental shelf. It is approximately 130 square kilometres (50 sq mi).
