About Zuqar Island

1. Geographic Location: Yemeni island in the southern Red Sea, forming part of the Hanish Islands archipelago near the strategic Bab-el-Mandeb Strait.
2. Spatial Extent & Position: Covers ~130 sq km; physically closer to the African continent but politically part of Asia.
3. Geopolitical Dispute & Settlement: Ownership resolved via Permanent Court of Arbitration (PCA) ruling in 1998 following the 1995 Hanish Islands Conflict, awarding sovereignty to Yemen.

Geological Features

1. Volcanic Origin: Formed by a shield volcano topped with basaltic cinder cones.
2. Lava Features: Characterized by smooth, ropy pahoehoe lava flows.
3. Coastal Cones: Islets and coastal cones around the island formed by phreatic eruptions, which are steam-driven blasts caused when magma heats groundwater.
4. Tectonic Setting: Driven by seafloor spreading in the Red Sea rift zone between the African and Arabian plates.

Pahoehoe Lava

1. Physical Surface: Smooth, shiny basaltic lava featuring characteristic ropy folds.
2. Flow Dynamics: Low viscosity and high fluidity, spreading in thin sheets through internal lava tubes.
3. Comparison with Aa Lava: Unlike Pahoehoe, Aa lava is cooler, highly viscous, and forms a rough, jagged, clinkery surface. (Both are terms of Hawaiian origin).

Strategic Significance of Zuqar Island

1. Maritime Chokepoint: Guarding the approach to the Bab-el-Mandeb Strait, connecting the Red Sea to the Gulf of Aden.
2. Global Trade Trade Route: Serves as the crucial southern gateway to the Suez Canal, critical for energy security and Asia–Europe trade flows.
3. India’s Strategic & Economic Interests: Regional instability increases maritime shipping costs, delays supply chains, and threatens safety of Indian seafarers.
4. Regional Security Risk: Armed conflicts near the Hanish Islands pose continuous threats to global freedom of navigation and commercial shipping.

Q2. What is pahoehoe lava?
