Isola di Jabal al-Tair

Tair, Jebel at

Stratovulcano · Yemen · 244 m

Plumes are visible from the eruption of Jebel at Tair rise above the volcano as seen from the U.S. Navy vessel USS Bainbridge on 2 October 2007, two days after the start of the eruption. The small, 3-km-wide island rises from a 1,200 m depth in the south-central Red Sea. Jebel at Tair (one of many variations of the name, including Djebel Teyr, Jabal at Tayr, and Jibbel Tir) is the northernmost known Holocene volcano in the Red Sea. Historical eruptions date back to the 18th century.

Sintesi geologica

The basaltic Jebel at Tair volcano rises from 1,200 m depth in the south-central Red Sea, forming an oval-shaped island about 3 km long. It is the northernmost known Holocene volcano in the Red Sea and lies SW of the Farisan Islands. Youthful basaltic pahoehoe lava flows from the steep-sided central vent, Jebel Duchan, cover most of the island, draping a circular cliff cut by wave erosion of an older edifice and extending beyond it to form a flat coastal plain. Pyroclastic cones are located along the NW and S coasts, and fumarolic activity occurs from two uneroded scoria cones at the summit. Radial fissures extend from the summit, some of which were the sources of lava flows. Explosive eruptions were reported in the 18th and 19th centuries, prior to an eruption in 2007-2008.
