Case Study 3. East Africa – Volcanoes, Glaciers and Safari Parks: M. Cooper
In East Africa, crustal spreading processes have already torn Saudi Arabia away from the rest of the African continent, forming the Red Sea. The actively splitting African Plate and the Arabian Plate meet in what is known as a triple junction (Afar, see Chapter 3), where the Red Sea meets the Gulf of Aden. A new spreading centre may be developing under Africa along the East African Rift Zone, and if spreading continues the three plates that meet at the edge of the present-day African continent will separate completely, allowing the Indian Ocean to flood the area and making the easternmost corner of Africa (the Horn of Africa) a large island (Kious and Tilling, 1996).
