South Island (left center) is the southernmost and largest of the three volcanic islands in Lake Turkana. North is to the left in this Space Shuttle view. Fresh-looking lava flows, erupted from a fissure extending the 11-km length of the island, form much of the eastern (top) shoreline. The basaltic lava flows are morphologically similar to youthful Holocene flows of The Barrier volcano, whose lower flanks can be seen at the far right. An eruption from a scoria cone on South Island was witnessed during Count von Teliki's 1888 expedition.

South Island (right) is the southernmost and largest of the three volcanic islands in Lake Turkana. The island (sometimes referred to as Hohnel Island) contains numerous tuff cones and rises 320 m above the lake surface. Fresh-looking lava flows, erupted from a N-S fissure extending the 11-km length of the island, form much of the eastern shoreline. An eruption from a scoria cone on South Island was witnessed during Count von Teliki's 1888 expedition.
