Barrier, The

Type
Shield volcano
Elevation

Last eruption

A northward-looking aerial view shows the summit caldera of Kakorinya volcano of The Barrier volcanic complex with Lake Turkana in the distance. The 3.8-km-wide summit caldera was formed about 92,000 years ago, and post-caldera lava domes and flows fill much of the caldera floor. Fresh-looking lava flows and tuff cones occur along the shores of Lake Turkana. Teleki's Cone on the northern flank and Andrew's Cone (lower left foreground) on the southern flank have been the source of historical lava flows.
