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.

Resumen geológico

The Barrier volcanic complex separates Lake Turkana from the broad Suguta Trough to the S, the site of a former lake. The volcano is comprised of four overlapping shield volcanoes, with the youngest, Kakorinya, located over the axis of the East African Rift. Kalolenyang volcano lies W of Kakorinya, and Likaiu West and Likaiu East are located to the ENE. A 3.8-km-wide summit caldera was formed at Kakorinya about 92,000 years ago. Youthful-looking trachytic and phonolitic lava domes and flows erupted within the caldera and along its ring fracture fill much of the caldera floor. Early Holocene fissure-related scoria cones and lava flows dot the S and N flanks. Solfataric fields are located within the caldera and on the W and S flanks. Historical eruptions from Teleki's and Andrew's cones on the N and S flanks, respectively, have produced basaltic explosive activity and lava flows during the 19th and 20th centuries.

Resumen de Wikipedia

El Barrier es un volcán en escudo del Valle Suguta. Recibe su nombre porque forma una barrera de unos 20 km separando el valle del Suguta del lago Turkana.
