Geothermal phenomena in form of a d n a a g i l U fumaroles, hot springs, steam jets, geysers, a KENYA L. Turkana m o sulphur deposits and high geothermal gradient S Nairobi expressed by anomalously hot ground and anomalous groundwater manifest the area. Tanzania Mombasa Detailed surface exploration surveys carried Barrier out in the prospect indicate presence of low to Namarunu 2oN intermediate temperature fracture controlled Emuruangogolak geothermal system(s) in the area. Silali Paka These low to medium enthalpy resources can Korosi be utilized in direct uses and electric power L. Baringo generation using binary-cycle power plants. L.
