| dc.description.abstract | The paper assess the potential volcanic hazards pose by a Holocene Gebalaytu and Kurub volcanoes which are situated in the central afar depression at top of Tendaho Graben and adjacent to the active recent Manda-Harraro rift and west of Semera town about 5km and SE of the Manda -Harraro volcanic complex in the South Danakil region respectively. The petrographic and geochemical analysis of the volcanic rock is used to constraint the volcanic evolution and the origin of magma as a result the high Fe2O3 content of Gebalaytu rock tend to show tholeiitic affinity and sub alkaline group while Kurub volcano shows much more high Fe2O3 content however the Magma type is MORB at plate divergent and partial melting of the mantle since afar mantle plume is pushing the continental crust in afar. The associated rhyolitic rocks are formed by fractional crystallization of the basalt with little or no crustal contamination. The volcanoes have proximity to Semera city, Semera University, dry port a geothermal power sites, the Tendaho sugar estate and the Tendaho dam and water reservoir. The main road from Addis Ababa to Djibouti passes through the town and small villages around the volcanoes. The Tendaho graben as a whole is shows a potential of geothermal with different fumarolic activity Gebalaytu and Kurub volcanoes may pose potential hazards to population and important infrastructure. An assessment of the potential volcanic hazards from future eruption has been attempted based on the volcanoes past eruptive history. Tentative volcanic hazard maps and zones have been produced from four identified vents for Gebalaytu and one central vent for Kurub affecting an area over a moderate distance of 10km radius. | en_US |
