In this thesis work integrated geophysical techniques, involving electrical resistivity, gravityrnand magnetic surveys have been carried out over the Corbetti Caldera in the central MainrnEthiopian Rift (CMER) to verify the geothermal potential of the caldera. Corbetti geothermalrnprospect is located about 250 km south of Addis Ababa and 20kms from Awassa and the arearnis bounded by Lake Awassa to the south and Lake Shalla to the north with geographicrnlocation between latitude 7.170N-7.250N and longitudes 38.300E-38.470E.rnThe Corbetti Caldera is characterized by Quaternary volcano tectonic activity which isrnmainly silicic volcanism and a resurgent caldera structural system. The Quaternary volcanismrnis associated with a wide spread of steaming ground and fumarolic activity which evidencedrnthe existence of a heat source at depth.rn56 VES points, 200 gravity and about 200 magnetic data have been used and analyzed andrnresults are presented as magnetic, gravity and electrical counter map for qualitativerninterpretation and also gravity and magnetic 2-D model constrained with Geoelectric sectionrnfor quantitative interpretation.rnThe complete Bouguer gravity anomaly in conjugation with total magnetic field anomalyrnmap of the area indicates the existence of intrusion beneath the caldera, i.e. the highestrnBouguer gravity anomaly resulting from the higher density of the intrusion correspondinglyrnthe shallower heat source caused by this intrusion is characterized by the lowest magneticrnanomaly response.rnResults from vertical electrical soundings along profile-2 indicates the presence of middlernthicker conductive zone which is associated with the increase in temperature and alteration ofrnrocks and apparent resistivity map for AB/2=1810m and AB/2=2700m shows low resistivityrnanomaly follows the eastern and northern caldera rim, stretching north of the caldera towardsrnLake Shalla.rnBased on the joint analysis of data from these geophysical methods and thermalrnmanifestations in the area, the area has the potential for large scale electrical powerrndevelopment. Besides, additional geophysical methods are proposed to further reinforce thernoutcome of the study.
