Analysis and interpretation of magnetotelluric data in characterization of geothermal resource in Eburru geothermal field, Kenya

•Eburru geothermal field is located on the southern segment of Kenyan Rift and forms the highest topography within the entire Kenyan Rift at an elevation of 2800 m.•The magnetotelluric method was used to assess the extent of the geothermal resource in Eburru geothermal field.•A 2-D MT inversion was performed to generate resistivity models of the field.•Given its ability to recover complex resistivity models for the ground, three dimensional (3-D) MT inversion was also carried out and both inversion approaches gave similar resistivity structures.•The resistivity profiles analyzed revealed a structure of low resistivity (
