    Electrical resistivity methods in geophysical prospecting have been the most powerful
    tool in geothermal exploration. Determination of geoelectric strike angle in magnetotelluric
    (MT) measurements is a valuable contribution to an overall analysis of
    resistivity data. Among the applications of the strike analysis are the delineation of
    the boundaries of geothermal reservoirs and determination of fractures and faults
    at different depths which are the ideal flow paths of geothermal fluid. Strike analysis
    reveals complexity of resistivity structures within geothermal areas. Four MT
    soundings were conducted on Reykjanes peninsula in May 2014 and the data were
    compared with results of strike analysis from Krafla and Námafjall. Similarity in
    geoelectric strike behaviour in high-temperature areas confirms the results of inversion
    of resistivity soundings. The strike angle is found by rotation of the impedance
    tensor by a certain angle which in turn minimizes diagonal tensor elements Zxx
    and Zyy.
