Classification of Surface Geoelectric Arrays

P107 Classification of Surface Geoelectric Arrays S. Szalai* (Geodetic & Geophysical Research Institute of HAS) & L. Szarka (Geodetic & Geophysical Research Institute of HAS) SUMMARY We have found in the geophysical literature more than ninety different surface geoelectric arrays fulfilling an updated definition (specifying the current feeding the potential difference measurement and the geometry of the electrodes). Several composite configurations with widely varying geometry have also been collected. We have presented the geoelectric arrays in a systematic way and with a unified notation. The classification is based on three divalent parameters: “superposition” of measurements “focusing” of currents and “colinearity”
