  • Patent number: 5514963
    Abstract: A method for monitoring an area of the surface of the earth uses measurement probes arranged in a grid for determining the self-potential with respect to a base probe. The measurement probes are interrogated repeatedly. The earth resistance between measurement probes and the base probe is also measured repeatedly between measurements of self-potential. Potentials on the surface of an area of the earth can be determined precisely, independently of earth-resistance changes.
