Electrical Resistivity of the Geo-Materials in Monitoring the Earthquake Prediction

U. P. Verma, Shankar Dayal

Abstract: Electrical resistivity's of the geomaterials directly or indirectly depends on Temperature condition controlled by the geothermal energy. As one of rhe salient precursors of the earth quakeRsisistivities of the geo_materials decreases with the insuring earthquake at the 2nd stage: Rikitake (1976), Bolt1988, 1993 but on the recommendation of thermodynamic principle. In the Equation ?t=?0(1+?t) dependence of resistivity of geomaterials are never uniform for ranging from conductor to semicunductors:1at higher range of temperature. On the base of thermodynamics, caliberation of temperature affecting the resistivity of the material can be simulated with the equivalent amount of seismic energy >5 Mw magnitude. Time of ground motion can be predicted with the Gutenberg?s Frequency ?Magnitude relationship2.With the Stacey?s conservation equation3 accumulated thermal energy can be transformed into mechanical energy (stress) sufficient for seismicity on the given area for given period on site of observation.
