ABSTRACT:
An apparatus and a method for predicting an earthquake are disclosed. The apparatus employs a set of two electrodes for measuring the vertical component of the gradient of the electrical field due to the capillary movement and the surface evaporation of the ground water, a humidity sensor for measuring the humidity of the soil surface, and a temperature sensor for measuring the temperature of the soil surface. The correlation coefficient between the changes in the electrical field gradient due to changes in the surface temperature related to the water evaporation from the soil surface is calculated. The correlation coefficient changes its sign at the time of appearance of the earthquake precursor.
