ABSTRACT:
A method of forecasting earthquakes as a function of transient variations in electric earth currents and apparatus for practicing such method. Transient variations in earth currents are detected from electrodes buried in the earth and portions of the transient variations within preselected frequency ranges are selected. The amplitude of such portions are then compared to predetermined standards for predicting magnitude, location and/or time of occurrence of an impendent earthquake.
