<p>A method of detecting precursor seismic electromagnetic waveforms and predicting future seismic activity in the form of an earthquake by placing a detector including a dielectric material (81) in contact with the earth. The detector receives at the dielectric material (81) precursor seismic electromagnetic waveforms traveling within the earth emanating from a region of seismic activity. A sensor (82a, 82b, 82c) responsive to the dielectric material (81) senses a series of individual discrete material wherein each of the signals has the characteristic of a rise time that is shorter than its fall time. Alternatively, the discrete signals may be a single discrete signal characterized by a plurality of overlapping waveforms. The predicting based on the series of the signals the occurrence of the earthquake.</p> |
