This graph shows the electrical precursor and seismic activity before and during this earthquake which occurred in the Tonga Islands. The above graph is a recording of signals for a duration of 4 hours starting at 14:00 hours UT, 01/08/2000. The red markers indicate the various seismic wave disturbances during and after the earthquake, the green markers indicate the electrical signals generated through the earth before, during, and after the event. The green arrow on the left, indicates the start time of the electrical signals and transients before the seismic disturbances began. These continued for a period of 131.5 minutes before the actual earthquake. The frequency of interest is a band between .02 and .04 hertz. These signals have been consistent with every major earthquake which has been recorded during the past year. It seems there is a window starting around three hours before each major event, which can be used to forecast impending major seismic movements. Please keep in mind we are detecting these precursors using underground antennas and are not receiving these signals using the conventional method of electromagnetic detection through the atmosphere. ©2000
