EARTHQUAKE PRECURSOR RESEARCH

times of recent worldwide earthquakes, as recorded by the Elfrad Group

This graph shows the electrical precursor and seismic activity, before and during this earthquake, that occurred in Sumatra, Indonesia, which is located 16559 kilometers distant. Note the precursor activity which began at 15:01:49 UT. These ULF electrical signals were detected 86.56 minutes prior to the earthquake and the transmissions were very intense in amplitude.
An unusual aspect of this precursor indication, is the abrupt shift in DC voltage polarity which is shown by the "P" indicator in the above graph.
The graph below points a little more clearly to this shift. The Amity detection station where this data was recorded is on the opposite side of the earth, so the event causing this polarity shift was large enough to affect the entire globe. There is speculation that the ongoing Solar activity with it's extremely intense magnetic may have been the trigger. This data supports that theory. ©2000
