These pages show the detection times of recent worldwide earthquakes, as recorded by the Elfrad Group

Michoacan, Mexico   08/09/00  11:41:47.8   18.2N  102.1W  Depth= 33 Km M= 6.4 

This graph shows the electrical precursor and seismic activity, before and during this earthquake, that occurred in Michoacan, Mexico, which is located 2871 kilometers distant. Note the precursor activity which began at 8:08:08.0 UT.  These ULF electrical signals were detected 213.35 minutes prior to the earthquake and the transmissions were very intense in amplitude. The above graph shows data recorded for a duration of 6 hours before and during the event. Note the increase of activity in the frequency band of .02 to .04 hertz. until and during the first shock. 

The graph below indicates the same time span however the data was recorded from the East West array. This screen shot shows more clearly the pulse activity caused by abrupt earth movements, due to the orientation of the detection array.  The event was located due south of the event and captured the electromagnetic vector component of the signals.                                                                        2000
