The following pages show the detection times of recent worldwide earthquakes as recorded by Elfrad

Afghanistan  16:44:43.4 UTC  35.1N  71.9E  226Km MS=6.2

This graph was recorded from the Amity Hill location. The epicenter was deeper than usual at 226 kilometers below the surface of the earth. The electrical activity was also stronger than normal for a quake of this magnitude.  A strong precursor signal was radiated through the earth and was detected 157 minutes before the initial shock.  The strong signals to the right of the "S" indicator were very likely caused by the piezoelectric effect of  the pressure wave as it passed through the area 24 minutes after the event.  This pressure wave can be detected by seismic equipment which records earth movement.

The above graph indicates the intense buildup of  ULF electromagnetic signals before the actual event. A normal background reference  signal level with no pending earthquake is 25 to 75 millivolts.  As shown in the graph the "P" indicator is pointing to 200 millivolts peak to peak one hour before the event.  Just seconds before the first shock, the stress is so great that over 2000 millivolts of signal was recorded.    This detection of this precursor and the recording of  ULF signals was accomplished  from a distance of  11663 kilometers.  1999
