The following pages will show the detection
times of recent worldwide earthquakes as recorded by Elfrad
Alaska Peninsula 13Oct1999 01:33:40.3 54.7N 161.2W 33 MS=6.3
Again the "P" indicator points to the time of the event and the "S" indicator shows the detection time of precursor activity. ( 90 min.)Please note the extremely high peaks which show unusual transient activity. This possibly could be caused by piezoelectrical effects due to stress build up and movement in the interior of the earth. This same pattern was also noticed during the earthquake in Taiwan.
