Enclosed is the data scan during the Andreanof Islands event. Note that reception was better on the East-West antenna array. Also note there was no noticeable time delay so apparently the signals were generated by pizeoelectrical activity.
Precursor signal activity is evident for at least 30 minutes prior to this quake. I have noticed this is also the case in other earthquakes of this size.
