Zusammenfassung |
A stacking method to detect very weak signals is introduced in this paper.
This method is to stack observed data in different well known periodicities
according to the astronomical clock since majority geophysical observations
are time based. We validated this method by applying it in four different
cases. Interactions behind the observed parameters become obviously after it
is stacked in two diurnal and semidiurnal tidal periodical waves. Amplitude
and phase variations will be also measurable when a sliding windows stacking
is used. This could be an important reference to find precursors before some
earthquakes and volcanic events, corresponding to attenuations of medium
patterns. |
