Study of the temporal correlations in the magnitude time series for the Greek earthquakes by means of the Detrended Fluctuation Analysis DFA
Summary:
Detrended Fluctuation Analysis (DFA) is applied to the time series of the
earthquake magnitudes in Greece according to the NOAIG catalog of the Institute
of Geodynamics in the National Observatory in Athens. A crossover scale is
observed in which the long range correlation properties of this time series
change. This result is similar with the findings in other seismic active areas,
such as Japan and California. A study of the crossover is carried out versus
the magnitude threshold of the catalog per decade. Results concerning the
completeness magnitude threshold of the catalog (without using the magnitude
distribution) and the behavior of the long range correlations per decade are
obtained.
