| Zusammenfassung |
| In the present work the statistical properties of the earthquake activity in
a highly seismic region, the West Corinth rift (Central Greece), are being
studied by means of generalized statistical physics. By using a dataset that
covers the period 2001–2008, we investigate the earthquake energy
distribution and the distribution of the time intervals (interevent times)
between the successive events. As has been reported previously, these
distributions exhibit complex statistical properties and fractality. By using
detrended fluctuation analysis (DFA), a well-established method for detection
of long-range correlations in non-stationary signals, it is shown that
long-range correlations are also present in the earthquake activity. The
existence of these properties motivates us to use non-extensive statistical
physics (NESP) to investigate the statistical properties of the
frequency-magnitude and the interevent time distributions, along with other
well-known relations in seismology, such as the gamma distribution for
interevent times. The results of the analysis indicate that the statistical
properties of the earthquake activity can be successfully reproduced by means
of NESP and that the earthquake activity at the West Corinth rift is
correlated at all-time scales. |
