| Zusammenfassung |
| The time dynamics of the aftershock sequence of the Al-Hoceima (Morocco)
earthquake of 24 February 2004 has been investigated. The sequence of the
occurrence times of the events with threshold magnitude Mth≥3.2 is
characterized by a time-clustering behavior, identified using different
fractal methods (Fano Factor, Allan Factor, Count-based Periodogram), well
suited to reveal scaling features in point processes. The obtained results
not only show the presence of memory phenomena and correlation structures in
the Al-Hoceima aftershocks, but also furnish quantitatively the estimate of
the magnitude of such correlation by means of the estimate of the scaling
exponent α. |
