| Zusammenfassung |
| The time dynamics of seismicity of Aswan area (Egypt) from 2004 to 2010 was
investigated by means of the (i) Allan Factor, which is a powerful tool
allowing the capture of time-clusterized properties of temporal point
processes; and the (ii) detrended fluctuation analysis, which is capable of
detecting scaling in nonstationary time series. The analysis was performed
varying the depth and the magnitude thresholds. The 2004–2010 Aswan
seismicity is characterized by significant three-fold time-clustering
behaviors with scaling exponents ~0.77 for timescales between
104.16 s and 105.14 s, ~0.34 for timescales between
105.14 s and 106.53 s, and ~1 for higher timescales. The
seismic interevent times and distances are characterized by persistent
temporal fluctuations for most of the magnitude and depth thresholds. |
