| Zusammenfassung |
| The historical and instrumental catalog of the Absheron-Prebalkhan region in
the Caspian Sea area was analyzed in order to reveal the existence of
temporal clustering in the time dynamics of the seismicity. The timespan of
the catalog is from 1842 to 2012 and the magnitude of the events ranges from
2.5 to 6.8. The Gutenberg-Richter analysis indicates 4.0 as the completeness
magnitude of the catalog. The temporal clustering analysis was performed
over the sequence of events with magnitude M ≥ 4 by using the methods of
the Allan Factor and the coefficient of variation. Both the methods have
revealed the presence of time-clusterized structures in the time dynamics of
large events in the Absheron-Prebalkhan region. Such findings, which suggest
a non-Poissonian behavior of the seismicity of the investigated area, could
contribute to a deeper knowledge of the time dynamics of the seismicity and
to a better assessment of the relative seismic hazard. |
