| Zusammenfassung |
| In order to estimate the hazard rate distribution of the largest
seismic events in Vrancea, South-Eastern Carpathians, we study
temporal properties of historical and instrumental catalogues of
seismicity. First, on the basis of Generalized Extreme Value theory
we estimate the average return period of the largest events. Then,
following Bak et al. (2002) and Corral (2005a), we study scaling
properties of recurrence times between earthquakes in appropriate
spatial volumes. We come to the conclusion that the seismicity is
temporally clustered, and that the distribution of recurrence times
is significantly different from a Poisson process even for times
largely exceeding corresponding periods of foreshock and aftershock
activity. Modeling the recurrence times by a gamma distributed
variable, we finally estimate hazard rates with respect to the time
elapsed from the last large earthquake. |
