| Zusammenfassung |
| Probabilistic Seismic Hazard Assessment (PSHA) has traditionally been based on time-independent earthquake occurrence rate. However, the Dead Sea fault zone (DSFZ) is an area, where the cumulative number of large earthquakes (with Mw>=6) shows two high and low activity periods. This indicates not only a time dependency of the earthquake occurrence rate but a temporal cyclic change in behaviour of the occurrence rate in the long term (so-called long-term temporal clustering behaviour). In this study statistical methods have been suggested to test the time-dependency as well as the multimodality (temporal clustering behaviour) of the earthquake occurrence rate and then to find the best statistical distribution to fit the earthquake inter-event times and occurrence rates respectively. The methods have been applied to the large earthquakes (with Mw>=6) along the DSFZ. |
