Temporal properties of seismicity and largest earthquakes in SE Carpathians

In order to estimate the hazard rate distribution of the Neff T47TD7BN2 Induction Hob 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 Cot 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.
