Regional Variation of the w-Upper Bound Magnitude of GIII Distribution in the Different Regions of Western Anatolia

The expected maximum magnitudes are estimated for different regions of the Western Anatolian (WA). The whole examined area is divided into 15 seismic regions based on their seismotectonic regime. The database used in this work was taken from different sources and catalogues such as TURKNET, International Seismological Centre (ISC), Incorporated Research Institutions for Seismology (IRIS) and The Scientific and Technological Research Council of Turkey (TUBITAK) for instrumental periods. The technique of Gumbel-III method is applied. By using this method an upper bound to the magnitudes (ω) is estimated. Also, we compared ω and M_max from Kijko-Sellevol method to research any relation between these parameters. We can say that these parameters are clearly relation each other and reflect expected maximum magnitude for 15 source regions in WA. According to ω and M_max computed for each region Aegean Sea, Aegean Arc, Sultandağı and Tatarlı-Kumdanlı Faults and Dinar Graben have highest hazard potential.
