The earthquake hazard parameters 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 historical and instrumental periods. The technique of maximum likelihood method is applied. The procedure allows the use of either historical or instrumental data or even a combination of them. By using this method the earthquake hazard parameters, which are the maximum magnitude, Mmax, mean seismic activity rate, λ, and the b-value which is the slope of the frequency-magnitude Gutenberg-Richter relationship, are estimated. Also, probabilities (Pr) for the occurrence of earthquakes of a specified size in a each region are evaluated. According to earthquake hazards parameters computed for each region Aegean Sea, Aegean Arc and Gölhisar-Çameli, Acıgöl and Tatarlı Kumdanlı Faults and Dinar Graben have highest hazard potential.
