The aim of this research was to analyze the earthquake hazard of the East Macedonian seismic zone by determining the a and b values in Gutenberg-Richter law. For this purpose, the previously known division of the zone to six epicentral areas was used. The b and a values were calculated for the epicentral areas where the seismic data permits, using the least square method. Using these values, the mean return period, the most probable maximum magnitude in t year time period and the probability for an earthquake occurrence with magnitude ≥M within time span of t years were estimated. Furthermore, maps with spatial variations of the parameters will be provided.
