A study of the spatial distribution of seismicity parameters is undertaken along Turkey and its vicinity, using the Gumbel's third asymptotic distribution of extreme values (GIII). The data set used spans of 111 years (1900-2010). The seismicity of the whole region is subdivided into equal area mesh of 1A degrees lat. x 1A degrees long. Various seismicity parameters examined, resulted from the application of the GIII method. The results show a quite good correlation between the seismicity parameters and the tectonic regime of the studied area. For instance high values concentrated around North Anatolian Fault. The x (2)-test is applied throughout the whole process and in every stage of GIII, in order to check the accuracy of the obtained results. The spatial distribution of upper-bound (omega) formed a W-shape pattern, which shows the difference in the mechanical structure of the materials in the examined area.
