The territory of the Republic of Macedonia is located in the Balkan region – one of the most earthquake prone areas in Europe. Investigations of the seismicity of the Balkan Peninsula point out that this territory is exposed not only to autochthonous earthquakes but also to earthquakes from adjacent seismically active areas. The Macedonian Seismological network (SORM) and the network of the Institute of Earthquake Engineering and Engineering Seismology (IZIIS) detect, monitor and give detailed information on seismicity of the region. Their information directly impacts the accuracy of seismic hazard assessment. Application of statistical models of the “proposed future” seismic activity of the territory under investigation is of crucial importance in seismic hazard assessment. If the concept of “seismicity” indicates a measure with which natural seismic activity is determined in certain areas/sites (airports, flying fields etc.), it is of great importance in determining: 1) values of maximum expected intensity and ground accelerations of earthquakes and 2) given return periods (in years). The results of the research are presented on Seismic hazard maps for the areas with airports, airfields, and flying field sites. The parameter used as a measure of the seismic hazard for the areas under consideration, is the PGA, peak ground acceleration, (values of acceleration of g with a 64% probability to exceed).
