Abstract :Turkey is located in a highly seismic region, where Mw > 6.5 earthquakes take place in every 10 year. According to the seismic zonation map of Turkey, approximately 42 % of the Turkish territory is located in the most seismic prone zone, known as Zone I. The other seismic zones are termed as Zone II, III and IV from the second severe to the least severe one. In this paper, we investigated the seismicity of Adana Province that is situated on four different seismic zones insert ignore into journalissuearticles values(i.e. Zone I to IV);. Accordingly, we developed probabilistic seismic hazard maps of Adana for 475 year return period for stiff and soft site conditions. The probabilistic seismic hazard maps are presented in terms of PGA. The comparative maps indicate remarkable differences between proposed PGA values and the current design PGA values provided by the seismic zonation map and Turkish Earthquake Code
