Investigation of seismicity of Antalya city metropolitan area [Antalya İli Yerleşim Alani{dotless}ni{dotless}n Depremselliǧinin Araşti{dotless}ri{dotless}lmasi{dotless}]

Population of antalya is growing rapidly due to internal immigration. moreover,millions of tourists are visiting antalya every year. antalya city center lies in the second degree earthquake zone of turkey. western part of antalya,where seismic activity is more intense,lies in the first and second degree zones. taking into account the poor construction quality and the weak ground conditions,seismicity of antalya becomes point of interest. in this study,to investigate the seismicity of antalya city center,a seismic hazard analysis was carried out considering earthquakes occurred between 1900 - 2010 in the seismotectonic zones around antalya,using statistical techniques. antalya city center is located in the central part of isparta angle and affected by earthquakes which are the products of components of this tectonic structure. a parameters lie in the range between 5.61 - 6.77,and b parameters in 0.86 - 1.06 for the seismotectonic zones around antalya. for a circle having radius of 100 km and the centre is located in antalya city center,probability of occurrence of an earthquake having magnitude 5 or more is 71 %. it is understood that probability of an earthquake having magnitude 6.5 or more is 15 % in 50 years. applying attenuation relationships,the greatest horizontal ground acceleration is estimated as 0.1g. for soft soils it is obvious that this value will reach a higher value due to ground amplification. it is clear that in a different study,magnification and liquefaction studies should be studied for the weak soils. before starting an investigation for safety of buildings against earthquake,a micro-zonation study related to dynamic behaviour of all the antalya soils should be completed.
