Abstract :In this study, liquefaction susceptibility maps of the Saruhanlı district of Manisa insert ignore into journalissuearticles values(Turkey); were prepared based  on different methods for the evaluation of liquefaction potential and various liquefaction indices. Three main  fault zones are present near the study area, namely Bergama, Buyuk Menderes, and Gediz Graben. The Gediz  Graben controls the seismicity of the area. The total length of this fault zone is about 150 km, and it is about 33  km from the study site. By considering historical earthquakes within the Gediz Graben and its length, a design  earthquake with a moment magnitude of 7.1 was selected for the study site. A peak ground acceleration of  0.28g was calculated for the study site using attenuation relationships developed for Turkey. In order to analyze  liquefaction susceptibility of the Saruhanlı region, results from a total of 28 cone penetration tests insert ignore into journalissuearticles values(CPT);  were  evaluated. Four different CPT-based methods were used for the calculation of factor of safety against  liquefaction. These factors of safety were used to define the liquefaction indices. Three different liquefaction  indices were used to develop the liquefaction susceptibility maps of the area. Hence, a total of twelve  liquefaction susceptibility maps were prepared to evaluate liquefaction potential of the area. In additon,liquefaction susceptibility maps were prepared using varying depths of the ground water table to determine the  effect of seasonal ground water level changes on the liquefaction severity. Besides, liquefaction-induced ground  settlement maps were also prepared for the study site.  Key words: Liquefaction, liquefaction susceptibility maps, liquefaction index, CPT, Saruhanlı.
