Liquefaction is one of the most damaging phenomena and its importance has motivated research. Various method have been recommended by investigators to analyze liquefation potential, each of which may be used depending on the quantifiable data and geological conditions. In this study, the liquefation potential of a foundation soil in the city of Bandar Tokaman, situated in Soithestern part of the Caspian Sea (Golestan Province, Iran) was studied using multiple methods. The geological conditions and soil deposition state were assesses in this region and the influence of geological condition on liquefaction potential was investigated as well. The obtained results show a relatively close correlation between the liquefaction potential and standard penetration test results, relative density and Atterberg limits. Futhermore, the Casagrande test, which is used for the determination of fine-grained soil liquid limits, displayed to some extent, dynamic soil behavior. There is also very close relationship between a soil's Liquid Limit (LL)and the factor of safety derived from the cyclic stress ratio.Fanally, from a theoretical point of view, it is possible that soil may criteria for possible liquefation, but it can be influenced by different interrelated geological factors.
