The definitions of the risk factors due to a possible earthquake on the settlement area are useful for decreasing hazard of a potential earthquake and essential for preparing the management plans by the local municipalities and government. Soil amplification, vulnerability of buildings, natural period of soils and liquefaction are the main risk factors of a possible earthquake. On the other hand, before definitions of these risk factors, the distribution of the soil classes should be determined. By the way, the determination of the method of the soil classes in 3D is the main purpose of this study.
