Niksar (Tokat), is an urban area located in a seismically active zone of Turkey. The aim of this thesis is to prepare GIS-based microzonation map of Niksar settlement area for the purpose of urban planning. Liquefaction, activity, slope, aspect, fault proximity, ground amplification and lithology are considered during the overlay analysis by using Multicriteria Decision Making Analysis (MCDA) of Simple Additive Weighing (SAW) and Analytical Hierarchical Process (AHP) methods. Based on the evaluations, the study area is divided into four different zones, namely, (1) areas suitable for settlement / (2) provisional settlement areas / (3) areas requiring detailed geotechnical investigation / (4) unsuitable areas. Two microzonation maps obtained from analyses are compared. Maps prepared by SAW and AHP methods are found to be consistent with each other. However, the microzonation map prepared by AHP method is recommended for the purpose of urban planning because it has the ability to check consistency itself.
