Abstract. This paper proposes a new model in evaluating seismic microzonation of ground shaking by considering direct characteristics of influencing criteria and dealing with uncertainty of modelling through production of fuzzy membership functions for each criterion. The relevant criteria were explored by reviewing previous literature and interviewing 10 specialized experts. Analytic Hierarchy Process (AHP) and Fuzzy Logic (FL) methods were applied in order to define priority rank of each criteria and to fuzzify sub-criteria of each criterion by interviewing 10 experts, respectively. Applying Fuzzy Logic method to deal with uncertainties of sub criteria of each criterion and using direct characteristics of each criterion are the new approaches in designing a new model. The criteria and sub-criteria were combined in GIS to develop a model for assessing microzonation of ground shaking in the study area of Bam city, Iran. The model’s output shows high to very high ground shaking levels were happened in central, east, and northeast to north part of the area. The validation results based on overall accuracy and Kappa statistics showed 80 % to 82 % accuracy, 0.74 and 0.75 Kappa indicating a good fit to the model's output. This model assists planners and decision makers to produce seismic microzonation of ground shaking to be incorporated in designing new development plans of urban and rural areas, and to facilitate making informed decision regarding safety measures of existing buildings and infrastructures. Keywords: Seismic Microzonation, Site Effects, Ground Shaking, Spatial Modelling, Analytic Hierarchy Process, Fuzzy Logic and GIS.

Short summary
This paper proposes a new model in evaluating seismic microzonation of ground shaking by considering direct characteristics of influencing criteria and dealing with uncertainty of modelling through production of fuzzy membership functions and GIS. This model assists planners and decision makers to easily produce seismic microzonation of ground shaking to be incorporated in designing development plans of urban areas, and to evaluate safety measures of existing infrastructure.
