The earthquake, directivity of the energy released, distance of rupture from The magnitude of the earthquake, focal point and depth of The MERM (2003) microzonation manual sets different criteriaĪffecting the amplitude and duration of ground shaking at a specific site. Uncertainty of modelling through production of fuzzy membership functions ofĮach criterion. This paper explores direct characteristics of influencing criteria inĮvaluating susceptibility of local seismic amplification and deals with This model assists planners and decision makers in determining local seismic amplification susceptibility to be incorporated in designing new development plans of urban and rural areas and in making informed decisions regarding safety measures of existing buildings and infrastructures. The validation results based on overall accuracy and kappa statistics showed 73.6 % accuracy, with 0.74 kappa indicating a good fit to the model's output. The model's output demonstrated high to very high seismic amplification levels in central, eastern, northeastern, and northern parts of the study area. The criteria and sub-criteria were combined using the weighted linear combination method in GIS to develop a model for assessing local seismic amplification susceptibility in the study area of Bam City, Iran. Two methods, analytic hierarchy process (AHP) and fuzzy logic (FL), were applied in order to define priority rank of each criterion and sub-criteria of each criterion through interview data of 10 experts.
