Always crises, natural and unnatural disasters have threatened the urban life and have led to cities destruction. But many cities shortly after these crises have been able to return to their ordinary life. This return can be called as resistance. Increasing in resistance of the cities against the natural disasters, especially earthquake is effective in reduction of losses and also in the recovery period of the societies. The plan makers and administers the cities, as the most important entities involved in designing the cities, have a key role in increasing the resistance of urban communities against earthquake. Physical resistance is one of the effective aspects of resistance of societies, through which the physical and geographical characteristics of the cities in disasters can be evaluated. This study is a practical, descriptive and analytic study and aims to identify the indicators and factors affecting physical resistance and to quantify and compare the physical resistance sub-criteria in old areas of Bushehr. The population of this study is the residents in old areas of Shanbadi, Aliabad, Mahkboland, and etc. 381 questionnaires consist of general and specific questions, using Liker scale, were handed out among the residents of these areas. The reliability, using Cranach’s alpha, was evaluated for analysis of physical resistance in old areas, ANOVA and T-test have been applied to divide the areas according to physical indicators. In order to obtain the required map in these areas, GIS software was used. Finally, physical resistance indicators (e.g. access, quality of buildings, the access before the earthquake, infrastructural resistance, earthquake, resistance) using multi comparison T-test were studied. The results show that the neighborhoods in these areas are different in terms of their physical resistance indicators.
