INTRODUCTION: Natural hazards, especially earthquakes, have resulted in mass casualties and damages in different parts of Iran. Therefore, it is necessary to take required measures in relation to risk reduction, preparedness and coping with earthquake effects. Regarding the fact that resilience is a relatively new concept, despite the great attention to this term and its abundant application in different fields, measuring the level of earthquake resilience, as well as creating and improving it in urban settlements is a challenging necessity. METHODS: The review of literature was carried out first and the physical resilience indicators were deduced. Subsequently, a questionnaire was prepared for experts with the aim of weighting and prioritizing the indicators. Then the weight of them was calculated using the Expert Choice software and AHP (Analytic Hierarchy Process). After weighing, the indicators were prioritized. In the next step, the required information layers were prepared in accordance with the inferred indices in GIS software. After preparing the required layers and maps, a fuzzy function was used to standardize. Then, the weight of the layers was multiplied in the standardized indicators, and after calculating the layers, the final map of the physical resilience of Karaj City, Iran, against earthquake was prepared and analyzed. FINDINGS: Karaj City is one of the most vulnerable areas to earthquake due to its place located in the southern slopes of Alborz and on active faults. According to the maps prepared in this paper, large areas of Karaj City, especially in the central regions, have formed vulnerable places, which in the event of an earthquake, will have huge casualties and damages in the urban areas. CONCLUSION: It is suggested that the physical resilience of the living environment within the case study should be in accordance with the prioritization obtained in the article: 1) infrastructures, 2) buildings, 3) urban structure and 4) land use and natural factors. Also, spatial priorities should be observed in promoting urban resilience in accordance with the final map.

A growing body of research shows positive association between parks and physical activity, but very few studies have investigated the characteristics of users and how the activities vary according to different user groups. The purpose of this study was to investigate the socio-demographic profile of the users, their activities and motivation of visiting the park. Total 400 users of Ramna Park were surveyed in face to face interview in different time periods. The participants were asked to provide information about their socio-economic profile, frequency and purpose of visit, mobility and activity patterns in the park and level of satisfaction about different facilities. At a random selection of the sample, we found larger proportion of male visitors than female visitors with a majority in the age group 40-60 years. The park has a large catchment area which extends beyond the range of walking distance and the frequency of visiting the park was found closely associated with the proximity of the users. Besides, no significant association was found between the proximity and duration of staying in the park. An overwhelming majority of the visitors come to the park for health purpose mainly for walking, jogging and physical exercise. The findings suggest that the purpose of visiting the park significantly varies according to the gender and age group of the respondents. The visitors were also asked about their satisfaction level and problems they usually faced based on their individual perception. Most of them raised their concerns for poor toilet facility and waste management.
