Earthquake is one of the most dangerous, destructive and unpredictable natural hazards. Therefore, identify the vulnerable areas of cities is necessary in order to increase the capacity to deal with earthquake risks and crisis management of this risk. In this regard, the present study was written with the aim of investigating the vulnerable levels of Tabriz metropolis against earthquakes and providing crisis management solutions (before the crisis) to reduce the effects of earthquakes. The research method in the current study is mixed (combination of qualitative and quantitative approaches) with a practical purpose and analytical-exploratory nature, in order to analyze information; FAHP method in ArcGIS and PROMETHEE method were used. In addition, the statistical population of the research includes managers, city officials, and academic elites. The sample size of managers and officials was determined using Cohen's method at the 95% confidence level, 90 people, and the method of accessing them is based on the snowball method. The size of the sample of academic elites is also determined based on the targeted Delphi sampling method of 14 people. The findings of the research show that the peripheral and central areas of the city have the highest vulnerability potential. Meanwhile, regions 10 and 1 with net flow of -0.454 and -0.527 are considered among the areas with high vulnerability to earthquakes. Among the factors affecting the vulnerability of these areas, we can mention the proximity to the fault, wear and tear of the tissues, distance from the aid centers, high density and the lack of elasticity of the roads. For this purpose, a systemic and integrated approach is needed in order to be able to recover and empower the community, and in this regard, it is necessary to pay attention to the pre-crisis stage in the dimensions of building retrofitting, improving access and

Introduction The concept of a livable city means to be suitable for living or habitable, which has been very strong today by expanding and intensifying the problems human societies and the loose of quality of life. The phrase "livable cities" was used for the first time in 1970 by the national Arts organization to achieve their urban ideas and looking for it by other centers and research organizations such as the environmental protection organizations that has done extensive studies regarding the most of American cities was gone. Following the influence of this word in the literature related to this field can be searched in 1975 and the writings of William Marlins on the fields of livable in Saturday Review and Christian Science Monitor. In recent years, research and development in the area of sustainable cities has attracted much attention. The continued growth of urbanization with social, economic, physical, and environmental problems is creating a crisis leading to metropolitan instability, which in turn reduces the viability of metropolises. According to the standards, Tabriz's livelihoods were at a low level, and lack of proper planning would make it a city in the not too distant future where it would be difficult to live. Therefore, the necessity and importance of biodiversity debate in the Tabriz metropolis is increasing. In addition, given that Iranian cities are currently suffering from a lack of attention to existing urban contexts. In this regard, the present study aimed to evaluate the viability of Tabriz urban texture. This article is based on scientific study and tries to answer the following questions. In terms of the subjective dimension of living (objectively satisfied residents) what is the status of Tabriz urban context? Data and Method This research is applied in nature and is descriptive-analytical in terms of method. The measurement tool in this study was a questionnaire developed based on the subjective-psychological dimension of living (objective satisfaction of residents). The statistical population of the study is based on the empirical view of urban environment quality assessment, the inhabitants of old and new urban texture based on Morgan table number of 1558693 people according to the size of community and according to Morgan table is 384 people, Classified by sampling and assigned appropriately to each of the low-lying, semi-rich and rich neighborhoods respectively, 39, 70 and 42 (old tissue samples) and 100, 71 and 62 (new tissue samples), respectively given. Multivariate analysis of variance (MANOVA) was used to analyze the data. Multivariate analysis of variance is the extension of variance analysis to situations in which there is more than one dependent variable. Results and Discussion What exactly is more socially viable, according to Winnewon? It's not completely clear, and people are happier and more satisfied in communities where their needs are better met. In this regard, due to the lack of attention to urban texture biodiversity and the increasing expansion of urbanization, upgrading the viability of Tabriz metropolitan area requires an examination of the status of urban tissues; And provide the basis for new urban development, insights, and cognition on the nature of Tabriz metropolitan urban biodiversity that identifies priorities for action to make these tissues viable in the decision environment. The results of the present study show that the overall life expectancy in Tabriz textures was below average, while the analysis of the current status of Tabriz's biodiversity in different dimensions shows that the average is generally achieved. In all aspects (urban services and infrastructure, urban environment, urban economy, urban management, urban history, and urban community), the findings were lower than average, and this is consistent with the findings of Rashidi et al (1395) who have estimated the biodiversity of Tabriz metropolitan area in comparison with Osco, Azarshahr, Bostanabad, Tabriz, Shabestar and Harris. This finding indicates that this metropolis will in the future be governed by the same current practice and managers and citizens will be not reinforce the deficiencies in the status queue, in the future the city will never move towards sustainability and sustainable development. According to the assessment made between the old and new textures of Tabriz metropolis, there is a significant difference in the viability. The results showed that the old tissue viability was higher than the new tissue based on the results due to the higher average ratings of services and urban infrastructure, urban community, urban history, urban economy, and urban management in the old tissue neighborhoods; This finding is in line with the findings of Dalir et al (1388) based on indicators of access to educational, health, daily shopping centers, weekly shopping malls, green spaces, recreational and sports centers, downtown and public transport to measure people's satisfaction with the new context Low level of evaluation, alignment. Conclusion The findings also indicate that in order to sustain the new texture, urban community, and urban management indices that have a significant difference with the old texture should be given more attention by city officials and managers. And in order to make old tissue more viable then the urban environment, which is less ranked than new tissue, must be taken into consideration by urban managers, so that proper planning for resource allocation and viability in these tissues should be emphasized. At the core of the indicators are the lower levels, so that by utilizing the available forces and potentials to achieve a comprehensive development that will bring prosperity and prosperity to all citizens.

Introduction The concept of a livable city means to be suitable for living or habitable, which has been very strong today by expanding and intensifying the problems human societies and the loose of quality of life. The word "livable cities" for the first time in 1970 by the national Arts organization in order to achieve their urban ideas and looking for it by other centers and research organizations such as the environmental protection organizations that has done extensive studies regarding the most of American cities was gone. Following the influence of this word in the literature related to this field can be searched in 1975 and the writings of William Marlins on the fields of livable in Saturday Review and Christian Science Monitor. Today, by expanding the problems of human societies and increasing their day to day (problems) has been greatly increased the quality of life indicators of residents of different places. Tabriz is one of the oldest cities in the country with regard to the historical, economic, cultural, health and industrial backgrounds of Tabriz metropolis, which has turned the city in to the first city in different fields. Today not only does not upgrade this roles and functions but also is in annihilation state. Because of its complex and multi-dimensional conceptual and its patterns vary from one region to another. So far a comprehensive model of the impact of the overall livability of cities on the present situation and the relationship between them is not defined. This paper tries to measure the present situation based on the appropriate models of Tabriz and the effect of the dimensions of livability on the situation in objective models based on scientific methods. Hence, the main objective of the present study was to determine the level of livability indices based on their impact on the situation in Tabriz metropolis using structural equation modeling technique. The output of this research helps urban managers and planners have a bright picture of the ecological sector of Tabriz metropolis. This article has been formulated based on scientific study and tracking to answer the following question. What conditions is the current condition of the city of Tabriz in different dimensions? and which indicators should be the first priority of the planners be given the amount of their impact on the present situation to achieve urban livability in Tabriz metropolis? Methodology This research is applied in terms of nature and is a descriptive-analytic method. The instrument was a questionnaire the statistical population in this research are the experts and urban managers with complete familiarity with the situation of each region, has a number of 140 people. According to the volume of society and Morgan table, 104 people selected by non-linear snow bullets and the question have taken place. Then the statues of livability using single sample T-Test and relationship between dimensions and livability in dices is analyzed with structural equation modeling whit Partial least squares method(PLS). Results and discussion Due to the increasing development of the life- level of Tabriz metropolis, requiring the main indicators and influence on the existing situation and communication between them. This research has provided new insight in to the livability of Tabriz metropolis that will detect the priorities of action in the decision space. Study of analysis of the present analyses regarding the current situation of Tabriz's livability in different dimensions generally, the average obtained in all dimensions (urban services and infrastructure, urban environment, urban economics, urban management, urban history and the urban community) were lower than the average and the results are not statistically significant only for urban community index that the results of this indicator are not generalized. Also, prioritizing indicators due to their impact on the present situation to achieve urban livability in Tabriz metropolis shows that highest share of urban services and infrastructure are (providing daily necessities in the neighborhoods, highways access, access to other neighborhoods in the city, access to workplace, the quality of water, electricity, gas and internet, Bank, quality of public transportation in neighborhoods, public transport work hours and distribution of public transport stations), that pays attention to urban managers and planners. Research findings show the current condition of Tabriz's livable situation according to the average of all ten areas in all dimensions is low that it has alignment with the findings of Rashidi and colleagues (1395) who have assessed the livability of Tabriz region in comparison with the Osku, Azarshahr, Bostan Abad, Tabriz, Shabestar and Herris. This findings with the findings of Ali Akbari and Akbari (1396), which has recognized the equitable distribution of facilities and services identified the main livability of the city of Tehran, the study of Aluria (2017) that the factors affecting on the quality of life of residents has expressed the distribution of urban services and also the ministry of Sustainable Management in India (2018) that physical index (with 45%) highest ranking in the livability standards. Conclusion This research, based on structural equations analysis shows that the services and urban infrastructure have the highest effect on the present situation of Tabriz metropolis livability In any attempt to improve the livability of Tabriz, it should be considered the role and position of this indicator. The results show that all aspects of livability in Tabriz metropolis have low average. The results of the model also show that among the influence factors on livability status, "urban infrastructure and services" and "urban environment", "urban management", "urban history" and "urban community" factors have a direct and meaning full effect, In the meantime, the "urban infrastructure and services" factor has the greatest impact which has a motivation of Tabriz metropolis livability. As a result, any program and attempt to initiate and upgrade of the livability of Tabriz status need attention to the key role of these factors. But what is particularly the achievement of the present study is preparation of appropriate bio-model with the new scientific methodology Partial least squares (PLS) based on present conditions.
