Zone 6 of Tehran, with a populations of 220,000 people (3.6 per cent of the city population) and 20 km2 area (3 per cent of the city area), is one of the main municipal zones of Tehran. Major land-uses, like ministries, embassies, universities, general hospitals and medical centers, big financial firms, and so on, manifest the high importance of this region on a local and national scale. Thus, it is necessary to pay close attention to issues concerning crisis management in this area.

In this paper, by using indexes such as access to medical centers, street inclusion, building and population density, land-use, peak ground acceleration and building quality, vulnerability degree of street networks in zone 6 against the earthquake is calculated through overlaying maps and data in combination with inversion hierarchical weight process method and geographic information systems.

This article concludes that buildings alongside the streets with high population and building density, low building quality, far to rescue centers and high level of inclusion represent high rate of vulnerability, compared with other buildings. Also, by moving from north to south of the zone, the vulnerability increases. Likewise, highways and streets with substantial width and low building and population density hold little values of vulnerability. Thus, streets with high level of inclusion, building and population density present further vulnerability.

It is expected that the results of this paper be used by the urban decision-makers. Due to high vulnerability of most parts of the urban textures of Tehran, similar researches will have importance for preparation for the future possible earthquakes.

The purpose of this paper is to identify the vulnerable factors in the neighborhood and vulnerability assessment of residential, medical center, school buildings, the road networks and the green spaces as vital and critical land uses to get general estimation of the situation for risk reduction planning.

Seismic vulnerability assessment of buildings was performed using the rapid visual screening data collection form of FEMA P 154 (2015). The assessment of the road was carried out using an empirical model, and the condition of the green spaces was assessed complying with standards using GIS.

The results of research indicated that about 37 percent of selected residential buildings, 81.08 percent of schools and two health care centers are likely to be vulnerable to earthquake.

Based on the results of this study, many of the structures should be further evaluated. Strengthening of poor-resistant elements of the roads is recommended and must be in order. Although the green spaces are well distributed in the neighborhood, they are ill-equipped of necessary facilities and their development is also recommended.
