Development and implementation of a GIS-based tool for spatial modeling of seismic vulnerability of Tehran

Abstract

Abstract. Achieving sustainable development in countries prone to earthquakes is possible with taking effective measures to reduce vulnerability to earthquakes. In this context, damage assessment of hypothetical earthquakes and planning for disaster management are important issues. Having a computer tool capable of estimating structural and human losses from earthquakes in a specific region may facilitate the decision-making process before and during disasters. Interoperability of this tool with wide-spread spatial analysis frameworks will expedite the data transferring process. In this study, the earthquake damage assessment (EDA) software tool is developed as an embedded extension within a GIS (geographic information system) environment for the city of Tehran, Iran. This GIS-based extension provides users with a familiar environment to estimate and observe the probable damages and fatalities of a deterministic earthquake scenario. The productivity of this tool is later demonstrated for southern Karoon parish, Region 10, Tehran. Three case studies for three active faults in the area and a comparison of the results with other research substantiated the reliability of this tool for additional earthquake scenarios.

Seismic vulnerability assessment of school buildings in Tehran city based on AHP and GIS

“…Rashed and Weeks, 2003;Maithani and Sokhi, 2004;Servi, 2004;Gulati, 2006;Thapaliya, 2006;Cole et al, 2008;Nath and Thingbaijam, 2009). Therefore, many Iranian researchers such as Zahraie and Ershad (2005), Aghataher et al (2008), Amini Hosseini et al (2009), Hataminejad et al (2009) and Hashemi and Alesheikh (2012) have identified the effective factors in earthquake hazard assessment and applied various methods in developing a seismic hazard map. Among these studies, identification and reduction of the seismic vulnerability of school buildings against earthquakes is essential since, according to the Standard 2800 (BHRC: Building and Housing Research Center, 2005), school buildings are among the most vital structures, with their upgrading against earthquake being highly important for the reduction in loss of life as well as properties.…”

Physical Seismic Vulnerability Assessment of Tehran Using The Integration of Granular Computing and Interval Dempster- Shafer

“…The main cause of earthquakes in Tehran is the existence of faults such as Northern Tehran, Ray, Mosha, and Kahrizak in the Tehran Metropolitan Area (TMA) (JICA, 2000). In addition, high population, rapid urban expansion, and the existence of some non-standard buildings, have made Tehran vulnerable to earthquakes Delavar, 2011, Hashemi andAlesheikh, 2012). This seismic vulnerability may result in great human and financial losses.…”

A hybrid model for mapping simplified seismic response via a GIS-metamodel approach

“…Therefore, Geographic Information Systems (GIS) contribute the most to maximizing the available data in assessing or estimating ground-motion amplification (Kolat et al, 2006;Ganapathy, 2011;Hashemi and Alesheikh, 2012;Turk et al, 2012;Hassanzadeh et al, 2013) as well as seismicinduced effects (Grelle et al, 2011;Grelle and Guadagno, 2013). In this regard, the literature suggests approaches based on either experimental geophysical methods, such as dynamic low-strain (linear) measurements, mainly from ambient noise, or numerical simulation methods of linear or non-linear stress-strain response during shear-wave propagation in the layered cover.…”
