Abstract

earthquakes  is considered as  one of the most destructive  and threating factor for demolition  of human- environment life in the world and its resulting damages in different dimensions (physical, social and …) affect on the urban societies which are the most modern and volunerable settlement pattern in the world.
But this natural phenomenon itself at any place may not have the   potential for  creating crisis and  damage  .  But the readiness and careful  planning for determining  the degree of damage, control and decreasing the undesireable consequences of earthquake can determine its crisis degree. Therefore, knowing and recognition of physical and social dimensions of this subject which has a bilateral relationship in the damages resulting from earth quake will be necessary.
The considered study with "development - applied" nature and  "descriptive - analytical" research method  has reviwed this issue in Yazd city and since the only tool of human for determining the resulting damages is the available information and statistical-quantitative methods, therefore this study has evaluated and zoned seismic damages by using 30 variables of social-physical indices and using VIKOR technique and GIS, as well as Excel and SPSS softwares.
The results showed that VIKOR value or in other words value of Qi, Si and Ri, in three regions of Yazd are  (Qi=990.0, 001.0, 79.0), (Si=775.0, 246.0, 676.0) , (Ri=184.0, 151.0, 176.0) respectively and  Based on VIKOR model provisions ,district No. 2 in three groups of R,S and Q is placed at the  lowest rank; Then at the next phase, district No.3 and finally No.1 has the least volunerability  in Yazd city.
