Abstract :

Earthquake is a natural phenomenon that neglecting it will lead to irreparable damages. The occurrence of severe earthquakes has prompted mankind to think of developing an infrastructure plan to reduce the risks and damages caused by it. The purpose of this research is to investigate the damages caused by the earthquake in the area of ​​two cities of Yazd using the radius model in the GIS environment in the proposed scenarios. Based on this and according to the radius model, the factors of the number of building floors, type of soil, type of materials, existing faults, land use and existing vital arteries were used. that the effective factors of using separate layers were investigated in ArcGIS 10 software and the required information of the radius model was extracted and entered into the radius model to achieve the results. The results of the research show that according to the Mehriz-Teft fault scenario, 1577 buildings will be destroyed, 7 people will be killed and 243 people will be injured. According to the Anar fault scenario, 1108 buildings will be destroyed, 4 people will be killed and 132 people will be injured.
