Spatial Modeling for Reducing Earthquake Disaster Damages in Iran

Earthquake is one of disaster that when happened causes many problems in economic and society in Iran, so earthquake disaster management is necessary for decreasing these problem effects. Because of most related data with earthquake and its effects have spatial properties, so GIS can be used as effective tool for managing and decision making in disaster. In some countries such as Iran, disaster experiences show that managing and decision making before occurring earthquake is more effective than doing some activities after occurring earthquake, therefore pre-disaster phases in the disaster management cycle is much more important. Purpose of second phase of disaster management cycle that is called mitigation is planning for creating a resistance urban against earthquake. In this study, we designed and implemented two efficient models for entering earthquake zoning rules in urban planning using GIS modeling tools. At first we will define problem structure, then we introduce different models using for earthquake zoning, finally we implement these models on the FRAHZAD (that is a part of Tehran) case study and we will discuss about results.
