Earthquake is one of the natural disasters that when it happened, causes many problems and difficulties in economic, environment, human’s life, then earthquake disaster management is necessary for decreasing these problems effects and decision making in disaster condition. 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 predisaster 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 try to design different 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 farahzad (that is a part of Tehran) case study and we will discuss about results.
