Internal fault homes in Marvdasht and its surroundings, experience of these faults, return period of earthquakes and SEISMIC hazard zonation in the old texture, extent, type and amount of burnout, and high possibility of destruction is the most important threats for this city. Materials and Methods in this research is descriptive / analytical and it is practical based on the goal. The instrument used in this study is questionnaire, observation and interviews with residents and use of books and articles.
