Hazard and Risk in Iran

Hazard risk needs to consider vulnerability on human activities. Risk analysis of risk, human activities at spatial and temporal scales with existing classification of hazards and map hazard map. In this study hazard risk in urban areas could be useful through considering are used to model human activities such as population, land use and strategic situation in Zayandeh Rood Basin (Z.R.B), Iran. These human, activities are classified and combined with composite classified earthquake, desertification and dryness hazards maps to drive new spatially explicit five classes of composite map of the hazards and human activities. The obtained results show that there are significantly more people potentially at risk in Center and North of the basin at high classes of risk map. The proposed maps of human activities to hazards are mainly aimed at benefiting visualization and communication of hazards risk and can be valuable in all phases of the disaster management process where knowledge of human activities is relevant for decision making.
