Quantitative assessment of multi hazard risk (fire following earthquake) according to the method (ETA).Case: regions 1 and 6 Shiraz Municipality

Multi hazards pose a serious threat to human life. It can cause considerable damages. The evaluation of the expected losses due to multi hazards requires a risk assessment. Multi hazards risk assessment allow the identification of the most endangered areas and suggest where further detailed studies have to be carried out.
In this study, we aimed to assess the risks of multi hazard, Use of Quantitative event tree analysis in physical and human vulnerability assessment and risk mapping final (fire following earthquake). Analysis of data collected according to a combination of descriptive research and quantitative analysis. Quantitative risk assessment based on the Quantitative event tree analysis and HAZUS software. Domino effect in multi hazard vulnerability assessment based on event tree analysis. Two types of hazards will be assessed, namely earthquake, and fire following earthquake. The study estimated the direct physical vulnerability of buildings, Essential facilities And vulnerability to human (The casualties). The results show that the Study Area Most of the buildings in the study area (74%) has a low level of risk, "risk levels less than 10,000", 23.9% of the buildings in the study area has a moderate level of risk, "risk levels between 10,000 and 1,000,000" and finally (1.9%) buildings with an area of 639,660.47 square meters has a high-risk "risk levels than 1,000,000".
