Abstract
Large-scale earthquakes are often accompanied by simultaneous multiple fires. In addition to the collapse of buildings due to the earthquake, inundation by the tsunami, etc., it is necessary for local governments and residents to understand the risks of fires properly. It helps not only the initial fire fighting and evacuation by residents in case of fires, but also the town planning against disasters and actions by fire stations.
Although the spreading fire analysis can be used for the risk assessment in earthquake fires, there is a limit in analyzing a large area collectively due to the memory of computers and calculation time.
In this study, the method dividing the target area into blocks and integrating the results of each block is proposed in the spreading analysis of using the electronic residential map. It is applied to the risk assessment of the earthquake fire.
