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.
The spreading fire analysis can be used for the evaluation of the earthquake fire risk, but careful attention should be paid to the generalization of the analysis results which changes greatly depending on the conditions such as allocated fire origins.
In this study, a new earthquake fire risk assessment index is proposed considering the spreading time of fires, by conducting the spreading fire analysis with all the buildings as fire origins in the target area.
