Integrated Earthquake Fire Risk Evaluation Based on Single Building Fire Probability Applicable to All Map Scales

Abstract

It is difficult to create a fire risk evaluation method that is applicable to different map scales from a single building to the whole region of Japan. Conventional simulation methods use city indices or mesh-data, but in the proposed method the fire destruction probability of each single building can be calculated. Thus the method reflects the actual spatial characteristics of a city and can be used for general purposes with no margin of error. It is possible to rearrange the results in different area units and to obtain the numbers of burned out houses and areas. In addition, the method provides appropriate information for conveying the fire risk to the public by showing them cluster data of the simulation. This cluster data is sometimes referred to as the Fatalistic Collaboration Community Unit.
