Abstract

The amount of flammable materials in traditional Japanese houses in the Hiroshima region in the 1940s is estimated to calculate heat, water and carbon fluxes during the induced urban fire by the Hiroshima A-bomb in 1945. Traditional houses remaining in the Fukuyama region were examined to estimate the total amount of flammable resources in each house classified into three categories based on number of stories and size of the houses. Our research revealed that the kind of flammable resources is mostly pine and the density of wood was estimated to be 112 kg m-2 for one-story houses while it was 72 kg m-2 for two-story houses.
