Abstract
The effect of fault distance on human casualty caused by earthquake was
clarified. In this paper, we treated 7 inland type earthquakes and 1 oceanic
type earthquake which had occurred before 1950 in Japan. The data of housing
damage were classified to different ranks. Under certain rank of housing
damage, the effect of fault distance on human casualty was investigated
with the method of statistical tests of significance. The result of this
study shows that the ratio of human casualty at nearer area to the seismic
source was heigher than that in far away. We consider that the difference
of human casualty rate is related with the difference of collapse mode
of houses.
