Severe water disaster was occurred again in the Shodoshima Island on 8〜13th September 1976. 39 peoples were killed and more than 400 houses were badly damaged. As reported by IKEDA and others (1977), such a disaster had been occurred about two years before it, in the eastern part of the island. The calamity was brought on the people mainly by the attacks of debris flows caused by falls of mass of grus from the mountains. It is noteworthy that not few of the falls of grus were closely related with human agency. For example, many falls happened from the road which lead to the second-house quarters "Villa Shodoshima" and grew into debris flows that attacked the houses. In another case, many shallow-type landslides were occurred on the mountains burnt out in a fire 8 years before the disaster. As was stressed by IKEDA and others (1977), fundamental and the most serious problem is the recent increase of houses and development of residental quarters. Nowadays, many peoples live unavoidably on dangerous places such as active alluvial fan, foot of steep slope of deeply weathered mountains, etc. In Kobe city, water disaster, caused by similar circumstances of dwelling, already occurred in 1938. Such disasters might increase still more in Japan.
