The Western Tottori earthquake (M=7.3) caused extensive dwelling damage and human casualty in the disaster area. Approximately 1600 dwellings and other structures were demolished and left local governments difficult task of processing disaster wastes. In this study, we collected data and records of demolished dwellings and disasters wastes for 8 cities and towns from Tottori prefectural government and examined factors affecting demolition and quantity of waste. The results indicate that the ratio of dwelling demolition is roost affected by heavy damage ratio, that more wood and incombustible wastes were produced by dwellings than by storage houses, and that unit quantity of waste per area (m^2) is greater than those reported for normal conditions and for the 1995 Hanshin-awaji earthquake.
