Abstract
This study aims to estimate potential disaster waste generation using statistical and web information. In particular, we focused on the disaster waste derived from household durable goods.
Firstly, we built a database of the mass per unit of the major durable consumer goods. Using the mass per unit database, the national average of the number and mass of durable consumer goods in a household were calculated based on the items found in the average household as reported in the National Survey of Family Income and Expenditure. The results of calculations based on the national average was about 1.5 to 2.5 tonne.
Secondly, the number of durable consumer goods in households in the communities expected to be damaged by a Nankai earthquake were multiplied by the number of completely destroyed buildings, and by the type of damage (such as the size of the earthquake and tsunami) as provided by the Cabinet Office and local authorities, to estimate the amount of disaster waste generated in each community. As a result of the estimation, if we used the Central Disaster Prevention Council's figures in which the Kinki region is simulated to be severely damaged, Shizuoka Prefecture was likely to have the largest amount of disaster waste, at about 630 to 1,020 thousand tonne.
