When a big earthquake occurs, a large quantity of waste is generated, and local government in charge of disaster management will be overwhelmed by tasks of waste processing. Immediate estimation of the amount and kinds of wastes in an emergency plays a vital role in relief and recovery after an earthquake disaster. In this study, we collected data and records of demolished dwellings and disasters wastes and examined fectors affecting demolition rates and quantity of waste in the 1995 Hanshin-awaji earthquake. Derived empirical equations indicate that approximately 83% of dwellings heavily damaged and 15% of those moderately damaged were demolished, and that of aged dwellings tend to increase the demolition rates. The waste generation rates of timber dwellings in case of an earthquake were found more than twice compared with those in normal conditions.
