Abstract
In this study, an estimation procedure was established to assess the amount of
debris resulting from earthquake and flood disasters. Per unit generation of
earthquake disaster debris was examined on the basis of observed debris
discharge from the 1995 Great Hanshin Awaji Earthquake and the 2004 Niigata
Chuetsu Earthquake. In addition, the per unit generation of disaster debris from
flood damage above floor level was estimated at 4.6 t/household. It was shown
that this procedure would allow the amount of debris to be estimated in order
that disaster management and operation systems could be established for not
only emergency response in the aftermath, but also pre-disaster planning. In a
case study, the amount of disaster debris from earthquake and catastrophic flood
disasters in the Tokyo Metropolitan Area was estimated according to hazard
maps. It is concluded that it is important, from the viewpoint of the security of
sanitary systems in the damaged district, that disaster debris management
systems including wide-ranging cooperative measures should be established.
