Abstract
With the relative value of the quantity of disaster waste calculated by the estimated debris and the amount of garbage total exhaust in annual, the disaster response capacity of public authorities in the huge earthquake disasters was estimated. A numerical simulation model for wide-area cooperative measures in the emergency debris operation was developed. The required period for emergency debris operation with wide-area cooperation by the backyard method on earthquake disaster in the Tokyo Metropolitan area was estimated at 21.6 months. In addition, it was indicated that the required period for debris operation in the huge earthquake disasters was influenced by the wide-area cooperative measures.
