Abstract
Earthquakes can lead to different levels of
damages and subsequently produce significant volume of
debris. Management of such huge amount of debris needs
special attention. Thus, it is vital to develop a comprehensive
and cost-effective management plan. The present
study was carried out to estimate post-earthquake debris
volume in the 22 districts of Tehran under various earthquake
scenarios [magnitudes of 5, 6.5, and 7.5 on the
moment magnitude (MW) scale]. Subsequently, required
machineries and manpower and equipment for removal of
debris were calculated. Finally, best practical methods for
reduction and recycling were also examined. The shortest
routes for transportation of post-earthquake to disposal
sites were also proposed using network analysis. Results
showed that about 83, 321 and 4802 million cubic meters
of debris will be generated at 5, 6.5 and 7.5 MW, respectively.
Disposal site of about 13 km2 is marked within the
area of study for the management of debris. Preparedness,
emergency operations, rehabilitation and reconstruction are
among the main activities that can reduce the earthquakeinduced
damages.
