Treatment of Debris and Tsunami Deposits, and Their Effective Utilization for Restoration and Reconstruction

摘要

The Great East Japan Earthquake of March 2011 produced tsunamis that generated a great amount of debris and deposits, the appropriate treatment of which has become a major task in the reconstruction and restoration of the disaster-stricken areas. In the three stricken prefectures of Iwate, Miyagi and Fukushima, these materials exceed 22 million tons. In Iwate Prefecture, for example, it is said that the waste generated by the earthquake in a single moment is equivalent to 11 years of normal accumulation. Photos 1~3 show tsunami deposits piled in a rice field, a temporary storage site mainly for tsunami deposits, and a site for mixed waste, respectively.
