Estimation Method of Amount of Tsunami Disaster Wastes during the 2011 off the Pacific Coast of Tohoku Earthquake

Abstract

A huge amount of disaster wastes was accumulated along coastline areas of the Tohoku region by tsunami during the 2011 off the Pacific coast of Tohoku Earthquake. It is very important to estimate amount of tsunami disaster wastes as for quick recover and revival of damaged areas. This paper describes a method of wastes amount estimation based on the officially published data analyzed in GIS platform. As a result of this study, it was found that there is a well relationship between the amount of disaster wastes and submerged area, population, tsunami height and so on, and that the number of damaged buildings within the submerged area using GIS software (Arc Map) has high accuracy in comparison with the published data
