Abstract
We evaluated tsunami damage reduction performance in Sendai Plain in case of the Great East Japan Earthquake using the relationship between building damage level and coastal forest width. Coastal forest width is defined as the width of the coastal forest area existing on a straight line to the nearest shoreline from each building. In order to discuss about the relationship, distance from the coastline and building damage level for each structure type of buildings were calculated. As results, the damage level of the wooden buildings having wide coastal forest width was found to be smaller in comparison to those having narrow width. In addition, when the influence of the distance from the building to the shoreline and the elevation of the buildings were not considered, there is a correlation between the reduction effect of coastal forest width and the damage level of the building.
