Abstract

The aim of this research is to clarify the correlative relationship between natural condition and the tsunami and earthquake disaster, and how the target area develops in relation with the natural condition by creating a map which illustrates the units of natural sites. As a result of analysis, three outcomes were clarified. First, correlation with the units of natural sites was observed with respect to land use change. Also, settlements onto specific units of natural sites, which are not suitable for settlements, had incurred more severe damage during the disaster. Second, natural site units were classified depending on the situation of the tsunami and earthquake disaster. Third, natural site units provide a better way to reconstruct settlements against earthquake-tsunami disaster as an urban planning technique and a sustainable way for regional structure.
