A Study on Relationship between the Impact of Earthquake Disaster to the Movement of Population , 'Commercial and Industrial Activities' and the Character of District

Abstract

The purpose of this study is the production of a knowledge for preparedness of recovery and reconstruction measures.In this case study of the 1995 Great Hanshin-Awaji Earthquake, we estimated the degree of social/economic damage such as the decrease of population, amount of sales, number of shops and factories, manufacturing products and so on after the earthquake by 18 municipal regions that were damaged severely. Additiionally we analysed the relationship between those damages and characteristics of local economy and society. As a result, the degree of population decrease is related closely to houses damage ratio, owner-occupied house ratio and low-income ratio.The damage of manufacturing is also related to damage ratio of buildings, but not to productivity. The damage of retail is related to the decrease of population as regional consumers.
