Yokohama City has experienced many big earthquakes in the past, and local government has recently taken counter measures by using GIS. These counter measures are only calculating numerical value, which lacks time scale and many complicated relationships in human activity. In this study, we examine factors (natural, artificial, and human) in the cities that affect earthquake disaster and examine how to estimate damage in Yokohama City based on analysis of past big earthquake such as Hanshin Awaji earthquake using GIS. We examine how to do damage estimation of not only quantitative analysis but also qualitative analysis and scenario-type damage estimation.
