Setting regional division of Shizuoka prefecture based on database of natural disasters

In order for effective damage prevention, it is necessary to have some idea of when, where, why and what kind of natural disasters may strike, and how large they may be. In this study, I made a database which can be use for GIS to facilitate multivariate analysis of presently available data for Shizuoka prefecture. This analysis can map out likely natural disaster locations and causes. Using the result of this analysis for GIS, a regional range of the disaster categorized by factors can be shown and analyzed visually and easily updated when a disaster occurs in the future.
