In part 1, we certified that it is useful to use aerial photos to investigate damage distribution of houses hit by a storm. In the former report, we induced regression equation, which can approximately estimate a damage ratio of the houses hit by a storm, by means of multiple regression analysis with combination of some topographical factors. Then we made clear the effects of every factor with residual analysis of which manner was to analyse the discrepancy of real damages and evaluated results. From the results, we found out that so long as to discuss the effects of topographical factors on damages of houses hit by a storm, there were some particular points which may be influenced by more local factors, such as hill, slope, foot of mountain. Those were too difficult to incorporate into the analysis numericaly. Thus, in this paper, we analysed the effects of every topographical factor by means of the combination of regression equation deviced from both quantification analysis and residual analysis. Where, quantification analysis is the method to be able to analyse the effects of every factor without estimate them numerically. By this way, we found out that it is necessary to take account of more limited factors than we chose in our former paper. In conclusion, we proposed a new manner to analyse the relationships between topographical factors and damages of houses hit by a storm.
