It is important to predict a damage risk in an area due to gusty winds in order to make disaster measures of local government and to calculate a rate of a nonlife insurance premium. In this paper, we tried to predict a damaged area of buildings using building densities and the high wind damage scale by the tornado that occurred in Nobeoka, Miyazaki in 2006. Then we compared the actual building damage and the predicted one. Since there were many non-damaged building in an area where smaller wind blew, actual occurrence rate of damage building was not coincident with probability density used to predict. Therefore, large damaged area of buildings was predicted in an area where building damage hardly occurred in reality. However, the predicted building damage and the actual one corresponded in an area where stronger winds blew.
