were damaged.
This paper investigates the characteristics of the house damage and the
recovery process in Nagasaki prefecture, by both field survey and questionnaire,
and also topographic features and the direction of the house damage, its
type of roof tile, environ's topographic features and the direction of
the wind. Finally, some suggestions are made for the reduction of house
