The damage to wooden houses caused by the 2001 Geiyo earthquake was surveyed at residential districts arround the western part of Hiroshima City; Koi-ue in Nishi-Ward,and Ajinadai in Hatukaichi City. Extensive damage of roof-tiles of wooden houses occurred on the fill ground more than the cut ground in an improved land. In this study,the assessment method is developed for classification of ground between fill and cut using 3-Dimensional Geographic Information Systems (3-D GIS) technique. TIN (Triangulated Irregular Network) and Overlay tools are employed against old and new 3-D geographical surfaces of residential districts in order to make classification of ground between fill and cut. Subsequently,the depth of fill or cut is calculated from cross-sectional information for 3-D surfaces. It is found that the depth of fill,where the damage of roof-tiles of wooden houses occurred,ranges between 5 to 15 meters.
