By the response analysis of soil layers with regard to fault rupture model, seismic ground motions in about 300 mesh areas in Nagoya city were estimated for three earthquakes: the Nobi earthquake of 1891, the Tonankai earthquake of 1944 and the Mikawa earthquake of 1945. On the other hand, damage ratios to wooden houses in each mesh area due to these earthquakes were obtained by rearranging original data. From the comparison of seismic ground motions to damage ratios in each mesh area, it was found that maximum acceleration at the ground surface was the major factor of earthquake damage and ground liquefaction which occurred in the ground consisting of loose sandy deposits even in rather low acceleration level was another damage factor. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
