This paper describes the damages of buildings caused by liquefaction of ground on the Niigata Earthquake, 1964. In the first place, we examined the investigated data which we surveyed immediately after the Earthquake and recently. Then we assumed the damage rate of wooden or RC buildings. As a result, it is found that in the large damaged area, 57% RC building got larger damages and the damage rate of wooden buildings was 40.7%. Further, it is assumed that in the liquefied area, the earthquake acceleration was lower, and the damages showed some peculiarity. From these points of view, it is found that in case of assuming the earthquake danger of area, we need not overlap the danger by earthquake vibration and liquefaction of ground.
