This paper deals with a method for estimation of a spatial liquefaction potential and evaluation of liquefied ground flow. This method is based on a geostatistical procedure which is called as Kriging technique using variogram. It was applied to the liquefied sites after the 1995 Hyogoken-Nambu earthquake. Horizontal ground displacements at the plane reclaimed ground that were not due to the influence of the inclination of ground surface and movement of quay wall were especially investigated here. As a result of estimation of spatial liquefaction potential, it was clarified that the magnitude and direction of liquefied ground flow were influenced by the condition of spatial spread of liquefied area such as thickness of liquefied layer and inclination of boundary between high liquefiable potential layer and others.
