| Abstract: | A liquefaction potential map of a wide area is very useful for evaluating risk of liquefaction for the dwelling houses. In this study, the liquefaction potential map is developed by overlaying three maps including a PGV（Peak Ground Velocity）map, a liquefaction map from the past earthquakes and a land classification map. The damage ratio of the dwelling houses are evaluated as a production of three results which are the liquefaction susceptibility by the PGV at the ground surface and the ratio of liquefaction area in grid cells of 30 arc-seconds latitude ×45 arc-seconds longitude and the damage ratio of the dwelling houses in a liquefaction area from the past earthquakes. The prediction of this evaluation procedure shows a good agreement with the damage ratio of the dwelling houses for the 1987 Chiba-ken Toho-oki Earthquake. |
