This paper presents a possible way to evaluate, by geomorphological survey, the subsurface geotechnical ground conditions which may affect occurrence of liquefaction in an earthquake. Several sites where liqueaction-induced damage had occurred in the 1987 Chibaken Toho-Oki earthquake were selected and their geomorphological settings were investigated. Then, a relationship between the geomorphological conditons and subsurface geotechnical ground conditions in these phenomena was examined, and how these conditions related to the occurrernce of liquefaction was considered. Lastly, other liquefaction examples which looked similar to the 1987 earthquake in their geomorphological conditions were studied, and the usefulness of the technique to these areas was proved.
