Information about liquefied and not-liquefied sites during past earthquakes is useful for liquefaction potential mapping of wide area. Therefore, inquiry of liquefaction-induced ground failures during the Kanto earthquake was performed for preparing a liquefaction potential map in Tokyo lowland. Interviews with above 300 persons who had experienced the hazard in Tokyo lowland were carried out. Historic liquefaction-induced ground failures are determined from these narratives and the reports concerning the earthquake. Liquefied sites distribute along the rivers and old river beds, and in reclaimed lands. Not-liquefied sites distribute away from the coast or rivers. Liquefied grounds along the rivers consist of sandy deposits containing only a small amount of fines, and the grounds containing considerably fines hardly liquefied. However, the sandy deposits containing fines were prone to liquefaction in reclaimed lands.
