A sand sample erupted by liquefaction is one of the keys to estimate the grain size distribution of liquefiable soils. When the sampling of erupted sand is appropriately performed, the erupted sand can provide substantial information on liquefied layers. Moreover, since such a sample is easily obtainable from the liquefied site, reasonable evaluation of the liquefiable grain size distribution based on a large number of samples is possible. In this study, using 823 samples obtained from liquefied sites due to 13 earthquakes, the following aspects were examined: 1) the difference in grain size distribution between samples taken from young aged grounds (e. g., reclaimed lands), and samples taken from grounds composed mainly of Holocene deposits; 2) the properties of grain size distributions of the erupted sands; and 3) comparison with the conventional criteria of grain size distribution of liquefiable soil. It was found that there exist finer limits in the grain size distribution of liquefiable soils for young aged ground and Holocene deposits, respectively.
