In April, 2016, two consecutive earthquakes registering 7 on Japanese scale occurred within 28 hours during the 2016 Kumamoto Earthquake, and caused liquefaction in many places around Kumamoto Plain. However, considering the magnitude and the distance from the hypocenter, the liquefaction-induced damage was not serious. Most of sand boiling was observed in places with higher likelihood of liquefaction such as near waterfront and on old river channels. In addition, black sand which seems to be of volcanic origin was observed as ejecta of liquefaction in many places. Therefore, cyclic triaxial tests were conducted to understand the relatively low liquefaction susceptibility on volcanic ash soil from Kumamoto by borehole sampling. Intact specimens were tested to evaluate the ageing effect in comparison with corresponding reconstituted specimens. Dissipated energy during cyclic loading was focused here as well as CRR to highlight the difference of liquefaction strength between the two kinds of specimens.
