In the 1923 Kanto earthquake of M 7.9, many wooden houses in the Yoro river area, Ichihara city, Chiba prefecture were severely demaged. The collapsed ratios of the wooden houses differed from one settlement to the other. The liquefaction of sandy sediments was major factor to the destractive damages of the wooden houses. The collapsed ratios of the wooden houses were large in correlation to the high potential of the liquefaction. The zone of burried valley of the Yoro river, which are filied with thick sandy sediments was easily liquefied to destruct seriously many wooden houses. In other areas the damages were slight because of no liquefactions. The differences of damages in each settlement were caused by the differences of the potentials of liquefaction.
