We have reviewed liquefaction-induced damage to reclaimed ground, levees and industrial complexes, caused by the 2011 off the Pacific Coast of Tohoku Earthquake. Then, we reconsidered the method of the prediction of liquefaction and estimated liquefaction at Urayasu housing area using a new liquefaction prediction method based on dynamic numerical liquefaction analysis of the ground. We also clarified the feature of the damage of levee due to the 2011 Great Tohoku Earthquake based on the dynamic liquefaction analysis and listed the lessons taught by the analyses and the damages due to the 2011 Tohoku Great Earthquake are shown.
