Liquefaction-induced lateral spreading during Tohoku earthquake resulted in significant damage, and disruption of functionality\r\nfor structures and life. The paper aims at reproducing this on-site evidence presenting the state of the art about the most credited\r\nqualitative approach and comparing these methods with numerical computation. In this regard, finite element (FE) simulations are\r\nincreasingly providing a versatile environment in order to assess economical and effective damage. In the study, several systematic\r\nthree-dimensional FE computations have been conducted to numerically evaluate the effects in terms of liquefaction-induced lateral\r\ndeformations. The analysis is performed in correspondence with Urayasu City, where the registered liquefaction consequences on\r\nresidential buildings were wide if compared with the ordinary seismic shake. This study can be used both for post-earthquake\r\nevaluations and for pre-earthquake vulnerability predictions.
