In this paper, the response of a liquefiable site during the 1995 Kobe earthquake is studied using vertical array records, with particular attention on the effects of nonlinear soil behavior and liquefaction on the characteristics of ground motions. The characteristics of ground motions during shaking events are analyzed first. A fully coupled, inelastic finite element analysis is thereafter performed to simulate the earthquake response of the array site. The stress-strain histories of soils
