In order to develop the design input motions for the super high-rise buildings and base-isolated buildings, we proposed a time-history prediction method of long-period ground motions, which consist of equations of acceleration spectra and phase spectra in our previous study(Satoh et al., 2010a). In this study we revise the equations and simulate the long-period ground motions of the 2011 MW9.0 Tohoku earthquake, the MW7.4 foreshock, and the MW7.8 largest aftershock. Although the revised equations are applicable to ground motions at periods between 0.1 and 10 s, the main target in this study is long-period ground motions at periods etween 1 and 10 s which are equivalent to natural periods of super high-rise buildings and base-isolated buildings. The results are summarized as follows.
