Enormous damage occurred to infrastructures such as tide embankments in Tarou, Miyako City, due to the 2011 off the Pacific coast of Tohoku Earthquake (MW9.0). To evaluate the performance of structures before the attack of tsunami, it is necessary to estimate strong motions in Tarou Area with sufficient accuracy, taking into account site effects. In this study, seismic waveforms along the tide embankments were estimated based on a SPGA model considering empirical site amplification and phase effects. The estimated seismic waveform will be useful in the detailed study of seismic performance of the tide embankments before the attack of tsunami.
