To investigate the safety of structures for future mega-thrust earthquakes, it is important to develop a reliable source model for the simulation of strong ground motions from such earthquakes. Nozu et al. (2012) developed a source model called the “SPGA model” for the purpose of simulating strong ground motions from mega-thrust earthquakes in the frequency range relevant to structural damage. It is, however, necessary to further investigate the reliability of the source model especially by using records from dense strong-motion arrays such as the Small-Titan. In this article, the SPGA model is applied to the records of the Small-Titan and its performance is discussed.
