Map of target region. Source regions of the M 8-class Nankai and Tonankai earthquakes are overlapped with the depth contours of the oceanic water layer. Numbered line shows the linear site array that was used for the simulations in this study. Source regions and asperities of the Nankai and Tonankai earthquakes are simplified from the source model by the Central Disaster Prevention Council of Cabinet Office (see, for example, Tsurugi et al., 2005). Osaka, Kobe, Kyoto and Nagoya cities located in the disaster area are also shown for reference.
