(records from the K_NET and KiK-net strong-motion networks) to study the spatial correlationfor peak ground acceleration and pseudo-spectral acceleration at different periods from 0.1 secto 5.0 sec. Sokolov et al. [29] analysed characteristics of ground motion correlation using thedatabase accumulated in Taiwan. The results reported by these studies reveal different rates ofdecay of the correlation with separation distance. It has been shown that the differences relateto the frequency content of ground motion [25, 30]. On the other hand, the differences may becaused by regional peculiarities [28, 29]. Table 1 summarises the data used and the obtainedresults of some of the studies; Figure 1 shows several models of spatial correlation.ReferenceWang andTakada [11]Goda andHong [25]Sokolov etal.
