An example of a pair of tsunami waveforms observed at an offshore wave station and its nearby coastal tidal station. Tsunami waveforms observed at the NOWPHAS wave station (off Tomakomai harbor), which is located 4.0 km from the nearest coast, and the tide gauge at west Tomakomai harbor (no. 2 in Fig. 1 and Table 1) during the 2003 Tokachi-oki earthquake tsunami (D in Fig. 1 and Table 2) are indicated. Tsunami waveform data (Nagai and Ogawa, 2004) have been downloaded from http://www.pari.go.jp/bsh/ky-skb/ kaisho/.
