Abstract: | A deep(H=374 km)earthquake of Mj=6.7 occurred in Kyoto-Oki region on July 16, 2007. Broad-band velocity ground motions during this event were observed at many thermal power stations in the Tokyo bay area. Waveforms observed at the stations of the east side of the Tokyo bay show longer duration than those at the west side of the bay. The apparent frequencies of later arrivals are lower than those of S-wave parts. Velocity waveforms observed in the mountain area and in the bedrock of the basin have short duration and no significant later arrivals. This suggests that the later arrivals were excited by the Kanto basin. |
