Fig. 4From: Effects of subsurface structures of source regions on long-period ground motions observed in the Tokyo Bay area, JapanVelocity response spectra with 5% damping for the Tokyo Bay area stations. b Show the spectra from the 2011 event. a Show those from the 2014 event. Red, green, and blue lines indicate the spectra for the NS, EW, and UD components, respectively. Characters in each frame indicate the station code. The location of each station is shown in Fig. 2 Back to article page
