Fig. 8From: Effects of subsurface structures of source regions on long-period ground motions observed in the Tokyo Bay area, JapanParticle motion from velocity seismograms at station TKY003 during the 2011 event. The three bottom rows indicate the particle motions in the radial vertical (UD) plane, transverse vertical (UD) plane, and transverse radial horizontal plane. The particle motions are displayed every 10 s. Red circles and crosses indicate the start and end points, respectively. The three top figures are velocity traces in the transverse, radial, and UD components, respectivelyBack to article page
