Fig. 2From: Systematic difference between first-motion and waveform-inversion solutions for shallow offshore earthquakes due to a low-angle dipping slabVertical velocity seismograms recorded at Hi-net stations. Theoretical travel time curve assuming a hypocenter depth of 14 km (orange line) was calculated from the 1D velocity structure model of Ukawa et al. (1984). The amplitudes of each trace were multiplied by their epicentral distance. Locations of the Hi-net stations are represented by filled triangles in the right subfigure. Up and down directions are left and right in trace, respectivelyBack to article page
