Figure 2From: Guided wave observations and evidence for the low-velocity subducting crust beneath Hokkaido, northern JapanThree-component seismograms (a) and particle orbits of the X phase (b). The station (N.SAMH) and the earthquake are shown in Figure 1b. Seismograms are band-pass-filtered (1 to 12 Hz). Black circles denote the theoretical time of P and S waves. The red inverted triangle indicates the arrival of the X phase.Back to article page
