Depth variation of Green’s functions for pure strike- and pure dip slip moment tensors. Three-component displacement waveforms for the a pure strike-slip (M xy  = 1.0) and b pure dip slip (M zz  = − M xx  = 1.0) sources. A band-pass filter with passed periods of 30–100 s was applied into each trace recorded at F-net station N.ABUF. Red, blue, and black traces are Green’s functions derived from the JIVSM (Koketsu et al. 2012), sJIVSM (JIVSM without an accretionary prism and seawater), and F-net 1D velocity structure model (Kubo et al. 2002), respectively
