WebMay 30, 2024 · The study of teleseismic tomography needs an important premise that the velocity inhomogeneity of the lower mantle is that the seismic wave has enough small amplitude and long wavelength. When the condition is satisfied, the wave front of the seismic wave incident in the study area has a small curvature [ 15 ]. WebThe teleseismic events ( M ≥ 6.0) used are located in a distance range of ~30° to 90° from central Japan ( Fig. 2B ). Many of the local events occurred in the subducting Pacific slab close to the middle portion of the slab (>25-km depth below the slab surface; Fig. 2A ), which can notably improve the tomographic resolution in the Pacific slab.
