| Research Abstract |
We obtained seismic velocity structure model under the Japanese Island using waveform inversion technique up to depth 2000km and the precision of about 20 seconds. To calculate synthetic seismograms, we used Spectral-Element Method. The obtained model shows different spatial distribution for P-wave and S-wave structure respectively, which may imply that the velocity structure is derived from different origins.
