| Outline of Final Research Achievements |
The purpose of this project was to extend the deterministic tomography and establish the stochastic tomography using seismic waveforms. By such stochastic tomography, we can expect to resolve chemical heterogeneities that have not been well resolved by previous deterministic approaches. We developed an appropriate Monte-Carlo method to invert seismogram envelopes. Using our method and up-to-date broadband OBS (ocean bottom seismology) data, we succeeded to show the possibility that we can directly show the strong heterogeneities in the lithosphere and the strong internal attenuation in the asthenosphere. Our results should open the new way of future seismological analysis.
