The scale length of heterogeneities revealed by seismic waves, not including the laboratory measurements of rock samples, spans 8 orders of magnitude. These heterogeneities with different scales have different effects to seismic waves. The velocity and density heterogeneities can cause the change in waveform, phase or travel-time and amplitude fluctuation, as well as apparent attenuation of the direct arrivals. They can also generate coda waves such as the P-coda, S-coda, and Lg-coda caused by the lithospheric heterogeneities and precursory waves such as the scattered PKP waves as the precursors to PKIKP caused by the heterogeneities near the core-mantle boundary.

The near-source or near-receiver structures can modify the seismic waveforms by resonance and other effect. Rough topography or rough interface can cause the coupling between body wave and surface wave. Aligned cracks in the crust can produce the effective anisotrophy.

A great complexity arises when heterogeneities have interaction with anisotrophy and nonlinearity. Unable to display preview. The purpose of this proposal is to harness these new found capabilities to enhance the quality of models of Earth's interior, in conjunction with improving models of the rupture process during an earthquake. On the face of it, this seems like a Herculean task because hundreds or even thousands of model parameters are involved in such inversions.

1st Edition

In principle, the sensitivity of a seismogram with respect to the model parameters may be calculated numerically, but this would require a number of forward calculations equal to the number of model parameters typically thousands. By drawing connections between seismic tomography, adjoint methods popular in climate and ocean dynamics, and time-reversal imaging, we have demonstrated that one iteration in tomographic and source inversions may be performed based upon just two calculations for each earthquake: one calculation for the current model and a second, adjoint, calculation that uses time-reversed signals at the receivers as simultaneous, fictitious sources.

This has finally opened the door to solving the full 3D inverse problem, i. We have demonstrated how this may be accomplished in 2D, and one of the main goals of this proposal is to extend these capabilities to fully 3D inverse problems. Broader impacts of the project include continuing the development of code that is useful to the seismic community and the support and training of a graduate student and a postdoc.
