This project will develop a suite of geophysical techniques that will improve capabilities to integrate quantitatively the results of seismic and geodynamic modeling. The aproach - called geodynamic tomography - is a new form of constraint tomography that differs from those previously implemented. Geodynamic models will be mapped into their seismic signature and anisotropic tomography will be used to formally test the model against the seismic data. This method will limit the search for acceptable seismic models to a subset that are consistent with geodynamic predictions, and will allow rigorous testing of the differing geodynamic assumptions against actual observations.

该项目将开发一套地球物理技术，以提高定量整合地震和地球动力学建模结果的能力。这种方法被称为地球动力学层析成像，是一种新的约束层析成像形式，与以前实现的方法不同。地球动力学模型将被映射到它们的地震特征中，各向异性层析成像将用于根据地震数据正式测试模型。这种方法将可接受的地震模型的搜索限制在与地球动力学预测一致的子集中，并将允许根据实际观测对不同的地球动力学假设进行严格的测试。
