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，提高地震和地球动力学模拟结果定量综合的能力。 该方法-称为地球动力学层析成像-是一种新形式的约束层析成像，不同于以前实施的。 将把地球动力学模型映射到其地震特征中，并将使用各向异性层析成像法对照地震数据对模型进行正式测试。 这一方法将把寻找可接受的地震模型的范围限制在与地球动力学预测一致的一个子集内，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。
