Simultaneous Consideration of Seismic Tomography and Flow

到目前为止，三维地球的地震模拟 进行了结构和地幔对流的研究 分别，后者偶尔雇用，后验， 前者的结果。 该项目的一个目标是 通过表演进一步加深对地幔动力学的理解 长周期地震波形数据的同时反演， 地球动力学数据，包括观测到的板块速度， 非静力大地水准面 第二个目标是进一步完善 地幔中粘性流的先前处理。 的 同时考虑地震和地球动力学数据将有助于 以稳定那些地理区域的地震反演， 解决得很差，它也将允许一个解决重要的 固体地球物理学和地球动力学的问题。

Until now, seismic Modelling of three dimensional Earth structure and the study of mantle convection have been performed separately, with the latter occasionally employing, a posteriori, the results of the former. One objective of this project is to further advance understanding of mantle dynamics by performing simultaneous inversions of long-period seismic waveform data and geodynamic data consisting of the observed plate velocities and nonhydrostatic geoid. The second objective is to further refine previous treatments of viscous flow in the mantle. The simultaneous consideration of seismic and geodynamic data will help to stabilize the seismic inverions in those geographical areas that are poorly resolved and it will also allow one to address important issues in solid-Earth physics and geodyamics.
