Simultaneous Consideration of Seismic Tomography and Flow

到目前为止，地球三维结构的地震模拟和地幔对流的研究一直是分开进行的，后者偶尔会使用前者的后验结果。该项目的一个目标是通过对由观测到的板块速度和非静力大地水准面组成的长周期地震波形数据和地球动力学数据进行同时反演，进一步加深对地幔动力学的理解。第二个目标是进一步改进以前对地幔粘性流动的处理。同时考虑地震和地球动力学数据将有助于稳定那些分辨率较差的地理区域的地震反离子，还将使人们能够解决固体地球物理和地球动力学中的重要问题。

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.
