Teleseismic Response of Kinematic Earthquake Source Models in General Elastic Media

9614698朗斯顿这项研究使用了来自全球地震局和世界地震局的现有远震数据集，以研究三维非均质性和层状各向异性对远震波形的影响。一般来说，地震发生在地质有趣的地区，具有明显的构造不均一性证据。有证据表明，近源非均质性可以对地震辐射的远震波产生重大影响，这些影响将映射到反演源参数，如断层滑动的空间/时间分布和震源方向。根据文献中详细的地质和地球物理研究，将对提出的构造模型的近源效应的频率依赖性进行理论研究。然后，将使用正演计算和反演技术对观测到的地震的远震数据进行建模，以确定震源参数并确定非均质性和各向异性的影响。***

9614698 Langston This research involves the use of existing teleseismic data sets from the GSN and WWSSN to investigate the effect of 3D heterogeneity and layered anisotropy on teleseismic waveforms. Earthquakes, as a rule, occur in geologically interesting areas with clear evidence of structural heterogeneity. There is evidence that near-source heterogeneity can have significant effects on radiated teleseismic waves form earthquakes and that these effects will map back into inverted source parameters such as the spatial/temporal distribution of fault slip and source orientation. The frequency dependence of the near-source effect will be investigated theoretically for proposed structure models constrained by detailed geological and geophysical studies in the literature. The teleseismic data from observed earthquakes will then be modeled using forward calculation and inversion techniques to determine source parameters and to determine the influence of heterogeneity and anisotropy. ***
