Understanding Micropolar Theory in the Earth Sciences II: The Seismic Moment Tensor
, 2021 Seismic events produced by block rotations about vertical axis occur in many geodynamic contexts. In this study, we show that these rotations can be accounted for using the proper theory, namely micropolar theory, and a new asymmetric moment tensor can ...

A Fast Evaluation of the Seismic Moment Tensor for Induced Seismicity
Bulletin of the Seismological Society of America, 2000 An original method is proposed for the evaluation of moment tensor components using time-domain calculations of low-frequency displacement amplitudes with the first-wave polarities attached. The technique is suitable for applications involving large amounts of data that require a fast response time, such as those encountered in the analysis of induced ...

International Journal of Mining Science and Technology, 2023 To improve the accuracy of microseismic inversion, seismic anisotropy and moment tensor source should be carefully considered in the forward modelling stage. In this study, 3D microseismic anisotropy wave forward modelling with a moment tensor source was

Cluster analysis of seismic moment tensor orientations [PDF]
Geophysical Journal International, 1993 SUMMARY This paper demonstrates that well-known methods of cluster analysis and multivariate data analysis are useful for geodynamic interpretation of seismic moment tensors. To use these methods, moment tensors are expressed as vectors in a 6-D space. These are vectors in a rigorous sense, rather than an arbitrary set of ordered numbers, because a dot
