Seismicity monitoring by cluster analysis of moment tensors [PDF]
Geophysical Journal International, 2013 We suggest a new clustering approach to classify focal mechanisms from large moment tensor catalogues, with the purpose of automatically identify families of earthquakes with similar source geometry, recognize the orientation of most active faults, and detect temporal variations of the rupture processes.

Estimation of seismic moment tensors using variational inference machine learning [PDF]
Journal of Geophysical Research: Solid Earth, 2021 We present an approach for estimating in near real-time full moment tensors of earthquakes and their parameter uncertainties based on short time windows of recorded seismic waveform data by considering deep learning of Bayesian Neural Networks. The individual neural networks are trained on synthetic seismic waveform data and corresponding known ...

Stress-field evolution during the 26 November 2019 Durrës (Albania) earthquake sequence: Co-seismic, early post-seismic, and tectonic-region inversions [PDF]
EPJ Web of ConferencesWe resolve the stress field associated with the 26 November 2019 Mw 6.3 Durrës earthquake sequence through three windows: the co-seismic mainshock, the early post-seismic phase (mainshock plus the 36 largest aftershocks recorded between 26 November and 2

On the full-waveform inversion of seismic moment tensors
International Journal of Solids and Structures, 2020 In this work, we propose a full-waveform technique for the spatial reconstruction and characterization of (micro-) seismic events via joint source location and moment tensor inversion. The approach is formulated in the frequency domain, and it allows for the simultaneous inversion of multiple point-like events.

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 ...

Short-term seismic crustal deformation of Iran
Annals of Geophysics, 2014 In this paper the short-term seismic deformation of Iran is determined by the earthquake moment tensor summation. The study areas include the Alborz, Kopeh-Dagh, eastern Iran, Makran and Zagros orogenic belts.

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
