Relative moment tensors and deep Yakutat seismicity [PDF]
Geophysical Journal International, 2019 SUMMARYWe introduce a new relative moment tensor (MT) inversion method for clusters of nearby earthquakes. The method extends previous work by introducing constraints from S-waves that do not require modal decomposition and by employing principal component analysis to produce robust estimates of excitation.

Matched filtering for the seismic moment tensor
Geophysical Research Letters, 1976 By a process of matched filtering it is possible to deconvolve a small number of acceleration or strain records for the moment rate tensor of a seismic source. Theoretically, one horizontal accelerometer (or strain meter) or two vertical accelerometers is sufficient. Practically, five to ten records can be shown to suffice.

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 Abstract We present an approach for rapidly estimating 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 (BNNs).

Anomalous stress diffusion in earthquake triggering: Correlation length, time dependence, and directionality [PDF]
, 2003 It has been recently suggested that moderate and large earthquakes can be triggered by similarly sized events at very long range. Here we study the main characteristics of earthquake triggering by determining its correlation length, time dependence, and ...

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.
