Moment tensor inversions and dipping slabs
Geophysical Research Letters, 1982 Moment tensor inversions were performed on synthetic teleseismic P and SH body wave data for two plausible orientations of intermediate depth earthquakes located in a slab. A ray method was used to generate the synthetic P and SH data for dipping slab models.

Moment Tensor Inversions of Icequakes on Gornergletscher, Switzerland [PDF]
Bulletin of the Seismological Society of America, 2009 We have determined seismic source mechanisms for shallow and intermediate-depth icequake clusters recorded on the glacier Gornergletscher, Switzerland, during the summers of 2004 and 2006. The selected seismic events are part of a large data set of over 80,000 seismic events acquired with a dense seismic network deployed in order to study the yearly ...

Moment tensor inversions and source models [PDF]
Geophysical Journal International, 1978 Summary. The use of a moment tensor formulation in source mechanism inversions is becoming more widespread. However, this method does not yield results that correspond to a double-couple source, which is still the preferred source model. This is because the double couple is characterized by extra constraints on the general symmetric moment tensor.

Source parameters of the M 6.5 Skyros Island (North Aegean Sea) earthquake of July 26, 2001
Annals of Geophysics, 2002 Teleseismic body wave modelling, time domain moment tensor inversion of regional waveforms and spectral analysis of the far-field P-wave pulses are used to derive the source parameters of the July 26, 2001 Skyros earthquake (M 6.5).

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.
