The first-order statistical moment of the seismic moment tensor [PDF]
Geophysical Journal International, 1985 Summary. If a complex earthquake is assumed to be a set of individual, randomly oriented elementary pure double couple sources, the solution for the seismic moment of the complex event projected on the mean trend of the fault will perforce be comprised of sources of both double couple and compensated linear vector dipole (CLVD) types.

Frequency‐Dependent Moment Tensors of Induced Microearthquakes [PDF]
Geophysical Research Letters, 2019 AbstractAnalysis of 984 induced microearthquakes from The Geysers geothermal reservoir in California reveals that the retrieved moment tensors depend on the frequency band of the inverted waveforms. The observed dependence is more significant for the percentages of the double‐couple, compensated linear vector dipole, and isotropic (ISO) components than

Apparent Non-Double-Couple Components as Artifacts of Moment Tensor Inversion
SeismicaCompilations of earthquake moment tensors from global and regional catalogs find pervasive non-double-couple (NDC) components with a mean deviation from a double-couple (DC) source of around 20%.

Mechanism of High Frequency Shallow Earthquake Source in Mount Soputan, North Sulawesi
Indonesian Journal on Geoscience, 2014 DOI: 10.17014/ijog.v6i3.122Moment tensor analysis had been conducted to understand the source mechanism of earthquakes in Soputan Volcano during October - November 2010 period. The record shows shallow earthquakes with frequency about 5 - 9 Hz.

Effect of sensor calibration on moment tensor analysis of granite uniaxial compression
Rock and Soil Mechanics, 2021 Moment tensor inversion theory is an effective method to study the rock failure mechanism. However, the inversion results are prone to large errors, which can mislead the understanding of fracture mechanism.

Moment tensor decompositions revisited [PDF]
Journal of Seismology, 2014 The decomposition of moment tensors into isotropic (ISO), double-couple (DC) and compensated linear vector dipole (CLVD) components is a tool for classifying and physically interpreting seismic sources. Since an increasing quantity and quality of seismic data allow inverting for accurate moment tensors and interpreting details of the source process, an
