Moment tensor inversion of complex earthquakes [PDF]
Geophysical Journal International, 1982 Summary. Moment tensor inversion methods can be applied with success in the determination of source properties of simple earthquakes. However, these methods utilize the assumption of a point source, which is inadequate for modelling many complicated, shallow earthquakes.

MTfit: A Bayesian Approach to Seismic Moment Tensor Inversion [PDF]
Seismological Research Letters, 2018 MTfit is a Python module for Bayesian moment tensor source inversion of earthquake seismic data using polarities, amplitudes, or amplitude ratios. It can solve for double‐couple or full moment tensor solutions, taking into account uncertainties in polarities, takeoff angles of the rays from the source to the receiver, and amplitudes.

Microseismic moment-tensor inversion
, 2011 It is common practice in the oil and gas industry to use a single vertical well with limited number of geophones to monitor the microseismicity induced by hydraulic fracture treatment. In this thesis, I have employed a synthetic and stochastic modeling approach to investigate the effects of monitoring geometry and noise on inverting recorded P- and S ...

Moment-tensor inversion and decomposition for cracks in thin plates
Chinese Journal of Aeronautics, 2021 Abstract The knowledge of crack type and dislocation orientation is helpful for the lifetime prediction of thin plates on aircrafts. The moment-tensor inversion utilizes the Acoustic Emission (AE) signals to detect cracks and the source mechanisms can be interpreted by the decomposition of moment tensors. Since the traditional moment-tensor inversion

Grid-Based Moment Tensor Inversion Technique by Using 3-D Green's Functions Database: A Demonstration of the 23 October 2004 Taipei Earthquake [PDF]
Terrestrial, Atmospheric and Oceanic Sciences, 2010 Moment tensor inversion is a routine procedure to obtain information on an earthquake source for moment magnitude and focal mechanism. However, the inversion quality is usually controlled by factors such as knowledge of an earthquake location and the ...

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.

Stable inversions for complete moment tensors [PDF]
Geophysical Journal International, 2008 SUMMARY The seismic moment tensors for certain types of sources, such as volcanic earthquakes and nuclear explosions are expected to contain an isotropic component. Some earlier efforts to calculate the isotropic component of these sources are flawed due to an error in the method of Jost & Herrmann.

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
