MTfit: A Bayesian Approach to Seismic Moment Tensor Inversion [PDF]

open access: yesSeismological 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.

Identification of Hydraulic Fracture Orientation from Ground Surface Using the Seismic Moment Tensor [PDF]

open access: yesGeoresursy, 2017
Microseismic monitoring from ground surface is applied in the development of hard-to-recover reserves, especially in the process of hydraulic fracturing (HF).

Seismic moment tensor event screening

open access: yesGeophysical Journal International, 2020
SUMMARY Event screening is an explosion monitoring practice that aims to identify an event as an explosion (‘screened in’) or not (‘screened out’). Confidence in event screening can be increased if multiple independent approaches are used.

Investigating Factors Influencing Moment Tensor Inversion of Induced Seismicity in Virtual IoT

open access: yesIEEE Access, 2019
The Internet of Things (IoT) for seismicity in underground mine consists of a combination of sensor network hardware and software, which allows the collection of seismic data and data processing for basic event parameters.

Moment tensor analysis of transversely isotropic shale based on the discrete element method

open access: yesInternational Journal of Mining Science and Technology, 2017
In this study, the moment tensor of transversely isotropic shale was analyzed using a discrete element method-acoustic emission model (DEM-AE model). Firstly, the failure modes of the shale obtained from the acoustic emission (AE) events and physical ...

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]

open access: yes, 2006
We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

An explosive component in a December 2020 Milan earthquake suggests outgassing of deeply recycled carbon

open access: yesCommunications Earth & Environment, 2022
A deep, magnitude 4.6 earthquake, beneath Milan, Italy, in December 2020 involved a major explosive component that may indicate outgassing of carbon dioxide from ascending carbonate-rich melts, according to moment tensor inversion of the seismic source.

Seismic moment tensors and kinematic source parameters [PDF]

open access: yesGeophysical Journal International, 1982
Summary. Parameters pertaining to the kinematics of a finite source are usually estimated by fitting specific fault models to the data. On the other hand, these parameters, including source location, are also contained in the moment tensors of higher degree.
