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.

Gas slug ascent through changes in conduit diameter : Laboratory insights into a volcano-seismic source process in low-viscosity magmas. [PDF]
, 2006 Seismic signals generated during the flow and degassing of low-viscosity magmas include long-period (LP) and very-long-period (VLP) events, whose sources are often attributed to dynamic fluid processes within the conduit.We present the results of ...

Science of Remote Sensing, 2022 We propose a procedure based on remote sensing Sentinel-1 InSAR data aiming at evaluating the variability of the moment tensor solutions provided by different agencies in case of light-to-moderate earthquake.

Seismic moment tensor event screening
Geophysical 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
IEEE 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
International 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 ...

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.

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]
, 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 ...
