Microseismic Monitoring at the Farnsworth CO2-EOR Field
Energies, 2023 The Farnsworth Unit in northern Texas is a field site for studying geologic carbon storage during enhanced oil recovery (EOR) using CO2. Microseismic monitoring is essential for risk assessment by detecting fluid leakage and fractures.

Regional Moment Tensor Inversion Using Rotational Observations
Journal of Geophysical Research: Solid Earth, 2020 Abstract Abstract There are benefits from the addition of rotational motions to translational displacements for moment tensor (MT) inversions. The rotational radiation pattern is orthogonal to the shear radiation pattern, thus incorporating rotations is equivalent to ...

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.

On the resolution of the isotropic component in moment tensor inversion [PDF]
Geophysical Journal International, 1997 SUMMARY It is in theory possible to solve a full moment tensor from inversion of a few seismograms, using normal-mode data, surface waves or body waves. In fact, the isotropic component is usually set to zero in many inversions, in order to stabilize them.

Water inrush inoculation process in mines based on moment tensor inversion
工程科学学报, 2015 To achieve the effective monitoring of rock failure events in the mine water inrush inoculation process, a moment tensor inversion method based on digital seismology was introduced to process abnormal microseismic events monitored in Hebei Fanshan ...

On the documentation, independence, and stability of widely used seismological data products
Frontiers in Earth Science, 2022 Earthquake scientists have traditionally relied on relatively small data sets recorded on small numbers of instruments. With advances in both instrumentation and computational resources, the big-data era, including an established norm of open data ...

Source type plot for inversion of the moment tensor [PDF]
Journal of Geophysical Research: Solid Earth, 1989 Seismic signals provide information about the underlying moment tensor which, in turn, may be interpreted in terms of source mechanism. This paper is concerned with a two‐dimensional graphical display of all possible relative sizes of the three principal moments; it provides a method of representing the probability density of these relative sizes ...

Communications 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.

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.
