Microseismic moment tensor inversion based on ResNet model

open access: yesArtificial Intelligence in Geosciences
This paper proposed a moment tensor regression prediction technology based on ResNet for microseismic events. Taking the great advantages of deep networks in classification and regression tasks, it can realize the great potential of fast and accurate ...

Stable inversions for complete moment tensors [PDF]

open access: yesGeophysical 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.

Moment tensor inversion of complex earthquakes [PDF]

open access: yesGeophysical 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.

Regional Moment Tensor Inversion Using Rotational Observations

open access: yesJournal 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 ...

On the resolution of the isotropic component in moment tensor inversion [PDF]

open access: yesGeophysical 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.

Grid-Based Moment Tensor Inversion Technique by Using 3-D Green's Functions Database: A Demonstration of the 23 October 2004 Taipei Earthquake

open access: yesTerrestrial, 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 ...

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.

On the documentation, independence, and stability of widely used seismological data products

open access: yesFrontiers 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]

open access: yesJournal 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 ...

Water inrush inoculation process in mines based on moment tensor inversion

open access: yes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 ...
