Analytical models of volcanic ellipsoidal expansion sources
Annals of Geophysics, 2013 Modeling non-double-couple earthquakes and surficial deformation in volcanic and geothermal areas usually involves expansion sources. Given an ensemble of ellipsoidal or tensile expansion sources and double-couple ones, it is straightforward to obtain ...

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 ...

Annals of Geophysics, 2008 The seismic sequence that hit Umbria and Marche during 1997 and 1998 was particularly significant because it dramatically marked the evolution of analysis tools and the development of our geophysical knowledge of the region. Since September 1997, we have

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.

Monte Carlo approximate tensor moment simulations [PDF]
Numerical Linear Algebra with Applications, 2014 SummaryAn algorithm to generate samples with approximate first‐order, second‐order, third‐order, and fourth‐order moments is presented by extending the Cholesky matrix decomposition to a Cholesky tensor decomposition of an arbitrary order. The tensor decomposition of the first‐order, second‐order, third‐order, and fourth‐order objective moments ...

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 ...

SciPost Physics, 2022 We consistently couple simple continuum field theories with fracton excitations to curved spacetime backgrounds. We consider homogeneous and isotropic fracton field theories, with a conserved $U(1)$ charge and dipole moment.

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 ...

Physics Letters B, 2016 In this letter, we examine a new class of CPT-even nonminimal interactions, between fermions and photons, deprived of higher order derivatives, that yields electric dipole moment (EDM) and magnetic dipole moment (MDM) in the context of the Dirac equation.

Laboratory Investigation of Hydraulic Fracture Behavior of Unconventional Reservoir Rocks
Geosciences, 2021 The heterogeneity of the rock fabric is a significant factor influencing the initiation and propagation of a hydraulic fracture (HF). This paper presents a laboratory study of HF created in six shale-like core samples provided by RITEK LLC collected from
