Mathematical modeling of wave fields in layered media with additional stresses

open access: yesГеофизический журнал, 2012
We consider the model of a vertically inhomogeneous medium, when one or more layers are under more stress. We analyzed the results of research of influence of hydrostatic pressure act-ing in one of the layers of horizontally-layered structure of the wave

GPU-acceleration 3D rotated-staggered-grid solutions to microseismic anisotropic wave equation with moment tensor implementation

open access: yesInternational Journal of Mining Science and Technology, 2023
To improve the accuracy of microseismic inversion, seismic anisotropy and moment tensor source should be carefully considered in the forward modelling stage. In this study, 3D microseismic anisotropy wave forward modelling with a moment tensor source was

Seismic structure and earthquake focal mechanisms of the Hengill volcanic complex, S W Iceland [PDF]

open access: yes, 1996
Iceland provides a unique opportunity to study the processes that occur along mid- ocean ridges. In 1991, thirty temporary seismic stations were installed at the Hengill volcanic complex to record high-quality digital data from local earthquakes.

English teachers' journeys since the 2020 Iteration of Black Lives Matter

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The 2020 resurgence of Black Lives Matter (BLM) mobilised students in England to demand greater representation of racially minoritised voices in English curriculums—a call highlighted by stark inequity: just 1.5% of GCSE texts studied are by racially minoritised authors, despite racially minoritised students comprising 38.0% of the student ...

Seismic moment tensor and focal mechanism for earthquake of February 22, 2024 in eastern Slovakia (12:54:15 UTC, 21.75E°E, 49.03°N, depth 9 km, ML3.0)

open access: yesГеофизический журнал
The accuracy of the focal mechanism solution can depend very significantly on the number of stations used, especially in the case of weak earthquakes and sparse networks.

On the Depth of Earthquakes in the Delaware Basin: A Case Study along the Reeves–Pecos County Line

open access: yesThe Seismic Record, 2022
Increased rates of seismicity in the Delaware basin, Texas, accompanying unconventional petroleum development have created intensive interest in determining their cause.

Is the seismic moment tensor ambiguous at a material interface? [PDF]

open access: yesGeophysical Journal International, 2013
S U M M A R Y The moment tensors are unique and describe the body force equivalents of rupture processes in any medium including faulting at a material interface, defined as the contact of two media with non-zero velocity or density contrasts. From a practical point of view, however, the moment tensor inversion of sources near or at a material ...

Deep Compressed Seismic Learning for fast location and moment tensor inferences with natural and induced seismicity

open access: yesScientific Reports, 2022
Fast detection and characterization of seismic sources is crucial for decision-making and warning systems that monitor natural and induced seismicity. However, besides the laying out of ever denser monitoring networks of seismic instruments, the incorporation of new sensor technologies such as Distributed Acoustic Sensing (DAS) further challenges our ...

Interactive visualization of scattered moment tensor data

open access: yes, 2022
Paper 78680IMoment tensors derived from seismic measurements during earthquakes are related to stress tensors and keep important information about surface displacement in the earth's mantle. We present methods facilitating an interactive visualization of
