FrosPy: A Modular Python Toolbox for Normal Mode Seismology [PDF]

open access: yes, 2022
We present free oscillations Python (FrosPy), a modular Python toolbox for normal mode seismology, incorporating several Python core classes that can easily be used and be included in larger Python programs.

The finite-volume method in computational rheology [PDF]

open access: yes, 2012
The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

Structured regularization based velocity structure estimation in local earthquake tomography for the adaptation to velocity discontinuities

open access: yesEarth, Planets and Space, 2022
We propose a local earthquake tomography method that applies a structured regularization technique to determine sharp changes in Earth’s seismic velocity structure using arrival time data of direct waves.

MLReal: Bridging the gap between training on synthetic data and real data applications in machine learning

open access: yesArtificial Intelligence in Geosciences, 2022
Among the biggest challenges we face in utilizing neural networks trained on waveform (i.e., seismic, electromagnetic, or ultrasound) data is its application to real data.

Effects of induced stress on seismic forward modelling and inversion [PDF]

open access: yes, 2018
We demonstrate how effects of induced stress may be incorporated in seismic modelling and inversion. Our approach is motivated by the accommodation of pre-stress in global seismology.

Back‐Projection Imaging of Extended, Diffuse Sources of Volcano‐Tectonic Seismicity During June 2010 at Sierra Negra Volcano, Galápagos

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Seismic signals generated by subsurface volcano‐tectonic processes commonly have low signal‐to‐noise ratios that make it difficult to resolve both 3‐D subsurface structures and seismic source locations using established seismic imaging methods (e.g ...

The Orthotropy Effect of Underground Inclusion on the Seismic Response of Ground Surface [PDF]

open access: yesمهندسی عمران شریف
This paper presents a formulation of the attenuated orthotropic time-domain half-space boundary element method for analyzing the orthotropic effect of underground inclusions subjected to transient SH-waves.

Direct observations of causal links in plastic events and relevance to earthquake seismology [PDF]

open access: yes, 2023
Earthquakes are complex physical processes driven by stick-slip motion on a sliding fault. After the main event, a series of aftershocks is usually observed.

Seismic Structure of the Upper Mantle Beneath Eastern Asia From Full Waveform Seismic Tomography

open access: yesGeochemistry, Geophysics, Geosystems, 2018
To better understand the subsurface behavior of subducting slabs and their relation to the tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large data set to determine a high‐resolution seismic model, FWEA18 (Full ...
