Faults as Volumetric Weak Zones in Reservoir-Scale Hydro-Mechanical Finite Element Models—A Comparison Based on Grid Geometry, Mesh Resolution and Fault Dip

open access: yesEnergies, 2020
An appropriate representation of faults is fundamental for hydro-mechanical reservoir models to obtain robust quantitative insights into the spatial distribution of stress, strain and pore pressure.

Stochastic model of earthquake fault geometry [PDF]

open access: yesGeophysical Journal International, 1982
Summary An earthquake fault pattern is assumed to consist of a system of infinitesimal, elementary dislocation loops. After an initial dislocation, subsequent ruptures occur according to a critical branching process. The position of each secondary dislocation loop is randomly shifted, along the initial fault-plane, from the location of the main ...

Towards Geometry-Preserving Domain Adaptation for Fault Identification

open access: yes, 2023
In most industries, the working conditions of equipment vary significantly from one site to another, from one time of a year to another, and so on. This variation poses a severe challenge for data-driven fault identification methods: it introduces a change in the data distribution.

A stochastic approach to reconstruction of faults in elastic half space [PDF]

open access: yes, 2018
We introduce in this study an algorithm for the imaging of faults and of slip fields on those faults. The physics of this problem are modeled using the equations of linear elasticity.

Deformation due to the 17 August 1999 Izmit, Turkey, earthquake measured from SPOT images [PDF]

open access: yes, 2002
The geometry of the ruptured areas and the coseismic slip distribution data are key to highlighting the behavior of seismic faults. This information is generally retrieved from field investigations and geodetic measurements or synthetic aperture radar ...

Accounting for uncertain fault geometry in earthquake source inversions – II: application to the Mw 6.2 Amatrice earthquake, central Italy

open access: yesGeophysical Journal International, 2018
Our understanding of earthquake sources is limited by the availability and the quality of observations and the fidelity of our physical models. Uncertainties in our physical models will naturally bias our inferences of subsurface fault slip.

Effects of fault geometry uncertainty on tsunami inversion: a study based on the 2011 Tohoku earthquake

open access: yesEarth, Planets and Space
Finite-fault inversion of tsunami waveforms requires prior knowledge of fault geometry, which is often subject to considerable uncertainty. Quantifying effects of such uncertainty is essential for evaluating the reliability of inversion results derived ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural architecture and late Cenozoic tectonic evolution of the Ulsan Fault Zone, SE Korea: New insights from integration of geological and geophysical data

open access: yesFrontiers in Earth Science, 2023
Integration of geological and geophysical data is essential to elucidate the configuration and geometry of surface and subsurface structures, as well as their long-term evolution.

Earthquake statistics and fractal faults

open access: yes, 1996
We introduce a Self-affine Asperity Model (SAM) for the seismicity that mimics the fault friction by means of two fractional Brownian profiles (fBm) that slide one over the other.
