Active Deformation Patterns in the Northern Birjand Mountains of the Sistan Suture Zone, Iran

open access: yesApplied Sciences, 2022
In this paper, faults, one of the most important causes of geohazards, were investigated from a kinematic and geometric viewpoint in the northern part of the Sistan suture zone (SSZ), which serves as the boundary between the Afghan and Lut blocks ...

Injection-induced fault slip and associated seismicity in the lab: Insights from source mechanisms, local stress states and fault geometry

open access: yesEarth and Planetary Science Letters
Probing source mechanisms of natural and induced earthquakes is a powerful tool to unveil associated rupture kinematics. The source processes of failure and slip instability driven by stress loading are affected by fault geometry, but the source ruptures

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.

The influence of fault geometry on small strike-slip fault mechanics [PDF]

open access: yesJournal of Structural Geology, 2015
Abstract Meter-scale subvertical strike-slip fault traces in the central Californian Sierra Nevada exhibit geometric complexities that significantly contribute to their mechanical behavior. Sections of faults that opened at depth channelized fluid flow, as evidenced by hydrothermal mineral infillings and alteration haloes.

Insights on the dip of fault zones in Southern California from modeling of seismicity with anisotropic point processes

open access: yesSeismica
Accurate models of fault zone geometry are important for scientific and hazard applications. While seismicity can provide high-resolution point measurements of fault geometry, extrapolating these measurements to volumes may involve making strong ...

Complex strike-slip faulting during the 2021 Mw7.4 Maduo earthquake

open access: yesCommunications Earth & Environment, 2023
Fault geometry is an essential component for understanding earthquake genesis and dynamic rupture propagation. Here we employed space-based geodetic observations and geological survey, adopting a fully Bayesian approach, to probabilistically estimate the

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.

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 ...
