Using historical aerial images to accurately locate the urban "invisible" active faults: A case study of the Shuiyu fault of the Datong Basin in Shanxi province

Dizhi lixue xuebao, 2021
Active fault is a major risk source of urban earthquake disaster. Accurately identifying the spatial geometry distribution features of active fault is the basis for urban seismic risk migration.

Normal fault interactions in seismic cycles and the impact of fault network geometry

Journal of Geophysical Research: Solid Earth
Understanding the mechanisms behind the characteristics of earthquake cycles on normal faults is challenging due to their long recurrence times. Despite their moderate magnitude, normal faulting earthquakes can produce considerable damage. We investigate the effects of fault network geometry and spacing on the seismic cycle of a system of two normal ...

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Geometry, evolution and scaling of fault relay zones in 3D using detailed observations from outcrops and 3D seismic data [PDF]

, 2011
A new surface attribute was developed during the course of the thesis, which enables fault-related deformation – specifically, the apparent dip of mapped horizons measured in a direction perpendicular to the average strike of a fault array (here termed ...

Fluid flow in crustal fault zones with varying lengthwise thickness: application to the Margeride fault zone (French Massif Central)

Geothermal Energy
Crustal fault zones, holding promise as potential geothermal reservoirs, remain largely untapped and unexplored. Located in the southern Massif Central, France, the Margeride fault zone (MFZ) varies in thickness (lateral extension perpendicular to the ...

Stochastic model of earthquake fault geometry [PDF]

Geophysical 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 ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

Advanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Study on the influence of complex fault geometry on earthquake risk assessment based on physical simulation: a case study of the Zhujiangkou Fault in the Guangdong–Hong Kong–Macao Greater Bay Area

Geomatics, Natural Hazards & Risk
Dynamic rupture simulations offer a physics-based approach to model earthquake processes and assess seismic hazards. While these simulations rely on stress state, friction, and geometry, the influence of fault geometry on societal risk remains ...

Bimodal seismicity in the Himalaya controlled by fault friction and geometry [PDF]

Nature Communications, 2019
AbstractThere is increasing evidence that the Himalayan seismicity can be bimodal: blind earthquakes (up to Mw ~ 7.8) tend to cluster in the downdip part of the seismogenic zone, whereas infrequent great earthquakes (Mw 8+) propagate up to the Himalayan frontal thrust.
