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.

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 ...

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 ...

Earthquake monitoring and high-resolution velocity tomography for the central Longmenshan fault zone by a temporary dense seismic array

Earth and Planetary Physics
The Longmenshan (LMS) fault zone is located at the junction of the eastern Tibetan Plateau and the Sichuan Basin and is of great significance for studying regional tectonics and earthquake hazards.

A Multiplex Rupture Sequence Under Complex Fault Network Due To Preceding Earthquake Swarms During the 2024 Mw 7.5 Noto Peninsula, Japan, Earthquake

Geophysical Research Letters
A devastating earthquake with moment magnitude 7.5 occurred in the Noto Peninsula in central Japan on 1 January 2024. We estimate the rupture evolution of this earthquake from teleseismic P‐wave data using the potency‐density tensor inversion method ...

Geometric Controls on Cascading and Supershear Rupture Across a Wavy Strike-Slip Fault

Geosciences
Fault waviness can control whether earthquakes arrest, cascade, or transition to supershear rupture, yet its interaction with hypocentral position and free-surface proximity remains poorly constrained. We use three-dimensional spontaneous dynamic-rupture

Excitation of long-period free oscillations by the 2011 Tohoku earthquake: Numerical experiments and influence of source parameters

Geodesy and Geodynamics
Long-period free oscillations provide robust information for the spatio-temporal characteristics of large earthquakes. In this study, we employ a normal-mode summation algorithm to generate three-component seismograms within an aspherical, anelastic, and
