Crustal heterogeneity effects on coseismic deformation: numerical simulation of the 2008 MW 7.9 Wenchuan earthquake

Frontiers in Earth Science, 2023
Coseismic deformation of large earthquakes causes significant property damages and fatalities, which requires quantitative research of multiple disciplines such as geodesy, geological investigation, seismic tomography, and seismic dislocation theory. The

Coseismic Underground Rupture, Geometry, Historical Surface Deformations, and Seismic Potentials of the 28 March 2019 Mw 5.04 Mangya Earthquake Fault [PDF]

Tectonics, 2020
AbstractThe 28 March 2019 Mw 5.04 Mangya earthquake damaged eight ongoing drilling boreholes in the oil‐production Yingxiong Ling (YXL) area, southwestern Qaidam of northern Tibet. The borehole damages provide an opportunity to measure directly the coseismic slips, the rupture area, and the seismic moment.

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Coseismic surface‐ruptures and crustal deformations of the 2008 Wenchuan earthquake Mw7.9, China

Geophysical Research Letters, 2009
The irregularly distributed surface fault‐ruptures of the Wenchuan earthquake spanned over 200 km along the Longmen Shan(LMS) fault zone. Through field investigations, we found over 10 coseismic surface‐ruptures, with maximum vertical displacements of approximately 6 m on the Yingxiu‐Beichuan fault and 2 m on the Guanxian‐Anxian fault; however, the ...

Mechanical Decoupling Across the Deep Megathrust Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract We examine stress and strength across the deep subduction plate boundary at ∼60 km depth offshore northeastern Japan, near the downdip seismic limit of the megathrust. High‐frequency (2–5 Hz) moment tensor inversion of ∼2,000 M 2–3.5 earthquakes, integrated with existing catalogs, increases the number of focal mechanisms by more than a factor ...

Subsurface Deformation and Recovery From the Ridgecrest Mw 7.1 Earthquake Revealed by P‐Wave Velocity Time‐Lapse Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate co‐ and post‐seismic P‐wave velocity (Vp) changes following the July 2019 Mw 7.1 Ridgecrest strike‐slip earthquake using time‐lapse tomography from 50,345 P‐wave arrivals (2011–2024). Co‐seismically, Vp changes correspond to the volumetric strain change lobes of the earthquake, increasing in compressional zones and decreasing in

Liquefaction-induced large-scale ground deformation triggered by the 7 January 2025 MS 6.8 Dingri earthquake: characteristics and formation mechanisms

Dizhi lixue xuebao
Objective  In liquefaction-susceptible geological settings, the spatial superimposition of earthquake-induced liquefaction and coseismic fault rupture renders the genetic attribution of surface deformation highly ambiguous, yet systematic field ...

Shallow geological structures triggered during the Mw 6.4 Meinong earthquake, southwestern Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2017
The Meinong earthquake generated up to ~10 cm surface displacement located 10 - 35 km west of the epicenter and monitored by InSAR and GPS. In addition to coseismic deformation related to the deep earthquake source, InSAR revealed three sharp surface ...

Structural Features of Coseismic Surface Ruptures

, 2017
Coseismic surface ruptures created different structural features in each of the four principal rupture segments (Lin 2017). The southwest segment is branched into two zones: Zone-S1 and Zone-2. Zone-S1 is mainly composed of distinct shear faults, left-stepping echelon cracks, and mole tracks occurred mostly along the main segment of the Hinagu fault ...
