Seismogenic, coseismic and postseismic deformation and stress evolution of the 2008 Wenchuan earthquake: Numerical simulation analysis

open access: yesDizhi lixue xuebao, 2021
The 2008 MS 8.0 Wenchuan earthquake occurred in the Longmenshan fault zone, which has complex geological background, strong surface relief, and heterogeneous elastic-viscous structures; however, the seismic risk of the Longmenshan fault zone was ...

Coseismic and Early Postseismic Deformation of the 2020 Mw 6.4 Petrinja Earthquake (Croatia) Revealed by InSAR

open access: yesRemote Sensing, 2023
The largest earthquake (Mw 6.4) in northwestern Croatia ruptured the faults near the city of Petrinja on 29 December 2020, at 11:19 UTC. The epicenter was located ~3 km southwest of Petrinja, ~40 km southeast of Zagreb, the capital of the Republic of ...

Influence of anelastic surface layers on postseismic thrust fault deformation [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2000
We present the results of a systematic modeling study of postseismic deformation following blind thrust earthquakes. The results include qualitative and quantitative predictions of the surface movement caused by relaxation in viscoelastic near‐surface layers.

Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

The use of Terrestrial Laser Scanning in characterizing active tectonic processes from postseismic slip to the long term growth of normal faults [PDF]

open access: yes, 2012
This thesis investigates two main hypotheses regarding uncertainty in the measurement of paleoseismic offsets used to estimate fault activity and paleoearthquake magnitudes on normal faults: (1) That variations in fault geometry have a significant effect

Grain Size and Fluid Effects on the Frictional Behavior of Simulated Carbonate Fault Gouge

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Carbonate rocks exhibit a span of clast and grain size in fault zones. However, the effect of grain size distribution on the frictional behavior of carbonate faults and its implications for natural and induced seismicity remain poorly understood.

Rheologic constraints on the upper mantle from 5 years of postseismic deformation following the El Mayor‐Cucapah earthquake [PDF]

open access: yes, 2016
We analyze five years of Southern California GPS data following the Mw=7.2 El Mayor‐Cucapah earthquake. We observe transient postseismic deformation which persists for 3 years at epicentral distances greater than ∼200 km.

OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]

open access: yes, 1996
In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.
