Postseismic relaxation across the Central Nevada Seismic Belt [PDF]

Journal of Geophysical Research: Solid Earth, 2003
Two GPS geodetic surveys across the Basin and Range (BR) province of western North America have detected an anomalous compression east of the Central Nevada Seismic Belt (CNSB). The first network, installed by the U.S. Geological Survey along an east‐west trending transect across the BR at approximately 40°N, consisted of 63 monuments observed campaign

Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

Continuous estimation of coseismic and early postseismic slip phenomena via the GNSS carrier phase to fault slip approach: a case study of the 2011 Tohoku-Oki sequence

Progress in Earth and Planetary Science, 2022
The transition process from coseismic to early postseismic phenomena within a half-day remains a significant topic for understanding the slip budget and friction properties of the fault.

Coseismic and postseismic motion of a landslide: Observations, modeling, and analogy with tectonic faults [PDF]

Geophysical Research Letters, 2014
AbstractWe document the first time series of a landslide reactivation by an earthquake using continuous GPS measurements over the Maca landslide (Peru). Our survey shows a coseismic response of the landslide of about 2 cm, followed by a relaxation period of 5 weeks during which postseismic slip is 3 times greater than the coseismic displacement itself.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Coseismic and Postseismic Displacements of the 2024 Mw 7.0 Wushi, China, Earthquake Observed from SAR Images

On 23 January 2024, a magnitude (Mw) 7.0 earthquake struck Wushi County (China) in the southwestern Tian Shan orogen. Both Sentinel-1 and Advanced Land Observation Satellite-2 radar images were used to obtain coseismic displacements with interferometry ...

Poroelastic effects associated with earthquakes on overpressured reverse and normal faults

Frontiers in Earth Science
Earthquakes in fluid-saturated rocks induce sudden changes in pore-pressures that can lead to appreciable postseismic deformation. However, earthquakes can also release fluids from overpressured parts of the crust, which can also contribute to additional

Geodetic Resolution of the Interplay Between Earthquakes and Slow Slip in the Hikurangi Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Interactions between slow slip and earthquakes remain poorly understood. We examine such an interaction in the central Hikurangi subduction zone where several moderate (Mw 4–5+) earthquakes occurred during a deep, 2‐year M7 slow slip event that started in 2021.

Fault Kinematic Controls on the Spatio‐Temporal Proximity of the 2023 Mw 7.8‐7.7 Türkiye Earthquakes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The mechanism governing the spatio‐temporal proximity of the 2023 Mw 7.8‐7.7 Türkiye earthquakes remains enigmatic. Here, we used dense geodetic observations integrated with dual‐fault screw dislocation, Euler‐vector‐constrained block, and strain‐rate models to investigate the interseismic kinematics and pre‐stress state of the East Anatolian ...

Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...
