Coseismic and postseismic deformation associated with the 2003 Chengkung, Taiwan, earthquake [PDF]

Geophysical Journal International, 2009
SUMMARY We use GPS-derived coseismic and postseismic displacements of the 2003 Mw 6.8 Chengkung, Taiwan, earthquake to examine seismogenic behaviour of the southern Longitudinal Valley. We invert for fault slip on the Chihshang fault, a segment of the Longitudinal Valley fault, based on a simplified layered earth model and a listric-shape fault ...

Modulation of Slow Slip Event Characteristics Throughout the Costa Rica Subduction Zone Earthquake Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

Coseismic slip distribution and 3D deformation field simulation of the Menyuan Mw 6.7 earthquake in Qinghai based on InSAR constraint

地质科技通报
On January 8, 2022, a Mw 6.7 earthquake stuck Menyuan Hui Autonomous County, Qinghai Province, resulting in extensive surface ruptures and the closure of the Lanzhou-Xinjiang high-speed railway.

Investigating Postseismic Creep in the Laboratory: Testing Dislocation‐Based Models for Transient Creep in the Upper Mantle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

Coseismic and early postseismic deformation due to the 2021 M7.4 Maduo (China) earthquake

Geophysical Research Letters, 2021
Key Points: • We use Sentinel-1 Synthetic Aperture Radar (SAR) data to derive a finite fault model for the 2021 M7.4 Maduo (Qinghai, China) earthquake • The along-strike averaged coseismic slip has a maximum at depth of 3-4 km, with an amplitude of ∼2.5 m.

Decadal Creep Acceleration on the Northern Japan Trench Driven by Erosion of Heterogeneously Locked Asperities

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.

GPS Constraints on the Mw = 7.5 Ometepec Earthquake Sequence, Southern Mexico: Coseismic and Post-Seismic Deformation [PDF]

, 2014
We use continuous GPS measurements from 31 stations in southernMexico to model coseismic slip and post-seismic deformation from the 2012 March 20 Mw = 7.5 Ometepec earthquake, the first large thrust earthquake to occur below central Mexico during the ...

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 ...

Deformation Features of Coseismic Surface Rupture

, 2017
The term coseismic surface rupture is defined as a surface fracture produced by a current or large historic earthquake. The term is interchangeable with surface earthquake fault and earthquake fault in Japan, which is enhanced for the topographic morphology and geometry of surface fractures formed during large earthquakes [Research Group for Active ...

Cessation of Nearby Low‐Frequency Earthquake Activity Following the December 2024 Mw 7.0 Mendocino Earthquake: The Likely Role of Pore Pressure Reductions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Earthquakes affect surrounding fault systems through multiple mechanisms. Here, we examine a rare cessation of activity in 27 families of low‐frequency earthquakes (LFEs) that likely reflect fault creep at the southern edge of Cascadia subduction, near the Mendocino triple junction.
