Uplift and subsidence associated with the great Aceh-Andaman earthquake of 2004 [PDF]

, 2006
Rupture of the Sunda megathrust on 26 December 2004 produced broad regions of uplift and subsidence. We define the pivot line separating these regions as a first step in defining the lateral extent and the downdip limit of rupture during that great M_w ≈

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

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 ...

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Evidence for postseismic deformation of the lower crust following the 2004 Mw6.0 Parkfield earthquake [PDF]

, 2011
Previous studies have shown that postseismic relaxation following the 2004 Mw6.0 Parkfield, CA, earthquake is dominated by afterslip. However, we show that some fraction of the afterslip inferred from kinematic inversion to have occurred immediately ...

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Influence of camera distortions on satellite image registration and change detection applications [PDF]

, 2008
Applications such as change detection and digital elevation model extraction from optical images require a rigorous modeling of the acquisition geometry.

Interpretation of the coseismic surface deformation of Wenchuan earthquake based on the theory of disclination and dislocation

IOP Conference Series: Materials Science and Engineering, 2019
Abstract A combination model of disclination-dislocation which can describe the three-dimensional translational and rotational motion of the fault is given. We used the combined model and the dislocation model to calculate the coseismic horizontal displacement of 102 points of Wenchuan earthquake respectively.

Exceptionally Elongated Strike‐Slip Rupture Caused by the 2025 MW 7.8 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The interplay between fault geometry and rupture behavior remains poorly understood. The 2025 Myanmar earthquake ruptured the Sagaing fault, a major continental strike‐slip fault with simple geometry. We integrated geodetic and teleseismic observations to investigate its rupture process through finite‐fault kinematic inversions and back ...

Surface ruptures and off-fault deformation of the October 2016 central Italy earthquakes from DInSAR data

Scientific Reports, 2022
Large magnitude earthquakes produce complex surface deformations, which are typically mapped by field geologists within the months following the mainshock. We present detailed maps of the surface deformation pattern produced by the M.
