GPS source solution of the 2004 Parkfield earthquake [PDF]

, 2014
We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (

Numerical simulations to explain the coseismic electromagnetic signals: a case study for a M5.4 aftershock of the 2016 Kumamoto earthquake

Earth, Planets and Space, 2019
Coseismic electromagnetic (EM) signals that appear from the P arrival were observed in a volcanic area during the 2016 Kumamoto earthquake. In this study, we conduct numerical simulations to explain the coseismic EM signals observed for a M5.4 aftershock

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 ≈

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.

InSAR-constrained parallel elastic finite element models for fault coseismic dislocation inversion: a case study of the 2016 MW 5.9 Menyuan earthquake

Frontiers in Earth Science
The study of fault coseismic dislocation distribution is crucial for understanding fault stress release, fault sliding behavior, and surface deformation during seismic events.

Influences of across-strike heterogeneous viscosity on the earthquake cycle in a three-dimensional strike-slip fault model

Earthquake Research Advances, 2023
Geodetic observations have shown that there exist large differences in the viscosity of the deep lithosphere across many large strike-slip faults. Heterogeneity in lithospheric viscosity structure can influence the efficiency of stress transfer and thus ...

Core-mantle boundary deformations and J2 variations resulting from the 2004 Sumatra earthquake

, 2007
The deformation at the core-mantle boundary produced by the 2004 Sumatra earthquake is investigated by means of a semi-analytic theoretical model of global coseismic and postseismic deformation, predicting a millimetric coseismic perturbation over a ...

Heterogeneous Fault Mechanisms of the 6 October 2008 MW 6.3 Dangxiong (Tibet) Earthquake Using Interferometric Synthetic Aperture Radar Observations

Remote Sensing, 2016
Most current crustal deformation models do not account for topographic effects, crustal lateral variations, and complex fault geometries. To overcome these limitations, we apply finite element models constrained by interferometric Synthetic Aperture ...
