Coseismic Ground Deformation Reproduced through Numerical Modeling: A Parameter Sensitivity Analysis
Geosciences, 2019 Coseismic ground displacements detected through remote sensing surveys are often used to invert the coseismic slip distribution on geologically reliable fault planes.

Influence of different factors on coseismic deformation of the 2015 Mw7.8 earthquake in Nepal [PDF]
Scientific Reports, 2023 In Geophysics, topographic factors are observations that can be directly measured, but they are often ignored to simplify the model. Studying the coseismic deformation caused by earthquakes helps accurately determine the epicenter's parameterization.

Improved coseismic deformation detection via SBAS InSAR-Hyperbolic tangent step model integration
International Journal of Applied Earth Observations and GeoinformationThe centimeter level deformation generated by small and medium-sized earthquakes contains rich information on tectonic activity, which is of great value for improving the coseismic deformation database and fault dynamics models.

Coseismic Shallow Slip Deficit Accounted for by Diffuse Off‐Fault Deformation
Geophysical Research LettersEarthquake ruptures produce fault slip and kilometer‐wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated.

COSEISMIC DEFORMATION FIELD AND FAULT SLIP DISTRIBUTION OF THE 2015 CHILE Mw8.3 EARTHQUAKE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 On September 16, 2015, a magnitude 8.3 earthquake struck west of Illapel, Chile. We analyzed Sentinel-1A/IW InSAR data on the descending track acquired before and after the Chile Mw8.3 earthquake of 16 September 2015.

Coseismic fault lubrication by viscous deformation [PDF]
Nature Geoscience, 2021 Despite the hazard posed by earthquakes, we still lack fundamental understanding of the processes that control fault lubrication behind a propagating rupture front and enhance ground acceleration. Laboratory experiments show that fault materials dramatically weaken when sheared at seismic velocities (>0.1 m s−1).

Impact of topography and three-dimensional heterogeneity on coseismic deformation [PDF]
Geophysical Journal International, 2019 Knowledge of deformation at plate boundaries has been improved greatly by the development of observational techniques in space geodesy. However, most theoretical and numerical models of coseismic deformation have remained very simple and do not include ...

Coseismic sediment deformation during the 1989 Loma Prieta earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2008 Inelastic horizontal sediment deformation from the MS 7.1, 17 October 1989 Loma Prieta earthquake has been estimated to be on the order of 20 cm at a site in Gilroy, California, about 32 km east of the epicenter. This estimate was based on combined deterministic‐stochastic simulations using ground motion data and sediment properties measured from in ...
