Coseismic sediment deformation during the 1989 Loma Prieta earthquake [PDF]

, 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.

A Persistent Scatterer Interferometry-Based Parametric Framework for Characterizing Pre-, Co-, and Post-Seismic Surface Deformation: Application to the 2025 Dingri Earthquake (Southern Tibet)

Remote Sensing
Persistent Scatterer Interferometry (PSI) provides dense and temporally continuous measurements of ground deformation, offering a robust framework for investigating, among other phenomena, earthquake-related surface deformation.

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 ...

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 ...

Impact of topography and three-dimensional heterogeneity on coseismic deformation

, 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 Deformation and Fault Inversion of the 2017 Jiuzhaigou Ms 7.0 Earthquake: Constraints from Steerable Pyramid and InSAR Observations

Remote Sensing, 2022
The 8 August 2017 Ms 7.0 Jiuzhaigou earthquake was generated in the transition zone between the Tazang fault, Huya fault, and Minjiang fault, all being part of the East Kunlun fault system.

Why blind thrust faults do not propagate to the Earth's surface: Numerical modeling of coseismic deformation associated with thrust‐related anticlines [PDF]

Journal of Geophysical Research: Solid Earth, 1997
High fault‐tip stress concentrations are associated with coseismic slip on blind thrust faults and suggest that these structures should readily propagate to the Earth's surface. Seismic profiles of blind‐thrust‐related earthquakes reveal diffuse zones of aftershocks surrounding the fault tip which are attributed to inelastic deformation, such as ...

A Transient in Surface Motions Dominated by Deep Afterslip Subsequent to a Shallow Supershear Earthquake: The 2018 Mw7.5 Palu Case

Geochemistry, Geophysics, Geosystems, 2021
The 2018 Mw7.5 Palu earthquake is a remarkable strike‐slip event due to its nature as a shallow supershear fault rupture across several segments and a destructive tsunami that followed coseismic deformation. GPS offsets in the wake of the 2018 earthquake

Coseismic Tectonic Surface Deformation during the 2010 Maule, Chile, M _w 8.8 Earthquake

Earthquake Spectra, 2012
Tectonic deformation from the 2010 Maule (Chile) M w 8.8 earthquake included both uplift and subsidence along about 470 km of the central Chilean coast. In the south, deformation included as much as 3 m of uplift of the Arauco Peninsula, which produced emergent marine platforms and affected ...

Persistent scatterer interferometry to monitor mining related ground surface deformation for data-driven modelling [PDF]

, 2006
The monitoring, interpretation and prediction of gradual ground surface deformation are critical factors in the understanding of earth systems. In many parts of the world, particularly in coastal areas where resources are often easily transportable and ...
