Decaying Post-Seismic Deformation Observed on the Korean Peninsula Following the 2011 Tohoku-Oki Earthquake [PDF]

Sensors, 2021
We investigated decaying post-seismic deformation observed on the Korean Peninsula associated with the 2011 Mw 9.0 Tohoku-Oki earthquake using Global Navigation Satellite System (GNSS).

Co-Seismic Inversion and Post-Seismic Deformation Mechanism Analysis of 2019 California Earthquake [PDF]

Remote Sensing, 2021
In July 2019, a series of seismic events, including a magnitude (Mw) 7.1 mainshock and Mw 6.4 foreshock, occurred in Eastern California. Studying these seismic events can significantly improve our understanding of the Eastern California tectonic ...

The effects of rheological layering on post-seismic deformation [PDF]

Geophysical Journal International, 2006
SUMMARY We examine the effects of rheological layering on post-seismic deformation using models of an elastic layer over a viscoelastic layer and a viscoelastic half-space. We extend a general linear viscoelastic theory we have previously proposed to models with two layers over a half-space, although we only consider univiscous Maxwell and biviscous ...

Post-seismic relaxation process and vertical deformation following the 2008 Ms8.0 Wenchuan earthquake, China

Geodesy and Geodynamics, 2012
The post-seismic horizontal and vertical deformations following the 2008 Ms8.0 Wenchuan earthquake are inferred from GPS and precise leveling data. The post-seismic relaxation process is measured using CPS data from campaign stations located around the ...

Numerical simulation of influences of the earth medium's lateral heterogeneity on co- and post-seismic deformation

Geodesy and Geodynamics, 2015
Many studies revealed that the Earth medium's lateral heterogeneity can cause considerable effects on the co- and post-seismic deformation field. In this study, the three-dimensional finite element numerical method are adopted to quantify the effects of ...

Post-Seismic Deformation from the 2009 Mw 6.3 Dachaidan Earthquake in the Northern Qaidam Basin Detected by Small Baseline Subset InSAR Technique

Sensors, 2016
On 28 August 2009, one thrust-faulting Mw 6.3 earthquake struck the northern Qaidam basin, China. Due to the lack of ground observations in this remote region, this study presents high-precision and high spatio-temporal resolution post-seismic ...

Rheology of the Zagros Lithosphere from Post-Seismic Deformation of the 2017 Mw7.3 Kermanshah, Iraq, Earthquake [PDF]

Remote Sensing, 2020
We use 2018–2020 Sentinel-1 InSAR time series data to study post-seismic deformation processes following the 2017 Mw 7.3 Kermanshah, Iraq earthquake. We remove displacements caused by two large aftershock sequences from the displacement field. We find that for a six month period the response is dominated by afterslip along the up-dip extension of the ...

A degraded cantilever model for post insulators under cyclic loading [PDF]

Scientific Reports
Support-type tubular busbar structures widely used in substations are inherently vulnerable to earthquake-induced damage. This study experimentally characterizes the load-resisting behavior and deformation mechanisms of post insulators under quasi-static

Transient Creep in Olivine at Shallow Mantle Pressures: Implications for Time‐Dependent Rheology in Post‐Seismic Deformation

Geophysical Research Letters
Transient creep in olivine aggregates has been studied by stress‐relaxation experiments at pressures of 1.7–3.6 GPa and at temperatures of ≤1020 K in a DIA apparatus. Time‐dependent deformation of olivine at small strains (
