Spatial–temporal properties of afterslip associated with the 2015 Mw 8.3 Illapel earthquake, Chile

open access: yesEarth, Planets and Space, 2021
In order to characterize the spatial–temporal properties of postseismic slip motions associated with the 2015 Illapel earthquake, the daily position time series of 13 GNSS sites situated at the near-field region are utilized.

Coseismic and postseismic fault slip characteristics of the 2020 MW6.3 Nima earthquake

open access: yes地球与行星物理论评, 2023
The 2020 MW6.3 Nima earthquake occurred in the northern Yibug Caka graben on the Qiangtang Block of the Tibetan Plateau. The epicentral area has complex geological structures, topography, and geomorphology, and there are few near-field ground observation

Realization approach of non-linear postseismic deformation model for Taiwan semi-kinematic reference frame

open access: yesEarth, Planets and Space, 2020
Surface displacements associated with earthquake-cycle deformation of active faults significantly influence the accuracy of geodetic datum and reference frames, especially for the Taiwan area with high plate convergence and deformation rates.

Improvement on spatial resolution of a coseismic slip distribution using postseismic geodetic data through a viscoelastic inversion

open access: yesEarth, Planets and Space, 2020
Obvious crustal deformation is observed during a postseismic period as well as a coseismic period associated with a large earthquake. Major mechanisms of transient postseismic deformation are known as afterslip and viscoelastic relaxation.

Probing time-dependent afterslip and viscoelastic relaxation following the 2015 Mw7.8 Gorkha earthquake based on the 3-D finite-element model

open access: yesEarth, Planets and Space, 2020
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha earthquake.

INCORPORATING INDEPENDENT COMPONENT ANALYSIS AND MULTI-TEMPORAL SAR TECHNIQUES TO RETRIEVE RAPID POSTSEISMIC DEFORMATION [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
This study investigates the ongoing postseismic deformation induced by two moderate mainshocks of Mw 6.1 and Mw 6.0, 2017 Hojedk earthquake in Southern Iran. Available Sentinel-1 TOPS C-band Synthetic Aperture Radar (SAR) images over about one year after

Omori‐like decay of postseismic velocities following continental earthquakes

open access: yesGeophysical Research Letters, 2017
Various mechanisms have been proposed to explain the transient, enhanced surface deformation rates following earthquakes. Unfortunately, these different mechanisms can produce very similar surface deformation patterns leading to difficulty in ...

Heterogeneous rheology of Japan subduction zone revealed by postseismic deformation of the 2011 Tohoku-oki earthquake

open access: yesProgress in Earth and Planetary Science, 2023
The 2011 Tohoku-oki earthquake produced the most well-recorded postseismic deformation of any megathrust earthquake in the world. Over the last decade, researchers have used a dense and widespread geodetic network of more than 1300 Global Navigation ...

Function Model Based on Nonlinear Transient Rheology of Rocks: An Analysis of Decadal GNSS Time Series After the 2011 Tohoku‐oki Earthquake

open access: yesGeophysical Research Letters, 2023
The postseismic Global Navigation Satellite System (GNSS) time series after the 2011 Tohoku‐oki earthquake is often empirically explained by one or more logarithmic and exponential decay functions.
