High precision coseismic deformation monitoring method based on time-series InSAR analysis

open access: yes地球与行星物理论评, 2023
Interferometry Synthetic Aperture Radar (InSAR) technology has become an important tool for monitoring surface deformation with its all-day, all-weather ground monitoring and high spatial resolution, and has been widely applied to seismic deformation ...

Fault mechanics and post-seismic deformation at Bam, SE Iran [PDF]

open access: yesGeophysical Journal International, 2017
The extent to which aseismic deformation relaxes co-seismic stress changes on a fault zone is fundamental to assessing the future seismic hazard following any earthquake, and in understanding the mechanical behaviour of faults. Here we use models of stress-driven afterslip and viscoelastic relaxation, in conjunction with post-seismic InSAR measurements,

Deformation Behavior and Inferred Seismic Properties of Tonalitic Migmatites at the Time of Pre‐melting, Partial Melting, and Post‐Solidification

open access: yesGeochemistry, Geophysics, Geosystems, 2021
As seismic data from the lower crust becomes more readily available, it is important to link seismic properties to the ongoing processes within lower crustal evolution.

Post-seismic crustal internal deformation in a layered earth model

open access: yesGeophysical Journal International, 2021
SUMMARY This study introduces a novel method for computing post-seismic crustal internal deformation in a layered earth model. The surface dislocation Love number (DLN) calculated by the reciprocity theorem was implemented as the initial value.

Effects of Earth's gravitation and compressibility on co- and post-seismic deformations

open access: yesGeophysical Journal International, 2022
SUMMARY In this paper, we systematically analyse the effect of Earth's gravitation and compressibility on co- and post-seismic deformations. Based on the analytical solution of dislocation Love number (DLN) in a non-gravitational and incompressible homogeneous Earth model, it was seen that reducing the density of the homogeneous Earth ...

Glacial isostatic adjustment and post-seismic deformation in Antarctica [PDF]

open access: yesGeological Society, London, Memoirs, 2022
Abstract This chapter reviews glacial isostatic adjustment (GIA) and post-seismic deformation in Antarctica. It discusses numerical models and their inputs, and observations and inferences that have been made from them. Both processes are controlled by mantle viscosity but their forcings are different.

Influence of lithospheric and mantle stratification on global post‐seismic deformation [PDF]

open access: yesGeophysical Research Letters, 1997
A new class of multilayered, viscoelastic Earth models based on PREM, with an incompressible, linear, viscoelastic Maxwell rheology, is applied to the modeling of co‐seismic and post‐seismic deformation following large earthquakes. The novelty of our approach stands on the usage, for the first time in post‐seismic studies, of a fully analytical scheme ...

Co- and post-seismic Deformation Mechanisms of the MW 7.3 Iran Earthquake (2017) Revealed by Sentinel-1 InSAR Observations

open access: yesRemote Sensing, 2019
The extraction of high-accuracy co- and post-seismic deformation fields and inversions of seismic slip distributions is significant in the comprehension of seismogenic mechanisms.

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Measuring and Modeling Viscoelastic Relaxation of the Lithosphere with Application to the Northern Volcanic Zone, Iceland [PDF]

open access: yes, 2010
Viscoelastic relaxation of the stress perturbation caused by an earthquake or diking event can produce measurable ground deformation over 100 km away from the source. We consider the role of viscoelastic relaxation in two different contexts.
