Role of Poroelasticity During the Early Postseismic Deformation of the 2010 Maule Megathrust Earthquake

Geophysical Research Letters, 2022
Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere‐asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and poroelastic processes ...

Coseismic and Postseismic Crustal Deformation Associated With the 2016 Kumamoto Earthquake Sequence Revealed by PALSAR‐2 Pixel Tracking and InSAR

Earth and Space Science, 2020
Coseismic and postseismic crustal deformations caused by earthquake episodes are important in understanding the mechanisms of these episodes as well as the fault rheology near an epicentral area.

Viscoelastic relaxation of the upper mantle and afterslip following the 2014 MW8.1 Iquique earthquake

Earthquake Research Advances, 2021
An improved understanding of postseismic crustal deformation following large subduction earthquakes may help to better understand the rheological properties of upper mantle and the slip behavior of subduction interface.

Mode of Strain Release Associated with Major Earthquakes in Japan [PDF]

, 1973
It is now widely accepted that most shallow earthquakes are caused by a sudden release of tectonic stress, and therefore strain, in the form of faulting (56, Chap. 14).

Seismogenic, coseismic and postseismic deformation and stress evolution of the 2008 Wenchuan earthquake: Numerical simulation analysis

Dizhi lixue xuebao, 2021
The 2008 MS 8.0 Wenchuan earthquake occurred in the Longmenshan fault zone, which has complex geological background, strong surface relief, and heterogeneous elastic-viscous structures; however, the seismic risk of the Longmenshan fault zone was ...

Block Motion Changes in Japan Triggered by the 2011 Great Tohoku Earthquake [PDF]

, 2017
Plate motions are governed by equilibrium between basal and edge forces. Great earthquakes may induce differential static stress changes across tectonic plates, enabling a new equilibrium state.

Postseismic deformation and the strength of ductile shear zones [PDF]

Earth, Planets and Space, 2014
A good understanding of the rheology and strength of the whole crust is needed to obtain a physics-based earthquake prediction models. However, geodynamics-based and laboratory-based strength estimates disagree. Geodynamics tend to indicate that the actual strength of the plastic crust is less than deduced from laboratory experiments.

Homogeneous vs heterogeneous subduction zone models: Coseismic and postseismic deformation [PDF]

Geophysical Research Letters, 2001
A finite‐element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic half‐spaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic deformation predictions for the 1995 Colima‐Jalisco Mw =8.0 earthquake.

Core-mantle boundary deformations and J2 variations resulting from the 2004 Sumatra earthquake

, 2007
The deformation at the core-mantle boundary produced by the 2004 Sumatra earthquake is investigated by means of a semi-analytic theoretical model of global coseismic and postseismic deformation, predicting a millimetric coseismic perturbation over a ...

Heterogeneous coupling of the Sumatran megathrust constrained by geodetic and paleogeodetic measurements [PDF]

, 2008
Geodetic and paleogeodetic measurements of interseismic strain above the Sumatran portion of the Sunda subduction zone reveal a heterogeneous pattern of coupling.
