Integration of InSAR time series analysis and water vapour correction for mapping postseismic deformation after the 2003 Bam (Iran) Earthquake [PDF]

, 2009
Atmospheric water-vapor effects represent a major limitation of interferometric synthetic aperture radar (InSAR) techniques, including InSAR time-series (TS) approaches (e.g., persistent or permanent scatterers and small-baseline subset).

Omori-like slow decay (p < 1) of postseismic displacement rates following the 2011 Tohoku megathrust earthquake

Earth, Planets and Space, 2020
We infer the postseismic deformation mechanisms following the 2011 Tohoku megathrust earthquake via an analysis of onshore geodetic observations. We focus on the temporal decay characteristics of postseismic deformation using continuous time-series data ...

Weak upper-mantle base revealed by postseismic deformation of a deep earthquake

Nature, 2023
Mantle viscosity plays a key role in the Earth's internal dynamics and thermal history. Geophysical inferences of the viscosity structure, however, have shown large variability depending on the types of observables used or the assumptions imposed1-3.

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

Earth, 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.

Co- and postseismic slip behaviors extracted from decadal seafloor geodesy after the 2011 Tohoku-oki earthquake

Earth, Planets and Space, 2021
Investigations of the co- and postseismic processes of the 2011 Tohoku-oki earthquake provide essential information on the seismic cycle in the Japan Trench.

Spatiotemporal Evolution of Postseismic Deformation Following the 2001 Mw7.8 Kokoxili, China, Earthquake from 7 Years of Insar Observations

Remote Sensing, 2018
The 2001 Mw7.8 Kokoxili earthquake, which occurred in the north Tibetan Plateau, ruptured ~400 km of the westernmost portion of the Kunlun fault and produced significant time-dependent postseismic deformation over a large area around the rupture zone and

Postseismic deformation induced by brittle rock damage of aftershocks [PDF]

Journal of Geophysical Research: Solid Earth, 2010
Large earthquakes are commonly followed by abundant aftershocks that are densely located around the coseismic rupture zone. Laboratory experiments indicate that “microscopic” brittle rock failures (acoustic emission) are associated collectively with a “macroscopic” damage‐related inelastic relaxation.

Transient Deformation and Stress Patterns Induced by the 2010 Maule Earthquake in the Illapel Segment

Frontiers in Earth Science, 2021
Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental to assess seismic hazard. Here, we use a 3D forward model as well as GPS and seismic data to investigate the transient deformation and Coulomb Failure ...

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.
