Heterogeneous rheology controlled postseismic deformation of the 2011 Tohoku‐Oki earthquake [PDF]

Geophysical Research Letters, 2016
Using two‐dimensional finite element modeling, we reproduced the observed postseismic deformation of the 2011 Tohoku‐Oki earthquake. Our model, which accounts for the lithosphere‐asthenosphere boundary and weak zones beneath volcanoes, was able to ...

Overlapped Postseismic Deformation Caused by Afterslip and Viscoelastic Relaxation Following the 2015 Mw 7.8 Gorkha (Nepal) Earthquake

Journal of Geophysical Research: Solid Earth, 2021
Studying transient postseismic deformation is one of the key approaches to probe fault kinematics and rheological behavior of rocks surrounding tectonic faults.

Vertical Postseismic Deformation of the 2019 Ridgecrest Earthquake Sequence

Journal of Geophysical Research: Solid Earth, 2022
The 2019 Ridgecrest conjugate Mw6.4 and Mw7.1 events resulted in several meters of strike‐slip and dip‐slip along an intricate rupture, extending from the surface down to 15 km.

Izmit earthquake postseismic deformation and dynamics of the North Anatolian Fault Zone [PDF]

Journal of Geophysical Research: Solid Earth, 2009
We have modeled postseismic deformation from 1999 to 2003 in the region surrounding the 1999 Izmit and Düzce earthquake ruptures, using a three‐dimensional viscoelastic finite element method. Our models confirm earlier findings that surface deformation within the first few months of the Izmit earthquake is principally due to stable frictional afterslip

Modeling the Contribution of Poroelastic Deformation to Postseismic Geodetic Signals

Geophysical Research Letters, 2020
AbstractTo constrain the poroelastic component of postseismic deformation, we model the subsurface hydrologic response to the Mw 7.6 subduction zone earthquake that occurred on the plate interface beneath the Nicoya peninsula in Costa Rica on 5 September 2012. The model shows that poroelastic relaxation occurs on multiple time scales and the associated

Spatiotemporal functional modeling of postseismic deformations after the 2011 Tohoku-Oki earthquake [PDF]

Earth, Planets and Space, 2022
Postseismic deformations continue to occur for a long period after major earthquakes. Temporal changes in postseismic deformations can be approximated using simple functions.

Coseismic and Postseismic Deformations of the 2023 Turkey Earthquake Doublet

Remote Sensing
On 6 February 2023, an earthquake doublet of Mw 7.8 and Mw 7.5 occurred in southeastern Turkey and caused surface ruptures over 350 km for the eastern Anatolian fault (EAF) and 150 km for the Surgu fault (SF), respectively. Over 3700 Mw > 3.0 aftershocks

Coseismic Slip and Early Postseismic Deformation Characteristics of the 2025 Mw 7.0 Dingri Earthquake

Remote Sensing
On 7 January 2025, an Mw 7.0 earthquake struck Dingri County, Shigatse, Tibet. This was the largest event in the region in recent years. Analysis of the Dingri earthquake is urgent for understanding the coseismic slip and early postseismic deformation ...

Gravity-driven postseismic deformation following the Mw 6.3 2009 L'Aquila (Italy) earthquake. [PDF]

Sci Rep, 2015
AbstractThe present work focuses on the postseismic deformation observed in the region of L’Aquila (central Italy) following the Mw 6.3 earthquake that occurred on April 6, 2009. A new, 16-month-long dataset of COSMO-SkyMed SAR images was analysed using the Persistent Scatterer Pairs interferometric technique.

Influences of the heterogeneity of viscoelastic medium on postseismic deformation of the 2008 MW7.9 Wenchuan earthquake

Geodesy and Geodynamics, 2022
The study of postseismic deformation is important for constraining the viscoelastic properties of the Earth and inverting the post-earthquake process. The levelling survey revealed that the area near Beichuan elevated 5.3 cm about two years after the MW7.
