Kinematic Representations of Viscoelastic Postseismic Deformation

Earth and Space Science
AbstractFollowing large earthquakes, viscoelastic stress relaxation may contribute to postseismic deformation observed at Earth's surface. Mechanical representations of viscoelastic deformation require a constitutive relationship for the lower crust/upper mantle material where stresses are diffused and, for non‐linear rheologies, knowledge of absolute ...

Global postseismic deformation: Deep earthquakes

Journal of Geophysical Research: Solid Earth, 2000
We study the global viscoelastic deformations associated with a shear dislocation on a fault embedded in a viscoelastic mantle. To address this problem, we extend the theory of the quasi‐static deformations of a Maxwell, spherical, N‐layer incompressible Earth, previously limited to the modeling of the effects of earthquakes occurring only within the ...

Weakness of the Indian Lower Crust Beneath the Himalaya Inferred From Postseismic Deformation of the 2015 Mw 7.8 Gorkha Earthquake

Journal of Geophysical Research: Solid Earth, 2023
The 2015 Mw 7.8 Gorkha (Nepal) earthquake induced prolonged postseismic deformation extending northward beyond the Yarlung Zangbo Suture, which provides unique opportunities to better understand the lithospheric rheology in Himalaya and southern Tibet ...

Postseismic deformation after 2008 Wenchuan Earthquake

Survey Review, 2014
AbstractApparent postseismic deformation was observed after the 2008 Wenchuan earthquake, China. The displacement in the direction normal to the fault decays to nearly zero after 2013, but the significant dextral movement did not decay obviously during our observation of up to May 2013.

The role of rheological heterogeneities in postseismic deformation

2022
<p>Advances in modelling and access to InSAR and GNSS observations have highlighted the role that rheological heterogeneities play in postseismic deformation. Here we discuss three recent studies (Muto et al. 2019, Sambuddha et al. 2022, and Takada et al.

Postseismic Deformation Monitoring With the COSMO/SKYMED Constellation

IEEE Geoscience and Remote Sensing Letters, 2011
COSMO/SKYMED is currently the unique constellation of synthetic aperture radar (SAR) sensors operative, which is also for civilian use. On April 6, 2009, an Mw 6.3 earthquake struck the city of I'Aquila in Central Italy. The constellation acquired data stacks over the hit area at an unprecedented temporal rate.
