Kinematic Representations of Viscoelastic Postseismic Deformation [PDF]
Earth and Space ScienceAbstractFollowing 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 ...

Postseismic deformation following the 2016 Kumamoto earthquake detected by ALOS-2/PALSAR-2 [PDF]
Earth, Planets and Space, 2020 I have been conducting a study of postseismic deformation following the 2016 Kumamoto earthquake using ALOS-2/PALSAR-2 acquired till 2018. I apply ionospheric correction to interferograms of ALOS-2/PALSAR-2.

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

Pore-pressure diffusion controls upper-plate aftershocks of the 2014 Iquique earthquake [PDF]
Nature CommunicationsUpper-plate aftershocks following megathrust earthquakes are particularly dangerous as they may occur close to densely populated regions. Aftershock numbers decay with time, imposing a time-dependent seismic hazard that is assessed with statistical ...

Omori‐like decay of postseismic velocities following continental earthquakes [PDF]
Geophysical Research Letters, 2017 Various mechanisms have been proposed to explain the transient, enhanced surface deformation rates following earthquakes. Unfortunately, these different mechanisms can produce very similar surface deformation patterns leading to difficulty in ...

A viscoelastic and afterslip postseismic deformation model for the 1964 Alaska earthquake [PDF]
Journal of Geophysical Research: Solid Earth, 2009 We developed a 3‐D viscoelastic model, in concert with an afterslip model, to describe the postseismic deformation following the 1964 Alaska earthquake. Our model incorporates a realistic geometry including an elastic slab with very low dip angle. These geometric factors are important and require a reanalysis of the 1964 coseismic model.

Geodesy and Geodynamics, 2016 On 3 July 2015, a Mw 6.4 earthquake occurred on a blind fault struck Pishan, Xinjiang, China. By combining Crustal Movement Observation Network of China (CMONOC) and other Static Global Positioning System (GPS) sites surrounding Pishan region, it ...

On the effects of thermally weakened ductile shear zones on postseismic deformation [PDF]
Journal of Geophysical Research: Solid Earth, 2013 We present three‐dimensional (3‐D) numerical models of postseismic deformation following repeated earthquakes on a vertical strike‐slip fault. Our models use linear Maxwell, Burgers, and temperature‐dependent power law rheology for the lower crust and upper mantle.

A note on the assumptions made while computing the postseismic lithospheric deformation
Journal of Earth System Science, 1997 The postseismic lithospheric deformation is usually explained as viscoelastic relaxation of the coseismic stresses. In general, for computing the postseismic deformation, the shear modulus (μ) is relaxed, keeping either the bulk modulus (k) or the La’me parameter (A) fixed. It is shown that the two assumptions yield significantly different results. The

Coseismic and Postseismic Deformations of the 2023 Turkey Earthquake Doublet
Remote SensingOn 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
