Inference of postseismic deformation mechanisms of the 1923 Kanto earthquake
Journal of Geophysical Research: Solid Earth, 2006Coseismic slip associated with the M7.9, 1923 Kanto earthquake is fairly well understood, involving slip of up to 8 m along the Philippine Sea–Honshu interplate boundary under Sagami Bay and its onland extension. Postseismic deformation after the 1923 earthquake, however, is relatively poorly understood.

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.

Postseismic deformation following the 1906 San Francisco earthquake
Journal of Geophysical Research: Solid Earth, 2000We have reevaluated triangulation data from northern California following the 1906 San Francisco earthquake, thereby increasing the temporal and spatial resolution of postseismic deformation following that event. We have calculated uniform shear strain rates and average station velocities at Point Arena using data from 1906–1907, 1929–1930, and 1973 ...

Short‐time postseismic deformation of 2001 Ms8.1 Kunlun (China) earthquake
Concurrency and Computation: Practice and Experience, 2010AbstractAfter the Ms 8.1 Kunlun earthquake, postseismic displacements were resolved with GPS. The observed data showed that there were significant differences between the deformations on the south and the north sides of the Kunlun fault. In addition, it is shown that the direction of deformation on the north side shifted from westward to eastward after

Cataclastic deformation of garnet: a record of synseismic loading and postseismic creep
Journal of Structural Geology, 2002Abstract Microstructural evidence for episodic deformation of the uppermost plastosphere related to failure of the schizosphere in major seismic events has been previously reported from the Sesia Zone, Western Alps, with inferred extraordinarily high stresses and strain rates for the early stages of creep during stress relaxation at temperatures of ...

Decadal Viscoelastic Postseismic Deformation of the 1964 Mw9.2 Alaska Earthquake
Journal of Geophysical Research: Solid Earth, 2020AbstractViscoelastic postseismic deformation after the 1964 Mw9.2 Alaska earthquake extends thousands of kilometers from the rupture region and lasts for decades, providing unique opportunities to better understand the three‐dimensional rheological properties of the Alaska subduction zone.

Postseismic deformation following the 1991 Racha, Georgia earthquake
2010The April 29, 1991 Racha, Georgia Mw=6.9 earthquake was the largest earthquake recorded in the western section of the Greater Caucasus Mountains. Lithospheric deformation following this earthquake was recorded by a network of eight GPS stations. These data were modeled for postseismic deformation with the mechanisms of afterslip and viscoelastic ...

The vertical postseismic deformation following the 2004 Parkfield earthquake
Studies have shown that the postseismic transient following the 2004 Parkfield earthquake is dominated by aftersllip. However, the studies are mainly focus on the horizontal deformation and ignore the vertical deformation. The focus of this study is the postseismic deformion in vertical caused by 2004 event.Weijie Tan, danan dong, junping Chen

Journal of Geophysical Research: Solid Earth, 1983
The principal purpose of this paper is to examine whether movement of matter in a stratified viscoelastic earth can enhance the excitation of the Chandler wobble. We have constructed analytically a two‐layer model consisting of an elastic lithosphere overlying a Maxwell viscoelastic mantle in order to calculate explicitly the temporal evolution of the ...

Far-field postseismic deformation of the 2023 Kahramanmaraş earthquake doublet
On 6 February 2023, a major earthquake doublet (Mw 7.8 and Mw 7.6) ruptured the Anatolian plate boundary system. The first event occurred on the East Anatolian Fault (EAF), the principal plate-boundary zone between the Arabian and Eurasian plates, and the second ruptured the Çardak fault north of the western termination of the EAF.Volkan Özbey +8 more
