InSAR Postseismic Displacements of the 2023 Turkey Earthquakes
The two major earthquakes (magnitude 7.8 and 7.6) in southeastern Turkey in 2023 resulted in a combined fault rupture length of 500 km. The events were driven by the northward motion of the Arabian Plate colliding with the Eurasian Plate and the westward escape of the Anatolian Plate.

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.

Spatial–temporal properties of afterslip associated with the 2015 Mw 8.3 Illapel earthquake, Chile
Earth, Planets and Space, 2021 In order to characterize the spatial–temporal properties of postseismic slip motions associated with the 2015 Illapel earthquake, the daily position time series of 13 GNSS sites situated at the near-field region are utilized.

Coseismic and postseismic fault slip characteristics of the 2020 MW6.3 Nima earthquake
地球与行星物理论评, 2023 The 2020 MW6.3 Nima earthquake occurred in the northern Yibug Caka graben on the Qiangtang Block of the Tibetan Plateau. The epicentral area has complex geological structures, topography, and geomorphology, and there are few near-field ground observation

Postseismic relaxation and transient creep [PDF]
Journal of Geophysical Research: Solid Earth, 2005 Postseismic deformation has been observed in the epicentral area following the 1992 Landers (M = 7.3), 1999 Chi‐Chi (M = 7.6), 1999 Hector Mine (M = 7.1), 2002 Denali (M = 7.9), 2003 San Simeon (M = 6.5), and 2004 Parkfield (M = 6.0) earthquakes. The observations consist of repeated GPS measurements of the position of one monument relative to another ...

Postseismic response of repeating aftershocks [PDF]
Geophysical Research Letters, 1998 The recurrence intervals of repeating earthquakes on the San Andreas Fault in the Loma Prieta aftershock zone follow the characteristic 1/t decay of Omori's law. A model in which these earthquakes occur on isolated patches of the fault that fail in stick‐slip with creep around them can explain this observation.

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.
