Spatiotemporal functional modeling of postseismic deformations after the 2011 Tohoku-Oki earthquake [PDF]
Earth, Planets and Space, 2021 Abstract Postseismic deformations continue to occur for a long period after major earthquakes. Temporal changes in postseismic deformations can be approximated using simple functions. Since the 2011 Tohoku-Oki earthquake, operating global navigation satellite system stations have been continuously accumulating a remarkable amount of ...

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

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.

Weak upper-mantle base revealed by postseismic deformation of a deep earthquake
Nature, 2023 Mantle viscosity plays a key role in the Earth's internal dynamics and thermal history. Geophysical inferences of the viscosity structure, however, have shown large variability depending on the types of observables used or the assumptions imposed1-3.

Earth, Planets and Space, 2020 We infer the postseismic deformation mechanisms following the 2011 Tohoku megathrust earthquake via an analysis of onshore geodetic observations. We focus on the temporal decay characteristics of postseismic deformation using continuous time-series data ...

Omori‐like decay of postseismic velocities following continental earthquakes
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 ...

Postseismic deformation induced by brittle rock damage of aftershocks [PDF]
Journal of Geophysical Research: Solid Earth, 2010 Large earthquakes are commonly followed by abundant aftershocks that are densely located around the coseismic rupture zone. Laboratory experiments indicate that “microscopic” brittle rock failures (acoustic emission) are associated collectively with a “macroscopic” damage‐related inelastic relaxation.
