Investigating the postseismic deformation of strike-slip earthquakes on the Tibetan Plateau [PDF]
, 2019 InSAR is a useful technique to detect large-scale surface deformation from space. To place constraints on the rheological structure of the lithosphere in the Tibetan Plateau, two strike-slip earthquakes have been investigated. One is the Mw 7.6 Manyi earthquake, which occurred in the north-central Tibetan Plateau.

Coseismic Rupture and Postseismic Afterslip of the 2020 Nima Mw 6.4 Earthquake
Remote SensingOn 22 July 2020, an Mw 6.4 earthquake occurred in Nima County in the Qiangtang Terrane of the central Tibetan Plateau. This event, caused by normal faulting, remains controversial in terms of its rupture process and causative fault due to the complex ...

On the postseismic deformation at Ikuno immediately after the 1984 Yamasaki earthquake.
Journal of Physics of the Earth, 1987 Immediately after the 1984 Yamasaki fault earthquake of M=5.6, remarkable postseismic deformation, represented by an exponential function, was observed at Ikuno in the northwestern part of the Kinki district, southwest Japan. The exceptional amounts of both strain and tilt changes suggest that the local conditions of the observation site played an ...

Sub-parallel fault afterslip and weak zone relaxation after the 2024 Noto earthquake
Communications Earth & EnvironmentPostseismic deformation carries valuable information about the complex fault system and deep rheological structure. We analyzed ~6 months of postseismic deformation following the 2024 moment magnitude 7.5 Noto earthquake using InSAR and GNSS data ...

Weak asthenosphere of Sumatran backarc revealed by long postseismic geodetic records
Communications Earth & EnvironmentThe viscosity of Earth’s asthenosphere regulates plate motion and surface deformation. Assessing asthenosphere rheology in subduction-zone backarcs is as crucial as in forearc and arc regions for understanding subduction dynamics.

Postseismic deformation following the 1991 Racha, Georgia, earthquake [PDF]
Geophysical Research Letters, 2007 The 1991, Ms = 7.0 Racha earthquake is the largest ever recorded in the Caucasus Mountains. Approximately three months after this thrust‐faulting earthquake, a GPS network was set up to measure postseismic surface deformation. We present an analysis of these data, which indicate accelerated postseismic motions at several near‐field sites. We model this

Modeling the Contribution of Poroelastic Deformation to Postseismic Geodetic Signals
Geophysical Research Letters, 2020 AbstractTo constrain the poroelastic component of postseismic deformation, we model the subsurface hydrologic response to the Mw 7.6 subduction zone earthquake that occurred on the plate interface beneath the Nicoya peninsula in Costa Rica on 5 September 2012. The model shows that poroelastic relaxation occurs on multiple time scales and the associated
