Role of Slabs in Postseismic Deformation Following Deep Earthquakes

Journal of Geophysical Research: Solid Earth
Abstract The Earth's viscoelastic postseismic deformation reflects its rheological structure. Even though low‐viscosity structures, such as the asthenosphere, are often thought to dominate postseismic deformation induced by shallow earthquakes, high‐viscosity subducting slabs have also been found to considerably affect postseismic ...

A 3D finite-element mesh for modeling large-scale surface deformation induced by subduction megathrust earthquakes: Application to Chile

Seismica
Megaearthquakes (Mw > 8) cause continental-scale, long-lasting surface deformation, mainly due to viscoelastic relaxation of the asthenosphere. To investigate the links between this deformation and the slip history along subduction interfaces—including ...

Postseismic deformation due to subcrustal viscoelastic relaxation following dip‐slip earthquakes [PDF]

Journal of Geophysical Research: Solid Earth, 1984
The deformation of the earth following a dip‐slip earthquake is calculated by using a three‐layer rheological model and finite element techniques. The three layers are an elastic upper lithosphere, a standard linear solid lower lithosphere, and a Maxwell viscoelastic asthenosphere. Attention is focused on the magnitude of the postseismic subsidence and

MODELLING OF POSTSEISMIC PROCESSES IN SUBDUCTION ZONES

Геодинамика и тектонофизика, 2015
Large intraplate subduction earthquakes are generally accompanied by prolonged and intense postseismic anomalies. In the present work, viscoelastic relaxation in the upper mantle and the asthenosphere is considered as a main mechanism responsible for the

Coseismic Slip and Early Postseismic Deformation Characteristics of the 2025 Mw 7.0 Dingri Earthquake

Remote Sensing
On 7 January 2025, an Mw 7.0 earthquake struck Dingri County, Shigatse, Tibet. This was the largest event in the region in recent years. Analysis of the Dingri earthquake is urgent for understanding the coseismic slip and early postseismic deformation ...

Coseismic Rupture and Postseismic Afterslip of the 2020 Nima Mw 6.4 Earthquake

Remote Sensing
On 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 ...

Sub-parallel fault afterslip and weak zone relaxation after the 2024 Noto earthquake

Communications Earth & Environment
Postseismic 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 ...
