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 ...

Afterslip and slow slip events in the postseismic deformation of the 2016 Pedernales earthquake, Ecuador

, 2020
International audienceIn subduction zones, slip along the plate interface occurs in various modes including earthquakes, steady slip, and transient accelerated aseismic slip during either Slow Slip Events (SSE) or afterslip.

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

Recent GPS-based long wavelength crustal deformation revealed active postseismic deformation due to the 2006 Yogyakarta earthquake

, 2022
We analyze the Global Positioning System (GPS)-derived strain rate distribution to investigate active crustal structure in Central Java, Indonesia, using ten years (2010-2019) continuous and permanent observation data.

Postseismic deformation and body forces shaping the Apennines and adjacent sedimentary basins in Umbria-Marche

, 2008
The geodynamic complexity of the Apennines and adjacent sedimentary basins in Umbria-Marche (North-Central Italy) makes the dynamics of the present day deformation and its relationships with the seismicity less well understood.

Using Heterogeneous 3D Earth Models to Constrain Interseismic and Postseismic Deformation in Southern California and Nepal [PDF]

, 2018
We characterize interseismic strain accumulation across the Los Angeles basin and postseismic deformation following the 2010 Mw=7.2 El Mayor-Cucapah and 2015 Mw=7.8 Nepal earthquakes using geodetic data.

Postseismic deformation following the 1991 Racha, Georgia earthquake

, 2006
The 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.

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 ...

Postseismic deformation mechanisms of the 1990 Mw 6.4 Gonghe, China earthquake constrained using leveling measurements

, 2012
We model leveling deformation data observed following the 1990 Mw 6.4 Gonghe earthquake in Qinghai province, western China, to infer postseismic deformation sources and mechanisms. Using coseismic vertical displacements and previous study result obtained
