Decomposition of Postseismic Signals Following ≥Mw 6 Earthquakes on Sumatra Island Based on Sumatran GPS Array (SuGAr) Observations

Journal of Geospatial Information Science and Engineering
Indonesia, located at the convergence of four major tectonic plates, experiences frequent large earthquakes, particularly in Sumatra, due to the subduction of the Indo-Australian Plate and the Sumatra Fault Zone (SFZ).

How Long Can the Postseismic and Interseismic Phases of Great Subduction Earthquake Sustain? Toward an Integrated Earthquake‐Cycle Perspective

Geophysical Research Letters, 2023
The transition of subduction systems from postseismic to interseismic phase is an important indicator of their stress state and readiness for subsequent events.

Geodetic Resolution of the Interplay Between Earthquakes and Slow Slip in the Hikurangi Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Interactions between slow slip and earthquakes remain poorly understood. We examine such an interaction in the central Hikurangi subduction zone where several moderate (Mw 4–5+) earthquakes occurred during a deep, 2‐year M7 slow slip event that started in 2021.

Fault Kinematic Controls on the Spatio‐Temporal Proximity of the 2023 Mw 7.8‐7.7 Türkiye Earthquakes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The mechanism governing the spatio‐temporal proximity of the 2023 Mw 7.8‐7.7 Türkiye earthquakes remains enigmatic. Here, we used dense geodetic observations integrated with dual‐fault screw dislocation, Euler‐vector‐constrained block, and strain‐rate models to investigate the interseismic kinematics and pre‐stress state of the East Anatolian ...

Homogeneous vs heterogeneous subduction zone models: Coseismic and postseismic deformation [PDF]

, 2001
A finite-element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic half-spaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic ...

Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...

Rapid early afterslip characteristics of the 2010 moment magnitude (Mw) 8.8 Maule earthquake determined with sub-daily GPS solutions

Satellite Navigation
Ground surface deformations can be observed during the coseismic and postseismic periods. The accurate determination of displacements is of paramount importance for the assessment of the destructive power of large earthquakes and the characterization of ...

Stress Transfer From Slow Slip Events to Earthquake Swarms as a Cycle in the Southernmost Ryukyu Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Poroelastic effects associated with earthquakes on overpressured reverse and normal faults

Frontiers in Earth Science
Earthquakes in fluid-saturated rocks induce sudden changes in pore-pressures that can lead to appreciable postseismic deformation. However, earthquakes can also release fluids from overpressured parts of the crust, which can also contribute to additional

Present-day crustal deformation revealed active tectonics in Yogyakarta, Indonesia inferred from GPS observations

Geodesy and Geodynamics, 2020
We investigated the active crustal structure in Yogyakarta, Indonesia, using new and denser Global Positioning System (GPS) data. Deformation rate estimated from five years (2013–2018) of observations on 22 campaign might record broad deformation after ...
