Stress Barriers and Their Impact on Rupture Propagation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Earthquake ruptures often exhibit complex behaviors, including abrupt arrest followed by delayed re‐nucleation. While on‐fault stress heterogeneity is a recognized contributing factor, as it can arrest or slow down rupture propagation, its interaction with propagating ruptures remains complex and not fully understood. Here, we study frictional

Seismic Velocity Variations, Ground Deformation and the Role of Fluids During a Low‐Energy Seismic Swarm

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On March 9th $9\mathrm{th}$, 2023, three small earthquakes (3.8≤Mw≤4.5) $(3.8\le {M}_{w}\le 4.5)$ occurred near Umbertide (Central Italy), within 4 hours. Analyzing seismic ambient noise in the frequency band 0.1–1 Hz from six seismometers within 20 km of the Mw 4.5, we detect a significant drop in seismic velocity at the time of occurrence of

Kinematic GNSS inversion of the large afterslip (Mw 6.4) following the 2019 Mw 6.2 Hualien earthquake (Taiwan)

Frontiers in Earth Science
The postseismic deformation following the April 2019 Mw 6.2 Hualien earthquake presents an unique opportunity to investigate the mechanisms by which the northern section of the Longitudinal Valley accommodates lithospheric deformation.

Rupture Dynamics of the 2025 Mw 7.7 Myanmar Earthquake: A Bilateral Supershear Rupture on Unusually Long Fault Superhighway

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The 2025 Mw 7.7 Myanmar earthquake ruptured the central Sagaing fault, a previously identified seismic gap with high seismic potential. Here, we perform hundreds of 3D dynamic rupture simulations to investigate the rupture dynamics, constrained by near‐fault strong‐motion waveforms, optical and SAR pixel offsets, and a kinematic source model ...

Seismogenic Thickening in the Pamir Plateau From Craton Underthrusting Revealed by the 2023 Mw 6.9 Earthquake

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The convergence of the Indian and Eurasian plates beneath the Pamir Plateau has produced complex continental subduction, significantly influencing upper crustal faulting and seismicity. To investigate the kinematic behavior of the High Pamir Plateau, we derive a geodetic slip model for the 2023 Mw 6.9 Pamir earthquake by using Sentinel‐1A and ...

Coseismic Slip and Early Afterslip of the 2024 Hyuganada Earthquake Modulated by a Subducted Seamount

Geophysical Research Letters
Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction.

Afterslip and viscoelastic relaxation following the 1999M7.4 İzmit earthquake from GPS measurements [PDF]

Geophysical Journal International, 2009
SUMMARY Intensive global positioning system (GPS) monitoring after the 1999 Izmit earthquake provides an opportunity to understand the postseismic behaviour of a strike-slip fault and the rheology below the brittle upper crust. Two data sets are available: displacements measured during the first 300 days after the Izmit earthquake and velocity ...

High‐Density Seismic Network for Improved Tomographic Imaging of the Ecuadorian Forearc: Slip Mode Controlled by In Situ Material Heterogeneity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Large subduction earthquakes often occur along the Ecuadorian margin. Following the 2016 Pedernales megathrust earthquake (Mw 7.8), a temporary network of 82 stations recorded its aftershocks. Data from this international response and the permanent network run by IG‐EPN showed that subducted seafloor topography, accreted terranes, and ...

Seismic‐afterslip characterization of the 2010 MW 8.8 Maule, Chile, earthquake based on moment tensor inversion

Geophysical Research Letters, 2012
On February 27th 2010, a MW8.8 earthquake struck the coast of south‐central Chile, rupturing ∼500 km along the subduction interface. Here we estimate the amount of seismically‐released afterslip (SRA) and the mechanisms underlying the distribution of ...

Imaging rapid early afterslip of the 2016 Pedernales earthquake, Ecuador

Earth and Planetary Science Letters, 2019
High-Rate (HR) GPS time series following the 2016 Mw 7.8 Pedernales earthquake suggest significant postseismic deformation occurring in the early postseismic period (i.e. first few hours after the earthquake) that is not resolved with daily GPS time series.
