Mainshock‐Induced Stress Changes Modulate Initial Aftershocks on Complex Branching Faults of the 2019 Ridgecrest Earthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Large earthquakes can activate complex aftershock fault networks. In such systems, what controls the spatiotemporal evolution of early aftershocks remains a critical yet unresolved problem. Here, using the 2019 M 7.1 Ridgecrest earthquake as an example, we partition the first 10 days of aftershocks onto 15 branching faults activated by the ...

Thermally Activated Static Friction Can Explain Earthquake Interactions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

Significant afterslip contribution to postseismic deformation in Sado Island following the 2024 Noto Peninsula earthquake: insights from two dense GNSS observation networks

Earth, Planets and Space
This study investigated postseismic deformation resulting from the 2024 Noto Peninsula earthquake on January 1. Particular focus was placed on the displacement observed in Sado Island, which is located several tens of kilometers east of the eastern end ...

Deformation and Earthquake Potential on the North America–Caribbean–Cocos Plate Boundary System in Guatemala

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In Guatemala, the Cocos, North American, and Caribbean plates interact to create a region of high seismic risk. Previous analyses of crustal faults in the country have been overly simplified, creating discrepancies between geologic and geodetic slip rate models.

Fine‐Scale Segmentation and Spatiotemporal Variability of the 2010 Mw 8.8 Maule Aftershock Sequence Revealed by a Deep‐Learning‐Based Earthquake Catalog

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We re‐examine the aftershock sequence of the Mw 8.8 Maule earthquake in south‐central Chile to understand how seismicity, magnitude‐frequency distribution, and fault structure vary along the rupture zone. Using the International Maule Aftershock Deployment (IMAD) data set, we analyze 10 months of continuous data from approximately 156 ...

Time-dependent distributed afterslip on and deep below the Izmit earthquake rupture

Bulletin of the Seismological Society of America, 2002
Surface deformation transients measured with the Global Positioning System during the 87 days between the 17 August 1999 Izmit earthquake and the 12 November 1999 Duzce earthquake indicate rapidly decaying aseismic fault slip on and well below the coseismic rupture.

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating links among slow earthquakes, megathrust events, and complex subduction structures.

Rheological and tectonic implications of eastern Tibet: Insights from early aftershock sequences driven by afterslip following three 2021–2022 moderate-large events

International Journal of Applied Earth Observations and Geoinformation
Early aftershock sequences and afterslip provide key insights into crust rheology and the triggering mechanisms of seismicity sequences. Three recent moderate-large strike-slip earthquakes in eastern Tibet, including the 2021 Yangbi Mw 6.1, the 2021 ...

Probing time-dependent afterslip and viscoelastic relaxation following the 2015 Mw7.8 Gorkha earthquake based on the 3-D finite-element model

Earth, Planets and Space, 2020
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha earthquake.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor
