Incorporating Seismic Zonation into Earthquake Catalog Declustering

Abstract Seismic hazard assessment relies upon a complete earthquake catalog, necessitating a declustering procedure to filter out dependent aftershocks or foreshocks from the earthquake catalog. Traditional declustering approaches, such as the Gardner-Knopoff approach, utilize magnitude-dependent temporal and spatial windows to distinguish ...

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

Basin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Subsurface Deformation and Recovery From the Ridgecrest Mw 7.1 Earthquake Revealed by P‐Wave Velocity Time‐Lapse Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate co‐ and post‐seismic P‐wave velocity (Vp) changes following the July 2019 Mw 7.1 Ridgecrest strike‐slip earthquake using time‐lapse tomography from 50,345 P‐wave arrivals (2011–2024). Co‐seismically, Vp changes correspond to the volumetric strain change lobes of the earthquake, increasing in compressional zones and decreasing in

A repeating earthquake catalog for the Atacama Segment in North Chile (24.5°S-30.5°S)

Seismica
Repeating earthquakes are close to identical seismic events that recur on the same fault patch with consistent focal mechanisms. They can be used to estimate local fault slip and their magnitude-dependent recurrence intervals can serve to infer patterns

The 2 May 2025 Mw 7.4 Drake Passage Earthquake: Insights Into Tectonics at the Shackleton Fracture Zone–Chilean Trench Transition

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract On 2 May 2025, an Mw 7.4 earthquake occurred ∼120 km off the southern tip of Tierra del Fuego, at the transition of the Shackleton Fracture Zone and the Chile Trench. This event exhibits reverse‐faulting mechanisms with relatively steeply dipping planes and is the largest recorded along this complex plate boundary.

Magnitudes and Rates of Strength‐Drawdown Modulate Injection‐Induced Seismicity

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Accurately forecasting injection‐induced seismicity remains a major challenge that is critically important for energy production and storage as controlling mechanisms are complex and remain opaque. We clarify key processes by following time‐histories of bespoke parameters anticipated to control strength reduction (drawdown) through ...

Patch Interactions on a Heterogeneous Fault Drive Nearby Slow and Fast Earthquakes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Tectonic tremor and repeating/regular earthquakes off Iwate in the shallow Japan Trench occur episodically and in spatially overlapping areas, implying a common aseismic driver. We investigate how small aseismic slip triggers events across multiple slip‐rate regimes using fully dynamic earthquake‐cycle simulations governed by rate‐and‐state ...

The seismicity in the middle section of the Altyn Tagh Fault system revealed by a dense nodal seismic array

Earthquake Research Advances
The left-lateral Altyn Tagh Fault (ATF) system is the northern boundary of the Qinghai-Xizang Plateau, separating the Tarim Basin and the Qaidam Basin.

Constraining Fault Kinematics and India‐Tarim Convergence Partitioning in Southwestern Tibet With Geodetic Block Modeling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract How the convergent strain between the India Plate and the Tarim basin is partitioned by active faults and off‐fault deformation in southwestern Tibet is poorly understood due to limited knowledge of strain localisation and fault kinematics. In this study, we derive high‐resolution velocity fields for the southwestern Tibetan Plateau using both
