Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Geodetic Constraints on the Crustal Deformation along the Kunlun Fault and Its Tectonic Implications

Remote Sensing, 2019
This study focuses on the crustal deformation and interseismic fault coupling along the strike-slip Kunlun fault, northern Tibet, whose western segment ruptured in the 2001 Mw 7.8 Kokoxili earthquake.

The Role of Normal Stress and Shear Stress Heterogeneity in the Inferred Depth‐Independence of Stress Drop

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquake stress drops are inferred to be independent of source depth, contradicting linear scaling predictions for earthquakes as frictional stick‐slip instabilities that assume increasing fault normal stress due to overburden. Here, we examine the scaling between averaged stress drops and increasing normal stress for simulated earthquake ...

Pseudotachylyte Formation in Brittle–Ductile Transition of the Anning River Fault Zone: Implications for Seismic Processes

Applied Sciences
Pseudotachylytes and cataclasites record transient seismic slips within the brittle–ductile transition zone and ductile flow layers. Investigating the mechanisms of pseudotachylytes can provide the most direct geological evidence for revealing seismic ...

Geodetic and geological investigation of interseismic deformation onshore Paliki peninsula, Cephalonia, Greece

, 2023
We present a comprehensive analysis of geodetic data, including InSAR imagery and GNSS observations, to assess the pattern of ground motions of the Paliki peninsula in western Cephalonia, Greece. Paliki is prone to frequent, strong earthquakes, due to its close proximity to the right-lateral Cephalonia Transform Fault (CTF), a 140 km long strike-slip ...

Coulomb Pre‐Stress Changes Modulate Coseismic Rupture Kinematics of the 2025 Mw7.7 Myanmar Earthquake Revealed by Space Geodesy

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract We estimate the fault geometry and coseismic slip of the 2025 Myanmar earthquake using multi‐source satellite observations, revealing a nine‐segment rupture structure that transitions from eastward‐dipping in the north to westward‐dipping in the south, with peak slip of ∼6 m and negligible shallow slip deficit.

Goce derived geoid changes before the Pisagua 2014 earthquake

Geodesy and Geodynamics, 2018
The analysis of space – time surface deformation during earthquakes reveals the variable state of stress that occurs at deep crustal levels, and this information can be used to better understand the seismic cycle.

Tectonics as a Regulator of Shoreline Retreat and Rocky Coast Evolution Across Timescales

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Rocky coast morphology is shaped by interactions between wave action, sea level, and tectonics over millennial time scales. However, a clear and quantifiable signature of tectonic uplift on decadal to centennial shoreline retreat rates is outstanding.

Interplay Between Tectonics and Submarine Mass Transport Deposits in Cortes Basin: New High‐Resolution Geophysics in the Outer California Borderland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Outer California Borderland (OCB) is an active transform plate boundary offshore Southern California, where the relationship between faulting and submarine mass transport deposits (MTDs) remains poorly understood. Onshore paleoseismic data provide high‐resolution earthquake records, whereas marine geophysical data capture longer‐term ...
