Three-dimensional tomographic inversion of combined reflection and refraction seismic travel-time data

, 2003
A tomographic inversion method is presented for the determination of 3-D velocity and interface structure from a wide range of body-wave seismic traveltime data types.

Collocated Geotechnical and Geophysical Test Dataset at Three Sites in Napier, New Zealand

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods.

The Cenozoic basins of Sardinia (Italy) and their Late Miocene to Present inversion: insight from new seismic data

BSGF - Earth Sciences Bulletin
This study aims to discuss the history and significance of the Cenozoic basins in Sardinia, both before and after the rotation of the Corsica-Sardinia Block, within the Western Mediterranean geodynamic framework, taking into account new seismic data.

Revisions to the 2023 U.S. 50‐State National Seismic Hazard Model

Earthquake Spectra, Volume 42, Issue 4, November 2026.
We present an update to the 2023 U.S. 50‐state National Seismic Hazard Model, based on questions and comments received from a range of users, as well as additional internal and building code reviews since its initial release. For the conterminous United States, the update includes (1) revised weighting of ground motion models in the Intermountain West,

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.

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

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Modulation of Slow Slip Event Characteristics Throughout the Costa Rica Subduction Zone Earthquake Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

A Unified Quadratic Scaling Relation Between Potency and Local Earthquake Magnitudes for −1.8 ≤ ML ≤ 7.5

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Quantifying earthquake size across scales requires linking physical source parameters to empirical magnitude measures, especially for microearthquakes where attenuation, scattering, and instrumental limitations complicate source characterization.

The walls boundary fault zone and the MØre TrØndelag fault complex:: a case study of two reactivated fault zones. [PDF]

, 2001
It is commonly observed that ancient faults or shear zones can become reactivated again and again, either within the same or even superimposed tectonic episodes, yet millions of years apart.
