Models of stress at mid-ocean ridges and their offsets [PDF]

, 2000
This thesis aims to investigate the stresses at mid-ocean ridge offsets, and particularly at the particular class of offsets represented by oceanic microplates. Amongthese, the Easter microplate is one of the best surveyed.

OBS Data Mining Reveals Seismic Structure and Dynamics of the Oceanic Blanco Transform Fault, Northeast Pacific

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Deformation along oceanic transform faults is partitioned between seismic and aseismic slip, controlled by lithology, thermal structure, and fluid circulation. We analyze one year of data from a 54‐station ocean bottom seismometer network deployed across the Blanco Transform Fault (BTF), Northeast Pacific.

Late Mesozoic mafic magmatism from the North China Block: constraints on chemical and isotopic heterogeneity of the subcontinental lithospheric mantle

, 2005
Available major, trace element and Sr-Nd isotope data for the late Mesozoic mafic rocks in the eastern North China Block (NCB) show chemical and isotopic differences between rocks from different tectonic units.

A numerical study of the dynamics of subduction [PDF]

, 1988
The mechanics and dynamics of subduction have been studied using 2-D finite element analysis. Two finite element formulations have been employed; one formulation for Newtonian viscous flow and one formulation for linear elasticity and viscoelasticity ...

Heterogeneous Earth’s mantle drilled at an embryonic ocean

Nature Communications
Mantle processes control plate tectonics and exert an influence on biogeochemical cycles. However, the proportion of mantle sampled in-situ is minimal, as it is buried beneath igneous crust and sediments.

Complex Shear‐Wave Splitting Behavior in the Northern Andes and Possible Implications for Mantle Flow Around the Caldas Tear

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Validating SCUBAS Predictions of Geomagnetically Induced Voltage in Submarine Cables Using Legacy Superstorm Observations

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Modern submarine communication cables, though fiber‐optic in nature, remain vulnerable to space weather hazards due to their internal conductive cables used for powering repeaters. During geomagnetic storms, variations in the geomagnetic field induce geoelectric fields that drive geomagnetically induced voltages along these cables.

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling

, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...

Foreland Flexure and Lower Crustal Flow as Controls on Cenozoic Subsidence Anomalies in the Zengmu (Sarawak) Basin, South China Sea

Tectonics, Volume 45, Issue 6, June 2026.
Abstract While the evolution of individual passive marginal and foreland basins is well understood, the subsidence pattern of passive margins near convergence zones—where thrust loading overprints earlier extension and the typical wedge and foredeep are obscured—remains poorly understood.

Age-dependent seismic thickness and mechanical strength of the Australian lithosphere

, 2002
We present constraints on the regional variations of the seismic and mechanical thickness of the Australian lithosphere. We infer the seismic thickness from a waveform tomographic model of S-wave speed, and as a proxy for the elastic thickness we use the
