Balancing Earth's Deep Carbon Cycle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The deep carbon cycle of the Earth remains poorly understood in spite of its importance to the evolution of our planet. Here we consider estimated carbon fluxes for plume‐related volcanism from the lower mantle as an independent constraint on the deep carbon cycle, avoiding uncertainties regarding high pressure mineralogy.

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

Are Estimates of Lower Continental Crust Bulk Composition Biased Due to Seismic Anisotropy?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Most seismic inferences on the bulk composition of the lower continental crust are based on P‐wave velocities inferred from seismic wide‐angle data, for which the direction of propagation in the target region is sub‐horizontal. Given the likely presence of anisotropy in many parts of the lower continental crust, these estimates could be biased

Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it.

Fine‐Scale Structure and Kinematics of an Active Submarine Strike‐Slip Fault From Micro‐Bathymetric Mapping and Analog Modeling: The North Alfeo Fault Offshore Catania (Eastern Sicily)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Spatial and Temporal Variations in Slip Rate Over Millions of Years on an Extensional Fault System and Implications for Seismic Hazard

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Slip rate is a key input for fault‐based seismic hazard assessment, with temporal and spatial variations in slip rate along and between faults influencing earthquake size and recurrence. Temporal variations in slip rate have been attributed to earthquake clustering and anti‐clustering in tectonically active settings.

A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Consolidated‐Undrained Shear Behavior of Diatomaceous Mudstones: Implications for Submarine Landslides

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Submarine landslides occur globally and have the potential to damage seafloor infrastructure and trigger tsunamis. Recently, diatomaceous weak layers have been hypothesized to play a role in triggering submarine landslides on passive continental margins by generating overpressure.

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Shear‐Wave Splitting Measured for Permanent Reservoir Monitoring Systems: An Example From the Snorre Field

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Microseismic monitoring of offshore CO2$\rm CO_2$ storage projects is likely to include some deployment of offshore sensors. To improve the value proposition of this monitoring infrastructure, it is important to consider what other information can be gained about the CO2$\rm CO_2$ storage complex and the surrounding region.
