Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Tidal Heating in a Subsurface Magma Ocean on Io Revisited

Geophysical Research Letters
We investigate the tidal dissipation in Io's hypothetical fluid magma ocean using a new approach based on the solution of the 3D Navier‐Stokes equations.

Generation and Dissipation of Infragravity Waves Over Natural and Engineered Chenier Plain During Hurricane Laura

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Infragravity (IG) waves play a crucial role in nearshore hydrodynamics and sediment transport; however, their generation and dissipation mechanisms during extreme storms remain challenging to assess due to limited data availability, site‐specific characteristics of natural landscapes, and anthropogenic effects.

Amplifying Resonant Repulsion with Inflated Young Planets, Overlooked Inner Planets, and Nonzero Initial Δ

The Astrophysical Journal
Most multiplanet systems around mature (∼5 Gyr old) host stars are nonresonant. Even the near-resonant planet pairs still display 1%–2% positive deviation from perfect period commensurabilities (Δ) near first-order mean motion resonances (MMRs). Resonant

A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.

A Sea‐Ice‐Enhanced KPP Parameterization: Impacts on AMOC Simulation and Physical Pathways

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract This study presents a sea‐ice‐enhanced K‐profile parameterization to improve simulations of the Atlantic Meridional Overturning Circulation (AMOC) in ocean–sea ice coupled models. The modified KPP dynamically scales the background vertical diffusivity with local sea‐ice fraction, representing the insulating and turbulence‐suppressing effects ...

Non‐Migrating Thermal Tides in the Martian Lower Atmosphere Observed by EMM/EMIRS

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Thermal tides significantly influence Martian atmospheric dynamics and radiative transfer. However, the excitation mechanisms of non‐migrating tides, exhibiting diverse spatial structures, remain poorly understood due to the limited number of observations.

Submesoscale Energy Cycle in a Coupled Ocean‐Atmosphere Simulation of the Gulf Stream

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the Gulf Stream energy cycle, with emphasis on the submesoscale pathway relative to other energy sinks. Using a high‐resolution coupled air–sea simulation (CROCO–WRF), we construct a Lorenz diagram based on temporally and spatially separated submesoscale and background energy budgets.

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Potential Melting of Extrasolar Planets by Tidal Dissipation

The Astrophysical Journal
Tidal heating on Io due to its finite eccentricity was predicted to drive surface volcanic activity, which was subsequently confirmed by the Voyager spacecraft.
