The Role of Fluids in Fault Mechanics: A 16‐Year Analysis of the Irpinia Seismicity (Southern Italy)

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Fluids in the crust influence earthquake nucleation by affecting fault strength and rupture dynamics, but direct observations at seismogenic depths are rare. We study the Irpinia Fault System in Southern Italy, site of the 1980 M 6.9 earthquake, to understand how fluid overpressure, fault orientation, and regional stress control earthquake ...

Validation of 1‐Day Repeat SWOT Measurements Against Tide‐Gauge and Glider Data Off Canada's West Coast

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite observations are shown to agree well with tide gauge and underwater glider data in the Northeast Pacific. The SWOT mission measures sea surface height in a 120‐km wide swath. It had a 1‐day repeat cycle for 3 months in 2023.

Fault Kinematic Controls on the Spatio‐Temporal Proximity of the 2023 Mw 7.8‐7.7 Türkiye Earthquakes

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The mechanism governing the spatio‐temporal proximity of the 2023 Mw 7.8‐7.7 Türkiye earthquakes remains enigmatic. Here, we used dense geodetic observations integrated with dual‐fault screw dislocation, Euler‐vector‐constrained block, and strain‐rate models to investigate the interseismic kinematics and pre‐stress state of the East Anatolian ...

Mesoscale Eddy Currents Reshape the Spatial Distribution of Wave Height in the Southern Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale eddy currents influence ocean surface waves, but their imprints on wave height remain poorly described by observations. Here, we examine significant wave height (SWH) variations associated with more than 42,000 mesoscale eddies in the Southern Ocean using along‐track Jason‐3 altimeter measurements.

Characteristics of Seismic Energy Rate Functions of Shallow Tremors

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...
