Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Studies of small earthquake (M < 2) rupture processes traditionally rely on simplified models that assume symmetric slip or point sources. Using an exceptionally dense seismic network and empirical Green's function (EGF) analysis, we investigate the complex rupture of a Mw 1.6 microearthquake induced by hydraulic fracturing.

Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

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

open access: yesGeophysical 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

open access: yesGeophysical 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.

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 ...
