Interplay of Tectonics and Topography Facilitated Sudden Dyke Intrusion in 2022 at São Jorge Island, Azores

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Oblique slow rifting in a hotspot setting has created a distributed volcanic zone in the central part of the Azores but it's unclear what causes focusing of magma upflow under the islands within a wide plate boundary deformation zone. For São Jorge Island, we use a three‐dimensional finite element model to evaluate crustal stress from the ...

Teleseismic Radial Anisotropy Reveals a Sill‐Dominated Magma Reservoir Beneath the Valles Caldera, New Mexico

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Valles Caldera (VC), one of the largest Quaternary silicic calderas in North America, formed by explosive rhyolitic eruptions. Seismic studies suggest a crustal magmatic reservoir beneath the caldera with low‐velocity anomalies, but resolving the detailed geometry of localized melt requires constraints from seismic anisotropy.

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...
