Reappraisal of Holocene Caldera Resurgence at Campi Flegrei (Southern Italy): A Long‐Lived Magma‐Driven Resurgent Dome System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Bayesian Inference of Fault Slip Heterogeneity and Overlap: Application to 2019 Ridgecrest Earthquakes and Afterslip

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Fault slip occurs in both seismic and aseismic styles with spatial variability across scales, yet non‐unique source inference limits our ability to resolve slip complexity and dynamics. Here we evaluate the effect of spatial smoothing regularization in Bayesian frameworks by comparing an unregularized (BUR) approach that samples distributed ...

Submarine Flank Collapses at Tagoro Volcano: Insights From Bathymetric Surveys and 3D Multiphase Simulations

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.

The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Impact‐generated crater rays are well‐documented on the Moon, with most appearing as high‐albedo streaks extending radially from a crater's center. On Mars, however, crater rays are significantly rarer and discernible only through thermal imaging due to their lower thermal inertia compared to surrounding terrain.

Subsurface Structure and Morphometry of the Wrinkle Ridges in the Late Amazonian Volcanic Unit on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Wrinkle ridges are widespread compressional tectonic features on Mars and are important records of the planet's global contractional history. However, their formation, evolution and subsequent modification by other geologic processes remain poorly constrained.

The Role of Magmatic Styles in Planetary Thermal Evolution Models

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Previous studies that investigated the effects of magmatism on the interior dynamics, in particular for Earth‐sized planets, suggest that magmatism leads to more efficient mantle cooling. However, the extent to which different magmatic styles influence the thermal evolution of planets, and in particular smaller rocky bodies, has not yet been ...

YOLO‐Based Detection and Localization of Rocket Induced Traveling Ionospheric Disturbances

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract During rocket launches, atmospheric disturbances significantly impact the ionosphere, generating Traveling Ionospheric Disturbances (TIDs). These disturbances can affect radio communications and navigation systems and may pose risks to high‐speed aerospace vehicles.

iS‐GNN: Interpolation of Crustal Stress Maps Using a Graph Neural Network Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Estimating the orientation of the maximum horizontal stress (SHmax) from sparse and unevenly distributed geophysical observations remains a persistent challenge in tectonic and geomechanical stress studies. Classical interpolation methods often neglect the multiscale tectonic–geological heterogeneity of the crust, leading to biased estimates ...

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...
