Delineation and Fine‐Scale Structure of Fault Zones Activated During the 2014–2024 Unrest at the Campi Flegrei Caldera (Southern Italy) From High‐Precision Earthquake Locations

Geophysical Research Letters
In the past two decades, the central portion of Campi Flegrei caldera has experienced ground uplift up to 15 mm/month, with an increase of rate, magnitude and extent of the seismicity. In this work, we perform multi‐scale precise earthquake relocation of

Can Domain‐Informed Design Improve Neural Spatio‐Temporal Point Processes for Earthquake Forecasting?

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

Pressurization of Shallow Magma Reservoir Preceding Basaltic Eruptions at an Open‐Vent Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Open‐vent volcanoes are characterized by the persistent activity of outgassing, lava effusion and mild explosions, which is, however, occasionally interrupted by more violent explosive activity (paroxysm), for example, Stromboli (Italy). In spite of the different (two orders of magnitude) explosive intensities and different petrological magma ...

Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.

Volcanism and Seismicity in the Iwo-jima Volcanoes

Journal of Geography (Chigaku Zasshi), 1985
Since the first recorded phreatic explosion occurred in 1889, eruptions took place fifteen times in Iwo-jima. Recently, Iwo-jima volcanoes has been studied from geophysical standpoint including seismometrical, geodetic and geothermal investigations. Most of phreatic explosions has been accompanied with high active stage of shallow earthquakes.

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 1–Model Development

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.

2005–2024 Time–Space Features of VT Seismicity at Stromboli: New Insights into the Volcano Plumbing System and Link to Effusive Eruptions

Applied Sciences
Volcano-tectonic seismic events (VT) are quite rare at Stromboli, numbering about ten events per year and generally with low magnitude. Using a dataset of 98 events from the 2005–2024 period, we report an improved relocation of VT events here.

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

Thermochemical Controls on the X, 410, and 660 Discontinuities in the Central Mediterranean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The mantle beneath the Central Mediterranean is thermally and compositionally heterogeneous, as indicated by fragmented and locally stagnant slabs in tomographic images and HIMU‐like anorogenic magmatism. Mantle discontinuities are sensitive to both temperature and composition, and thus provide a way to quantify these heterogeneities.

Multi‐Scale Spatial Variations in Pacific Mantle Seismic Anisotropy: Constraints on Plate Evolution and Asthenospheric Flow

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...
