Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

Advanced Science, Volume 13, Issue 5, 27 January 2026.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...

Breathing and Coughing: The Extraordinarily High Degassing of Popocatépetl Volcano Investigated With an SO2 Camera

Frontiers in Earth Science, 2018
How do lava domes release volcanic gases? Studying this problem is crucial to understand, and potentially anticipate, the generation of the sudden and dangerous explosive eruptions that frequently accompany dome extrusions.

Surface ocean iron fertilization: the role of subduction zone and hotspot volcanic ash and fluxes into the Pacific Ocean [PDF]

, 2011
Surface ocean iron (Fe) fertilization can affect the marine primary productivity (MPP), thereby impacting on CO2 exchanges at the atmosphere-ocean interface and eventually on climate.

Fluid‐Induced Fault Reactivations in Strike‐Slip Regimes: Temporal Constraints From GNSS and Seismological Analysis in the Peloritani Mts and Aeolian Archipelago (Central Mediterranean)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Fluids can modify the mechanical properties of rocks, including shear strength and strain behavior. We investigate the timing and magnitude of seismic events during fault motion in strike–slip systems across the Peloritani Mountains (northeastern Sicily) and Aeolian Archipelago using GNSS and seismological data analysis.

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.
