Validation of the Lower Tagus Valley velocity and structural model using ambient noise broadband measurements [PDF]

open access: yes, 2012
Along his history the Lower Tagus Valley (LTV) region was shaken by several earthquakes, some of them were produced in large ruptures of offshore structures located southwest of the Portuguese coastline, among these we the Lisbon earthquake of 1 November

Intense Ground Magnetic Perturbations During the 2024 May and October Geomagnetic Storms

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The May and October 2024 geomagnetic storms represent two of the most intense space weather events of Solar Cycle 25. While differing in global intensity, both storms produced extreme ionospheric disturbances, including equatorward auroral expansion to mid‐latitudes and rapid geomagnetic variations (dH/dt $\text{dH}/\text{dt}$).

Quantifying Gas and Thermal Energy Emissions in an Active Geothermal Area: Insights From Le Biancane (Larderello Field, Italy)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Larderello‐Travale area in the northern Apennines of Italy hosts the world's oldest exploited geothermal field. Its success lies primarily in the presence of an extraordinary geothermal resource housed in a large vapor‐dominated fractured reservoir that produces superheated steam.

Archeointensity Database and Geomagnetic Field Reference Curves for South America Over the Past 5 Millennia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...
