The Santorini 2024–2025 Volcano‐Tectonic Sequence: Constraining the Initial Phase of the Intra‐Caldera Unrest

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract After less than 14 years from the previous 2011–2012 unrest, the Santorini volcano entered a new unrest phase, involving intra‐caldera deformation since July 2024 and microseismicity mainly after mid‐September 2024. We examine the first phase of this unrest, identified by GNSS and Synthetic Aperture Radar Interferometry data as an almost ...

Unveiling Ionospheric Response to the May 2024 Superstorm With Low‐Earth‐Orbit Satellite Observations

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

New Insights on the Crustal Deformation in the Eastern Betics From Densified GNSS Data

open access: yesTectonics, Volume 44, Issue 2, February 2025.
Abstract The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within the region, the Eastern Betic Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in

Identification of the spatial position of permanent GPS stations in the Baltic region

open access: yesAviation, 2012
Since the last decade of the 20th century, data on repeated measurements from the Global Positioning System (hereinafter referred to as GPS) have been commonly used globally to investigate the motion of the Earth's crust. With the use of data on repeated

Ionospheric Response to the 24–27 February 2023 Solar Flare and Geomagnetic Storms Over the European Region Using a Machine Learning–Based Tomographic Technique

open access: yesSpace Weather, Volume 23, Issue 1, January 2025.
Abstract Two solar flares accompanied by coronal mass ejections (CMEs) occurred on 24–25 February (DOY 055–056), 2023, resulting in a large magnetic storm on DOY 058. We reconstructed the ionospheric electron density (IED) in Europe to analyze the spatial distribution of ionosphere and its temporal evolution during this period. Computerized ionospheric

Carbon border adjustments or climate clubs: Impacts on African agricultural sectors under different cooperative scenarios

open access: yesThe World Economy, Volume 48, Issue 1, Page 119-152, January 2025.
Abstract Despite the rapid acceleration of climate change, international climate negotiations have yet to implement effective mitigation action. This failure can be attributed to the phenomenon of free‐riding behaviours and the adverse effects of unilateral abatement policies, such as carbon leakage.

Ionospheric TEC Forecast Using Bi‐LSTM With the Adam Optimizer During X‐Class Solar Flares Occurred in the Year 2024 and Validation With IRI‐2020

open access: yesAdvances in Astronomy, Volume 2025, Issue 1, 2025.
Satellite communication and navigation systems have become more essential to everyday life, but at the same time, understanding the effect of solar activity on these systems is vital. Total electron content (TEC) is a key factor affecting satellite signals.
