Seismo‐Acoustic Evidence for Meteoric Water Modulation of Hydrothermal Fluid Discharge

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Deciphering the signal of external processes on active hydrothermal dynamics represents a critical challenge in understanding volcanic unrest. At the Pisciarelli hydrothermal site, located within the densely populated Campi Flegrei caldera (Italy), we investigate the role of meteoric water influx in modulating shallow hydrothermal fluid ...

Volcán de Colima

open access: yesGeofísica Internacional, 1993
Volcán Colima is currently one of the most dangerous volcanoes in Mexico. It presents hazards at various scales. It has a history of frequent eruptions during the past 450 years, for which there are written records. To better understand the nature of the

The Gulf of Cádiz: thrusting or strike-slip motion? [PDF]

open access: yes, 2010
In the Gulf of Cádiz (SW Iberian Peninsula) the boundary between Eurasia and Nubia plates corresponds to a narrow band well defined by the seismicity, where large earthquakes (M>7.0) may be associated to N-S to NNW-SSE horizontal compression due to the ...

Modeling the Deformation Response to Mt. Etna Sliding Flank

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The southeastern flank of Mt. Etna volcano slides into the Ionian Sea at rates of centimeters per year. While gravitational spreading and tectonic forces can cause volcanic flank collapse, their effects intrinsically trade off with magmatic forcing. There is still strong uncertainty regarding the processes underlying the sliding.

Seismicity along the western part of the Eurasia-Nubian plate boundary [PDF]

open access: yes, 2012
The seismicity along the western part of the Eurasia-Nubian plate boundary is characterized by a very complex pattern. In average, the motion is transtensional in the Azores, dextral along the Gloria transform zone and convergent between the SW ...

Phytoplankton Bloom Changes During Three Regime Shifts Derived From Sea Ice Concentration in the Ross Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Sea Ice Concentration (SIC) plays an important role in the Antarctic polynyas, especially where biological interactions through changes in chlorophyll‐a concentration (CHL) phenology are concerned. To specifically understand how much SIC change affects CHL in the Ross Sea polynya (RSP), the regime shift index (RSI) was applied to the SIC ...

Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling
