Self‐Potential Signal Associated With Hydrothermal System Disrupted by Extreme Raining Events; The Case Study of Formica Leo, Piton de la Fournaise, La Réunion Island

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The scoria cones called Formica Leo located at the base of the Piton de la Fournaise terminal cone have been chosen for its significant positive Self‐Potential (SP) anomalies associated with hydrothermal uprising fluids to monitor SP signal and study its dynamics in relation with huge and extreme rainfall events.

Highlights from a seismic broadband array on Stromboli Volcano

Geophysical Research Letters, 1994
An array of nine three‐component broadband seismometers was deployed in two different configurations on Stromboli volcano. The analysis of the seismic wavefield related to volcanic explosions revealed some observations which offer a completely new insight into the internal dynamics of a volcano.

Megabeds in the Marsili Basin, Tyrrhenian Sea

Basin Research, Volume 37, Issue 6, November/December 2025.
Widepsread and thick megabeds occur in the Marsili Basin of the Tyrrhenian Sea. Megabeds are linked to volcanic eruptions. The Marsili megabeds are recorded by thick turbidites to complex and heterogeneous deposits. ABSTRACT Megabeds, also known as ‘megaturbidites,’ are exceptionally large submarine sediment deposits likely formed by catastrophic ...

Evaluation of Modeled Carbon Monoxide and Methane Columns in the High Arctic Using TCCON Measurements

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Methane (CH4) and carbon monoxide (CO) are gases with important climate impacts as direct and indirect greenhouse gases, respectively. Methane has a warming potential 28 times that of carbon dioxide on a 100‐year timescale, and carbon monoxide is a precursor to ozone in the troposphere.

Characterizing Spatiotemporal Ground Deformation at Whakaari (White Island) Volcano, New Zealand From 2014 to 2024 Using InSAR Time‐Series Analysis

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract Whakaari (White Island) volcano is the most active volcano in New Zealand with a dynamic hydrothermal system. The volcano has had four eruptive periods since 2014. In this study, our aim is to understand the pre‐and post‐eruption deformation processes occurring at Whakaari using interferometric synthetic aperture radar (InSAR).

RNN‐DAS: A New Deep Learning Approach for Detection and Real‐Time Monitoring of Volcano‐Tectonic Events Using Distributed Acoustic Sensing

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract We present a novel Deep Learning model based on recurrent neural networks (RNNs) with long short‐term memory (LSTM) cells, designed as a real‐time volcano‐seismic signal recognition system for distributed acoustic sensing (DAS) measurements. The model was trained on an extensive database of volcano‐tectonic events derived from the co‐eruptive ...

On the singular values decoupling in the Singular Spectrum Analysis of volcanic tremor at Stromboli [PDF]

Natural Hazards and Earth System Sciences, 2006
The well known strombolian activity at Stromboli volcano is occasionally interrupted by rarer episodes of paroxysmal activity which can lead to considerable hazard for Stromboli inhabitants and tourists. On 5 April 2003 a powerful explosion, which can be

Decadal Monitoring of the Hydrothermal System of Stromboli Volcano, Italy

Geochemistry, Geophysics, Geosystems, 2023
In active volcanoes, magmatic fluids rising toward the surface may interact with shallow waters, thereby forming hydrothermal systems that record variations in magma dynamics at depth.

Array tracking of infrasonic sources at Stromboli volcano

Geophysical Research Letters, 2002
Infrasonic arrays are a powerful tool for volcanic monitoring and hazard assessment. Explosions were recorded at Stromboli using a small aperture array of 4 infrasonic stations, allowing precise vent location. The acoustic signals were delayed‐and‐summed, revealing the existence of two main groups of infrasonic waves.
