A new accurate retrieval algorithm of bromine monoxide columns inside minor volcanic plumes from Sentinel-5P TROPOMI observations [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
Bromine monoxide (BrO) is a key radical in the atmosphere, influencing the chemical state of the atmosphere, most notably the abundance of ozone (O3). O3 depletion caused by the release of bromine has been observed and modeled in polar regions, salt pans,

The Evolution of Peteroa Volcano (Chile–Argentina) Crater Lakes Between 1984 and 2020 Based on Landsat and Planet Labs Imagery Analysis

open access: yesFrontiers in Earth Science, 2021
One of the major challenges in the understanding of the crater lakes dynamics and their connection with magmatic/hydrothermal processes is the continuous tracking of the physical behavior of lakes, especially in cases of remote and poorly accessible ...

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Eleven‐Year Survey of the Magmatic‐Hydrothermal Fluids From Peteroa Volcano: Identifying Precursory Signals of the 2018–2019 Eruption

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Over the past decade, we have conducted geochemical and isotopic monitoring of the fumarolic gases of the Peteroa volcano (Argentina‐Chile). Using the resulting data set, we constructed a conceptual model that describes the evolution of the magmatic ...

First In-Situ Measurements of Plume Chemistry at Mount Garet Volcano, Island of Gaua (Vanuatu)

open access: yesApplied Sciences, 2020
Recent volcanic gas compilations have urged the need to expand in-situ plume measurements to poorly studied, remote volcanic regions. Despite being recognized as one of the main volcanic epicenters on the planet, the Vanuatu arc remains poorly ...

Changes in SO2 Flux Regime at Mt. Etna Captured by Automatically Processed Ultraviolet Camera Data

open access: yesRemote Sensing, 2019
We used a one-year long SO2 flux record, which was obtained using a novel algorithm for real-time automatic processing of ultraviolet (UV) camera data, to characterize changes in degassing dynamics at the Mt. Etna volcano in 2016. These SO2 flux records,

Coupling Between Magmatic Degassing and Volcanic Tremor in Basaltic Volcanism

open access: yesFrontiers in Earth Science, 2018
Magmatic degassing, typically measured as SO2 flux, plays a fundamental role in controlling volcanic eruption style and is one of the key parameters used by volcano observatories to assess volcanic unrest and detect eruption precursors.

Insights Into the Mechanisms of Phreatic Eruptions From Continuous High Frequency Volcanic Gas Monitoring: Rincón de la Vieja Volcano, Costa Rica

open access: yesFrontiers in Earth Science, 2019
Understanding the trigger mechanisms of phreatic eruptions is key to mitigating the effects of these hazardous but poorly forecastable volcanic events.

Patterns of Fine Ash Dispersal Related to Volcanic Activity at West Mata Volcano, NE Lau Basin

open access: yesFrontiers in Marine Science, 2019
Extensive deep (>1500 m) non-hydrothermal ash-rich plumes were present in the water column surrounding West Mata submarine volcano (NE Lau basin) during eruptive phases, but were absent when West Mata was quiescent.

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface
