Volatile emissions from past eruptions at La Soufrière de Guadeloupe (Lesser Antilles): insights into degassing processes and atmospheric impacts

Autor: Abigail Metcalfe, Séverine Moune, Roberto Moretti, Jean-Christophe Komorowski, Thomas J. Aubry

Publikováno v: Frontiers in Earth Science, Vol 11 (2023)

Volatiles exert a critical control on volcanic eruption style and in turn impact the near source environment and global climate. La Soufrière de Guadeloupe in the Lesser Antilles has been experiencing volcanic unrest since 1992, increasing to a peak

Gas Monitoring of Volcanic-Hydrothermal Plumes in a Tropical Environment: The Case of La Soufrière de Guadeloupe Unrest Volcano (Lesser Antilles)

Autor: Severine Moune, Roberto Moretti, Arnand Burtin, David Edward Jessop, Tristan Didier, Vincent Robert, Magali Bonifacie, Giancarlo Tamburello, J-Christophe. Komorowski, Patrick Allard, Margaux Buscetti

Publikováno v: Frontiers in Earth Science, Vol 10 (2022)

Fumarolic gas survey of dormant volcanoes in hydrothermal activity is crucial to detect compositional and mass flux changes in gas emissions that are potential precursors of violent phreatic or even magmatic eruptions. Here we report on new data for

Numerical modeling of the geothermal hydrology of the Volcanic Island of Basse-Terre, Guadeloupe

Autor: Margaux Raguenel, Thomas Driesner, François Bonneau

Publikováno v: Geothermal Energy, Vol 7, Iss 1, Pp 1-16 (2019)

Abstract This study investigates the thermo-hydraulic implications of three geologic scenarios for characterizing the geothermal hydrology of Basse-Terre Island, Guadeloupe. Despite newly acquired magnetotelluric, petrophysical, and geologic data, fl

Journal of Volcanology and Geothermal Research, 2023, 435, pp.107775. ⟨10.1016/j.jvolgeores.2023.107775⟩

International audience; The thermal properties of volcanic materials are required for modelling and for understanding volcanic surface heat fluxes and timescales for cooling magma. However, compared to volcanic rocks, there are relatively few thermal

Bottom-up vs top-down drivers of eruption style: Petro-geochemical constraints from the holocene explosive activity at La Soufrière de Guadeloupe

Journal of Volcanology and Geothermal Research.

Signals of volcanic unrest have been used successfully to provide insights into the timing, magnitude, intensity, and style of future eruptions. However, in order to provide context for the subsequent activity, analysis of past eruptions is required.
