Abstract:Quantifying subsurface fluid flows and related heat and gas fluxes can provide essential clues for interpreting the evolution of volcanic unrest in volcanoes with active hydrothermal systems. To better constrain the distribution of current hydrothermal activity, we mapped diffuse soil CO2 degassing, ground temperature and self-potential covering the summit of La Soufrière de Guadeloupe during 2022-23. From these mappings, we identify areas of fluid recharge and the zones and extent of major ascending hydrother… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
