International audiencePassive volcanic degassing results in the emission of toxic gases such as H 2 S at quasi-steady rates over long periods that pose a significant hazard to human health even in low gas concentrations. Currently, La Soufrière de Guadeloupe has one of the highest gas emission rates in the Lesser Antilles arc, with gas emitted mainly from low-temperature fumaroles. In this study, gas dispersion from the volcano between 2016 and 2021 was modelled using a numerical code that takes into account wind and atmospheric data, topography, and gas flux measurements. We ran c.100 individual simulations of the most frequently observed wind and gas flux conditions using a Monte Carlo scheme. Our results, validated using air-quality meas...
