Halogen activation in the plume of Masaya volcano: field observations and box model investigations
(Atmospheric Chemistry and Physics, 2020)
Volcanic emissions are a source of halogens to the atmosphere. Rapid reactions convert the initially emitted hydrogen halides (HCl, HBr, HI) into reactive species e.g. BrO, Br2, BrCl, ClO, OClO and IO. The activation ...
Understanding and forecasting phreatic eruptions driven by magmatic degassing
(Springer Nature, 2018-05-18)
This paper examines phreatic eruptions which are driven by inputs of magma and magmatic gas. We synthesize data from several significant phreatic systems, including two in Costa Rica (Turrialba and Poás) which are currently ...
Drones Swoop in to Measure Gas Belched from Volcanoes
(EOS. Science News by AGU, 2018-07-25)
Los gases volcánicos son importantes herramientas de pronóstico de erupciones que se utilizan a menudo en el monitoreo de volcanes. Sin embargo, la recolección de muestras de gas requiere que los científicos ingresen a ...
Carbon and sulfur isotopes in tree rings as a proxy for volcanic degassing
(Geological Society of America, 2019-07-05)
Trees are useful archives of past atmospheric conditions. They have most commonly been used to infer large-scale changes in climate, industrial pollution, and the magnitude and frequency of geological hazards. While ...
