Epistemus (Sonora) [online]. 2021, vol.15, n.30, pp.39-45.  Epub 26-Jun-2023. ISSN 2007-8196.  https://doi.org/10.36790/epistemus.v15i30.160.

The study of volcanic gases includes different processes ranging from regional to global scales, and that occur over a long timescale. Volcanic gas emissions contributed to the creation of the first primordial atmosphere and currently contributes to the regulation of surface processes, such as climate, biogeochemical process and chemical properties of surface waters. In the history of the Earth, large emissions of gases perturbed the climate balance and were responsible for massive extensions. Catastrophic eruptions also emit large amounts of reactive gases, causing disturbance in atmospheric chemistry and generating significant and immediate climatic effects. The monitoring of volcanic emissions constitutes an active field in the investigation of gases and their interaction with the atmosphere.
