Hydrogen and hydrogen sulphide in volcanic gases: abundance, processes, and atmospheric fluxes

Autor: Aiuppa, Alessandro, Moussallam, Yves

Publikováno v: Comptes Rendus. Géoscience, Vol , Iss , Pp 1-23 (2023)

Hydrogen (H$_{2}$) and hydrogen sulphide (H$_{2}$S) are typically present at only minor to trace levels in volcanic gas emissions, and yet they occupy a key role in volcanic degassing research in view of the control they exert on volcanic gas reducin

A novel approach to volcano surveillance using gas geochemistry

Autor: Moussallam, Yves, Oppenheimer, Clive, Scaillet, Bruno

Publikováno v: Comptes Rendus. Géoscience, Vol , Iss , Pp 1-14 (2022)

Identifying precursory phenomena is central to the short-range assessment and anticipation of volcanic hazards. The chemistry of gases, which may separate from magma at depth, is operationally monitored at many volcanoes worldwide to manage risk. How

Numerical simulations of the latest caldera-forming eruption of Okmok volcano, Alaska

Autor: Burgisser, Alain, Peccia, Ally, Plank, Terry, Moussallam, Yves

Publikováno v: Alaska, Bulletin of Volcanology 86:77 (2024)

The 2050 14C yBP caldera-forming eruption of Okmok volcano, Alaska, had a global atmospheric impact. The associated global climate cooling was driven by the amount of sulfur injected into the stratosphere during the climactic phase of the eruption. T
