volcanic gas
Eruption's invisible breath
Volcanic gas refers to gases released from magma during volcanic activity—primarily water vapor, carbon dioxide, and sulfur dioxide, along with smaller amounts of hydrogen sulfide and other compounds.
These emissions escape through vents, fumaroles, and eruptions, and can pose hazards to nearby populations: Volcanic gas killed livestock in the valley.
Monitoring volcanic gas helps scientists predict eruptions.
