What is volcanic gas?
VolcanoesVolcanic gases
Quick Answer
Volcanic gas is gas released from magma or erupting vents, mainly water vapor, carbon dioxide, and sulfur gases.
The Full Story
Volcanic gases are dissolved in magma and escape as pressure drops during ascent and eruption. Water vapor is usually the largest component, but carbon dioxide, sulfur dioxide, hydrogen sulfide, and other gases can also be important. These gases can be toxic, can acidify rain, and can contribute to air-quality problems and climate effects. Gas emissions are closely monitored because changes can signal rising magma.
