Image Collection | Hazards and Processes | Volcanic Gases

There are 5,901 volcano images available on the GVP website, including 4,165 in these new galleries with updated captions and keywords, and at a larger size.

Magma contains dissolved gas that is released as it moves towards the surface and as it erupts, providing the driving force for most eruptions. Gases include water (H2O), carbon dioxide (CO2), Sulfur Dioxide (SO2), Hydrogen Chloride (HCl), Hydrogen Fluoride (HF), Particulate Matter (PM), and Aerosol. Gases can be corrosive and can have health impacts or result in fatalities. Gas is also released into the atmosphere through soil, vents, fumaroles, and hydrothermal systems. It is rare that enough volcanic gas is erupted to impact climate and this depends on a number of factors including the location of the volcano.
