  1. Volcanic gases are gases given off by active or dormant volcanoes1. The most abundant volcanic gas is water vapor, which is harmless234. Other gases that can be emitted from volcanoes include carbon dioxide, sulfur dioxide, hydrogen sulfide, and hydrogen halides2. These gases can be hazardous to people, animals, agriculture, and property, depending on their concentrations2. Atmospheric reactions with volcanic gases can rapidly produce substances such as sulphuric acid that act as aerosols, cooling the atmosphere5.

    Volcanic gases are gases given off by active (or, at times, by dormant) volcanoes. These include gases trapped in cavities (vesicles) in volcanic rocks, dissolved or dissociated gases in magma and lava, or gases emanating from lava, from volcanic craters or vents. Volcanic gases can also be emitted through groundwater heated by volcanic action.

    By far the most abundant volcanic gas is water vapor, which is harmless. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes. Depending on their concentrations, these gases are all potentially hazardous to people, animals, agriculture, and property.

    Active volcanoes can emit different types of gases such as such as water vapor (H2O), sulfur dioxide (SO2), carbon dioxide (CO2), hydrogen sulfide (H2S), and others. While water vapor is typically the most abundant gas emitted, scientists keep a close eye on the amount of sulfur dioxide (SO2) emitted because of its association with the magma.

    Ninety-nine percent of the gas molecules emitted during a volcanic eruption are water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2). The remaining one percent is comprised of small amounts of hydrogen sulfide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species.

    What gases are emitted during a volcanic eruption?
    Ninety-nine percent of the gas molecules emitted during a volcanic eruption are water vapor (H 2 O), carbon dioxide (CO 2 ), and sulfur dioxide (SO 2 ). The remaining one percent is comprised of small amounts of hydrogen sulfide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species.

    What gases do volcanoes emit from space?
    A number of volcanoes around the world continuously exhale water vapor laced with heavy metals, carbon dioxide, hydrogen sulfide and sulfur dioxide, among many other gases. Of these, sulfur dioxide is the easiest to detect from space. Volcanic sulfur dioxide emissions from Indonesia’s many volcanoes are shown in shades of orange.

    What is a volcanic gas hazard?
    Volcanic gas emissions are composed mainly of water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2) gas, with trace amounts of several other gaseous compounds, including hydrogen sulfide (H2S), hydrogen fluoride (HF), and carbon monoxide (CO). The chief gas hazard in Hawai‘i results from SO2 gas.
