Volcanic gases are an important part of eruptions — they help magma to rise within the earth and erupt, they can tell us how much lava is being erupted, and the volcanic air pollution (vog) they cause can be a hazard. So it is important for the USGS Hawaiian Volcano Observatory (HVO) to measure how much of what kind of gas is being emitted by our volcanoes.
