Sulfur dioxide and hydrogen sulfide gases themselves are not visible, but dramatic plumes are sometimes visible at Kilauea Volcano’s summit (shown here) and Puʻu ʻŌʻō. These plumes are a result of atmospheric conditions rather than increased volcanic activity, and frequently occur when warm volcanic gases condense as they are released into cooler air temperatures of early mornings or evenings.
