A USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on KÄ«lauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by KÄ«lauea, including sulfur dioxide and carbon dioxide.

Volcano Watch: Low sulfur emissions mean a new focus on a different volcanic gas

Hydrogen sulfide (H2S) smells are still sometimes detected around the island, but it’s another gas emitted by Kīlauea that has become more important lately—carbon dioxide (CO2).
