A USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on Kīlauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by Kīlauea, including sulfur dioxide and carbon dioxide. USGS photo by Patricia Nadeau.The USGS Hawaiian Volcano Observatory is exploring the use of Unmanned Aerial System (UAS) flights as a means of measuring the ratio of carbon dioxide to sulfur dioxide gases emitted by Kīlauea. The importance of this ratio and what it can reveal about magma within Kīlauea is the topic of HVO's Feb. 21, 2019, "Volcano Watch" article, Low sulfur emissions mean a new focus on a different volcanic gas.
