Collecting gas samples at Sulphur Banks
Detailed Description
HVO gas geochemists periodically collect gas samples at Sulphur Banks, near the Kīlauea Visitor Center, in Hawai‘i Volcanoes National Park. Samples are analyzed for bulk chemistry and for helium isotopes. The results are compared to previous measurements to evaluate potential changes in activity at the volcano. In this image, two HVO geologists collect volcanic gas in a specialized glass bottle. USGS image by P. Nadeau.
