Hawaiian Volcano Observatory scientists measure gas concentrations

Detailed Description

On the rim of Halema‘uma‘u crater, Hawaiian Volcano Observatory scientists measure gas concentrations from the ongoing Kīlauea Volcano summit eruption using a FTIR spectrometer. The sulfur-dioxide (SO2) rich eruption plume also contains water vapor, carbon dioxide, and halogen gases such as HCl and HF. Light-weight pieces of volcanic glass, such as Pele's hair and tears, are also carried downwind in the plume. USGS photo by T. Elias on December 23.
