Kīlauea summit gas team fieldwork – October 22, 2022
HVO volcanic gas specialists make sulfur dioxide (SO~2~) emission rate measurements downwind of the eruption within Halema‘uma‘u crater, Kīlauea summit. This video shows the typical fieldwork involved with measuring SO2 emission rates, during which HVO scientists drive traverses beneath the plume in the closed area of Hawai‘i Volcanoes National Park. As they drive, an ultraviolet spectrometer looks up at the plume to make the measurements. Access to the hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park. Wind noise is audible in many clips.
