It's not just volcanoes in Hawaii that bear watching. Mount Spurr, in Alaska has also been restless this year. Check out this overflight video by the Alaska Volcano Observatory during gas emissions measurements on December 18. (No changes in emission rates compared to June). Mount #Spurr update: On Dec 18, an AVO crew conducted a gas and observation flight to measure volcanic gases (H2O, SO2, CO2, H2S) and do a photo survey of the summit and Crater Peak. Enjoy this video taken during the flight!
