Yellowstone National Park, which straddles Wyoming, Montana and Idaho, sits on a supervolcano and caldera. For the last 70,000 years it’s been relatively quiet, limited to geysers, hot springs and ground swelling, amongst other types of geothermal activity.
SKYGLOW, an ongoing project exploring the effects and dangers of urban light pollution in the dark areas of the North American sky, recently shot a timelapse of Yellowstone. In a video titled Hades Exhales, the geothermal activity, occasionally accented by colored lights, gets paired with both the clear and nighttime skies. While it pales in comparison to actually being there, the timelapse does show the sheer scope and grandeur, not to mention the danger, of a supervolcano gearing up for the next blast.
As with SKYGLOW’s previous videos, producers Harun Mehmedinovic and Emina Becirovic made Hades Exhales in collaboration with the International Dark-Sky Association, a non-profit fighting to preserve night skies around the globe.
