Time-lapse sequence shows Halema‘uma‘u gas plume

This time-lapse sequence shows the outgassing plume from the Halema‘uma‘u lava lake at the summit of Kīlauea. The images were captured by a camera on the flank of Mauna Loa on May 19, 2017. As the plume rose from the vent, it reached the atmospheric inversion layer, which effectively capped the height of the plume.
