Perched Pond Collapse in Halema‘uma‘u, Kīlauea Summit (Mar 7, 2021)

This timelapse sequence shows several hours of activity in the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Between March 5-7 a small lava pond developed near the vent. At approximately 1 pm on March 7, the levee of the pond collapsed, allowing the pond lava to drain into the main lake. Minor changes in the geometry of the western fissure, like this, happen occasionally. The timelapse sequence is looped three times.
