Detailed Description

This movie shows a draining event in the lava pond within the Halema'uma'u vent cavity. The lava column exhibited cycles of filling and draining of the vent cavity, with each cycle lasting a few minutes. As the pond drains, lava cascades into a small hole on the east side (right) of the cavity floor. Also, lava that was covering a large bench to the west of the main pond drains back, with large plates of crust sliding over the edge.
