Detailed Description

Image from a thermal camera located on the rim of Halema‘uma‘u crater above the Overlook vent and looking into the vent after the lava lake nearly drained away completely starting March 5. Volcanic tremor and summit deflation began at about 1:42 p.m. HST on March 5, and was shortly followed by draining of the lava lake. Before the draining, the lava lake was about 75 m (246 ft) below the rim of the vent cavity, and about a day later the lava was about 220 m (722 ft) deep, having retreated to the bottom of the vent cavity.
