Thermal Image of Halema'uma'u
Detailed Description
This image was collected from a thermal camera at the Halema`uma`u Overlook, and shows the current activity at the summit. The active lava pond, about 40 m across, is situated deep within the vent cavity, at a depth of about 200 m. The lava surface consists of slowly migrating crustal plates, with a spattering source on the east margin of the pond. The lava surface is slightly deeper than its usual level, owing to deflation during the current deflation-inflation (DI) cycle.
