Thermal Image of Halema'uma'u Vent

This thermal image shows the view of the Halema`uma`u vent from today's overflight. The kidney-shaped lava pond, about 90 meters long, is deep within the vent cavity. The mostly-crusted lava migrates from the north (right in this photo), where it upwells from depth, to the south, where is sinks back into the conduit.
