Detailed Description
A comparison of a thermal image (left) with a normal photograph (right) of the Kahauale‘a 2 flow front. Brighter colors in the thermal image depict hotter surface temperatures, with white and yellow areas showing active pāhoehoe breakouts. These breakouts are distributed in a scattered fashion across this portion of the flow field. The vent for the Kahauale‘a 2 flow is on Pu‘u ‘Ō‘ō, visible in the upper left of the photograph.
