This thermal image looks northeast from Pu‘u ‘Ō‘ō, and shows how the subsurface lava tubes feeding the active breakouts on the Kahauale‘a 2 flow are clearly visible as lines of slightly higher temperatures on the surface. At the bottom of the image, the lava tube coming from Pu‘u ‘Ō‘ō forks, with the eastern branch supplying lava to the main area of active breakouts (5 km, or about 3 miles, northeast of Pu‘u ‘Ō‘ō) and the western branch feeding a small area of breakouts about 2 km (1.2 miles) north of Pu‘u ‘Ō‘ō.
