This thermal image looks southwest towards the vent on Pu‘u ‘Ō‘ō, and shows much of the Kahauale‘a 2 flow. Hotter colors (yellow and white) represent active breakouts, while warm colors (red and purple) show recently active portions of the flow. The Kahauale‘a 2 flow consists of numerous scattered breakouts of pāhoehoe lava, with a narrow finger of lava forming the flow front. The flow front today was 5.8 km (3.6 miles) northeast of the vent on Pu‘u ‘Ō‘ō.

An HVO geologist shields his face from the intense heat as he takes a sample of active lava on the Kahauale‘a 2 flow. The chemistry of the lava is analyzed through time and used to study changes in the magmatic system.
