Breakouts remain active in three general areas near Pu‘u ‘Ō‘ō: 1) at the northern base of Pu‘u ‘Ō‘ō, 2) just north of Kahauale‘a, and 3) the most distal breakout, about 6 km (4 miles) northeast of Pu‘u ‘Ō‘ō. This photograph shows much of the most distal breakout, a portion of which was burning forest. Pu‘u ‘Ō‘ō can be seen near the top of the photograph.
The breakout north of Kahauale‘a has one lobe that has traveled along the west side of the perched lava channel that was active in late 2007. This breakout consists of blue glassy pāhoehoe, which is easily visible in the photograph on the left. The white box shows the rough extent of the thermal image on the right. Active (flowing) portions of the breakout are shown by yellow and white colors, while the red and purple areas show hot, but solidified, portions of the surface crust.
In the time since our last overflight (March 24), a new collapse pit has formed in the western portion of Pu‘u ‘Ō‘ō Crater. This circular pit can be seen in the lower left portion of the photograph, and measures about 27 m (roughly 90 ft) in diameter. Numerous hot cracks were observed in this general area during previous visits on foot.
A closer look at the new pit in the western portion of Pu‘u ‘Ō‘ō Crater. Views inside the crater with the naked eye were obscured by thick fume, but the thermal images (right) revealed two areas of ponded lava, separated by a pile of collapse rubble, deep within the pit. Measurements using the thermal camera images indicated that the lava pond surface was roughly 24 m (about 80 ft) below the rim of the pit.
