Breakouts continue northeast of Pu‘u ‘Ō‘ō; November 25 breakout remains active
Scattered breakouts persist northeast of Pu‘u ‘Ō‘ō, and the farthest reach of active breakouts today was 5.9 km (3.7 miles) from the vent on Pu‘u ‘Ō‘ō. A minor change on the flow field occurred last week, with a breakout from the tube on November 25 that created a small flow that remains active today. This November 25 breakout is easily visible as the lighter colored area extending to the bottom of the photo. The breakout point is visible by the thick fume on the north flank of Pu‘u ‘Ō‘ō.
A closer look at the breakout point where lava emerged from the tube on November 25. A few skylights provide views of the lava in the new lava tube that formed over the past week on this flow.
A very close view of the active pāhoehoe toes on the margin of the November 25 breakout. A fresh lava sample was collected from this spot with a rock hammer today. Pu‘u ‘Ō‘ō is in the distance.
All that remains of Pu‘u Kahauale‘a can be seen in this photograph, with only the peaks of the formerly prominent forested cinder cone visible. This cone has been buried by lava from the June 27th flow over the past year. In the upper left a small hornito can be seen.
A fascinating cross section of a hornito was revealed recently, when a partial collapse provided a window into a portion of an abandoned lava tube. The void space behind the geologist was filled with lava at some point, with lava and gas forced through the narrow crack in the center of the photograph. This ejected bits of spatter, which solidified around the opening and built a tall hornito.
A few small vents are active in the southern portion of Pu‘u ‘Ō‘ō crater. These erupted a small flow onto the crater floor recently.
