New breakouts southeast of Pu‘u ‘Ō‘ō, clear views into Pu‘u ‘Ō‘ō crater.
New breakouts southeast of Pu‘u ‘Ō‘ō, clear views into Pu‘u ‘Ō‘ō crater
Surface lava flows on the coastal plain and pali died out over Labor Day weekend with summit deflation, and new breakouts appeared on Sunday, September 2, farther upslope with the resumption of summit inflation. The new breakouts, which are modest in size and vigor, are above the top of the pali, about 4 km (2.5 miles) southeast of Pu‘u ‘Ō‘ō.
This thermal camera view from the helicopter looks upslope (northwest), and shows the two main breakouts that are southeast of Pu‘u ‘Ō‘ō. The western breakout was nearly stalled, and most of the activity was focused at the front of the eastern breakout. Both breakouts consisted of pāhoehoe flows.
A view from the helicopter of the lava pond in the east collapse pit within Pu‘u ‘Ō‘ō crater. The pit enlarged substantially last week as the lava pond dropped during a deflation phase. Though the lava level has risen since that time, it remains deep within the collapse pit.
This thermal camera view from the helicopter shows the current configuration of activity within Pu‘u ‘Ō‘ō crater. The view is towards the east. The east pit has hosted an active, circulating lava pond for several months now. The south pit enlarged to its current size just last Thursday (Aug. 30), and has two pads of active lava within it. The north pit also formed on Thursday, and was rapidly filled with lava which is now cooled. For scale, Pu‘u ‘Ō‘ō crater is about 250 m (820 feet) across (spanning the left to right edges of this image).
