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.

Surface flows remain active on the pali and coastal plain, but have not made significant progress towards the ocean. On today's field visit, the closest flows to the ocean were about 2 km (1.2 miles) from the water. This image shows a pāhoehoe breakout at the flow front, with a rigid ropy section of crust being carried forward by the flowing lava beneath it.
