Active breakouts persist upslope of stalled flow front
Although the leading tip of the flow remains stalled roughly 500 meters (550 yards) upslope of Highway 130, active breakouts persist a short distance upslope of the stalled tip. These active breakouts are evident as small smoke plumes on the flow margin, where lava is burning vegetation.
This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the inactive flow tip. The white box shows the rough extent of the thermal image on the right. In the thermal image, active breakouts are visible as white and yellow areas. Although active breakouts are absent at the inactive tip of the flow, breakouts are present just a short distance behind the tip, and are also scattered further upslope.
This section of the flow, which has cut through forest west of Kaohe Homesteads, is relatively narrow. In the left portion of the photograph, the flow is slightly more than 100 meters (110 yards) wide.
Breakouts were also active in the upper portion of the flow field today. This pāhoehoe lava is flowing over ‘A‘ā erupted from Pu‘u ‘Ō‘ō in the 1980s.
A wider view of the breakout in the upslope portion of the June 27th flow. Active surface lava was about 3.5 km (2.2 miles) northeast of Pu‘u ‘Ō‘ō, which can be seen in the upper left corner of the photograph.
The pāhoehoe breakout northeast of Pu‘u ‘Ō‘ō is seen here covering older (1980s) ‘A‘ā. Many pieces of the old ‘A‘ā clinker were surrounded by the solidifying pāhoehoe, and then lifted by the inflating flow surface.
This view looks west at Pu‘u ‘Ō‘ō. In the lower left portion of the photograph, the circular perched lava pond that was active in early July can be seen. Just to the right of this perched lava pond, a line of white fume can be seen extending to the lower right corner of the image. This fume marks the path of the subsurface lava tube for the June 27th lava flow. The vent for the June 27th flow, and the start of the lava tube, is slightly below the center point of the photograph.
