Active breakouts persist upslope of stalled flow tip
The leading tip of the flow near Pahoa Marketplace remains stalled, but active breakouts persist a short distance upslope. Breakouts were active about 500 meters (0.3 miles) upslope of the stalled tip, and a portion of this activity on the north margin triggered a small brush fire.
This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the stalled flow tip. In the thermal image, active breakouts are visible as white and yellow areas. About 700 meters (0.4 miles) upslope of the stalled tip, a small lobe is expanding towards the north-northeast, and had triggered a small brush fire this morning. Breakouts were also active farther upslope, with another north-northeast advancing lobe about 2 km (1.2 miles) upslope of the stalled tip.
A closer look at the leading edge of the north-northeast advancing lobe that was active about 2 km (1.2 miles) upslope of the stalled flow tip. This lobe has crossed a fire break, and a small brush fire was active along the flow margin.
A view of the leading edge of the flow, looking downslope towards Pahoa Marketplace and Highway 130. The brush fire was triggered along the edge of a small north-northeast advancing lobe that was active about 700 meters (0.4 miles) upslope of the stalled flow tip.
This close-up view of an inactive portion of the flow margin shows the irregular surface relief created from pāhoehoe flow inflation.
Winds from the south provided a fairly clear view in Pu‘u ‘Ō‘ō crater. At the right side of the photograph, a thick fume source is situated on the northeast rim of the crater.
