The Kahauale‘a 2 flow continues to slowly move through the forest northeast of Pu‘u ‘Ō‘ō. Today, the active flow front was 6.3 km (3.9 miles) northeast of the vent on Pu‘u ‘Ō‘ō. Pu‘u ‘Ō‘ō is just left of the center of the photograph in the distance, partially obscured by the smoke.
A closer view of the active flows at the forest boundary, and the numerous plumes of smoke resulting from active lava igniting ‘oKAHAKOhi‘a trees and other vegetation.
This thermal image, taken from the helicopter on today's overflight, shows the area of active pāhoehoe near the flow front of the Kahauale‘a 2 flow, northeast of Pu‘u ‘Ō‘ō. Blue and purple areas show warm but inactive areas of the flow, while the white and yellow areas are actively flowing lava. The flow surface consists of numerous scattered pāhoehoe lobes, and the advancement of the flow as a whole results from the combined, incremental movement of these individual lobes. The black (cold) area at the top of the image is forest.
The summit lava lake is contained within the Overlook crater, which is about 160 m (520 ft) by 210 m (690 ft) in size, and set within the larger Halema‘uma‘u Crater. The lava lake this week has been about 50 m (160 ft) below the rim of the Overlook crater.
