Kahaualeʻa 2 flow slowly moving through forest northeast of Puʻu ʻŌʻō

The Kahaualeʻa 2 flow continues to slowly move through the forest northeast of Puʻu ʻŌʻō. Yesterday, the active flow front was 6.3 km (3.9 miles) northeast of the vent on Puʻu ʻŌʻō.

This thermal image, taken from the helicopter on today’s overflight, shows the area of active pāhoehoe near the flow front of the Kahaualeʻa 2 flow, northeast of Puʻu ʻŌʻō. 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.
