Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds. The yellow outline is the flow margin as mapped on Monday, December 22.

The image above shows a close-up of the June 27th lava flow in the area of Kaohe Homesteads and Pāhoa. Although the leading tip of the flow stalled earlier this week, active breakouts have persisted a short distance upslope of this stalled front. The image shows active breakouts (red pixels) roughly 150 meters (160 yards) upslope of the stalled tip, with additional breakouts scattered upslope.

The image above shows the extent of the entire June 27th lava flow, from its vent on Puʻu ʻŌʻō to the flow front near Pāhoa, and provides an overview of the distribution of active breakouts on the flow. Near the vent, an area of active breakouts is present about 3 km (2 miles) northeast of Puʻu ʻŌʻō. Farther downslope, breakouts are active in the area of ground cracks. Closer to the flow front, breakouts are scattered just uplslope of the stalled tip of the flow.
