Kahauale‘a 2 flow still active in forest northeast of Pu‘u ‘Ō‘ō.
Kahauale‘a 2 flow still active in forest northeast of Pu‘u ‘Ō‘ō
The Kahauale‘a 2 flow remains active, and continues to slowly expand into the forest northeast of Pu‘u ‘Ō‘ō. The photo shows the main area of vegetation fires, along the north margin of the flow. Mauna Loa can be seen in the distance in the upper right.
The flow front of the Kahauale‘a 2 flow has cut a narrow swath through forest northeast of Pu‘u ‘Ō‘ō. The narrow lobe at the front is now inactive, with the main area of surface flows about 2km (1.2 miles) behind the end of this lobe. Some of these surface flows are slowly expanding northward into the forest, creating vegetation fires. Pu‘u ‘Ō‘ō is in the upper left. An equivalent thermal image is shown to the right.
This thermal image shows the front of the Kahauale‘a 2 flow. A narrow lobe at the very front is now inactive (evident by the slightly lower surface temperatures), while the main area of active surface flows (shown by white areas) are farther back from this leading edge.
This photo looks southwest, and shows Pu‘u ‘Ō‘ō. The northeast spatter cone on the east rim of the crater is near the center of the photo, and is the vent area for the Kahauale‘a 2 flow. The lava tube feeding the Kahauale‘a 2 flow extends from the northeast spatter cone down the north flank of Pu‘u ‘Ō‘ō, in a direct line towards the lower right corner of the photo. The thermal image on the right is an equivalent view, and highlights the lava tube well.
This thermal image shows Pu‘u ‘Ō‘ō (see visual photograph at left for equivalent view). Recently, the southeast and northeast spatter cones have produced small overflows out of the crater, shown clearly here by their warm temperatures. The vent for the Kahauale‘a 2 flow is at the northeast spatter cone, and the lava tube supplying the Kahauale‘a 2 flow is obvious as the line of elevated temperatures extending to the lower right corner of the image.
It was remarkably clear during today's overflight of Kīlauea's east rift zone. This photo is taken from Pu‘u ‘Ō‘ō, and looks northwest. Mauna Kea is at the right, and Mauna Loa is at the left. In front of the summit of Mauna Loa, the degassing plume from the lava lake at Kīlauea's summit is rising vertically.
