The KahaualeÊ»a 2 flow remains active Wednesday (Nov 27), and continues to slowly expand into the forest northeast of PuÊ»u ʻŌʻÅ. 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. Photo courtesy of USGS/HVO
The flow front of the KahaualeÊ»a 2 flow has cut a narrow swath through forest northeast of PuÊ»u ʻŌʻÅ. 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. PuÊ»u ʻŌʻŠis in the upper left. Photo courtesy of USGS/HVO
This thermal image shows the front of the Kahaualeʻa 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. Photo courtesy of USGS/HVO
This photo looks southwest, and shows PuÊ»u ʻŌʻÅ. 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 KahaualeÊ»a 2 flow. The lava tube feeding the KahaualeÊ»a 2 flow extends from the northeast spatter cone down the north flank of PuÊ»u ʻŌʻÅ, 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. Photo courtesy of USGS/HVO
It was remarkably clear during Wednesday’s (Nov 27) overflight of KÄ«lauea’s east rift zone. This photo is taken from PuÊ»u ʻŌʻÅ, 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 KÄ«lauea’s summit is rising vertically.

This thermal image shows PuÊ»u ʻŌʻÅ. 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 KahaualeÊ»a 2 flow is at the northeast spatter cone, and the lava tube supplying the KahaualeÊ»a 2 flow is obvious as the line of elevated temperatures extending to the lower right corner of the image.

A lava lake within the Halema‘uma‘u Overlook vent produced nighttime glow that was visible via HVO’s Webcam during the past week. A deflation-inflation cycle (DI event) occurred on Friday-Saturday (Nov 22-23) and the lava-lake level fluctuated correspondingly.
On KÄ«lauea’s East Rift Zone, the Kahauale‘a 2 flow continues to advance slowly into the forest northeast of Pu‘u ‘Ō‘Å. The flow front that had recently reached 7.3 km (4.5 miles) from Pu‘u ‘Ō‘Šis no longer active. Surface flows remain active, however, about 5 km (3 miles) northeast of Pu`u `O`o.
There was one felt earthquake in the past week on the island of Hawai‘i. On Monday Nov 25, 2013, at 4:37 a.m., HST, a magnitude-2.7 earthquake occurred and was located 7 km (4 mi) southwest of Volcano Village at a depth of 32 km (20 mi).

Map showing the Kahaualeʻa 2 flow in relation to the eastern part of the Big Island as of November 27, 2013. The tip of the Kahaualeʻa 2 flow that reached 7.3 km (4.5 miles) from Puʻu ʻŌʻŠlast week is no longer active. Flows remain active, however, about 5 km (3 miles) northeast of Puʻu ʻŌʻŠwhere they continue to spread into the forest. The area of the area Kahaualeʻa 2 flow as of November 21 is shown in pink, while widening of the flow as of November 27 is shown in red. Older lava flows are distinguished by color: episodes 1–48b flows (1983–1986) are shown in gray; episodes 48c–49 flows (1986–1992) are pale yellow; episodes 50–55 flows (1992–2007) are tan; episodes 58–60 flows (2007–2011) are pale orange, and episode 61 flows (2011–2013) are reddish orange. The active lava tube is shown with a yellow line.
