Kahauale‘a 2 flow still moving through forest northeast of Pu‘u ‘Ō‘ō, and a lava pond in Pu‘u ‘Ō‘ō
Mar 7, 2014: The Kahauale‘a 2 flow remains active, and the active flow front is moving through thick forest northeast of Pu‘u ‘Ō‘ō. The flow front today was 7.9 km (4.9 miles) northeast of the vent on Pu‘u ‘Ō‘ō. Pu‘u ‘Ō‘ō is visible in the upper left of the photograph, and is partly obscured by fume.
Mar 7, 2014: View of Pu‘u ‘Ō‘ō from the south. Pu‘u ‘Ō‘ō's tan-colored south flank is composed of cinder and spatter erupted in its early years (mid-1980s). Since that time, the cone has partially collapsed and lava flows have erupted on the flanks and within the crater, sometimes spilling over the crater rim. In the crater, there have recently been several small spatter cones emitting fume. Mauna Kea's snow-covered summit is visible in the distance.
Mar 7, 2014: The northeast spatter cone has had a small (10 meters, or 30 feet, wide) lava pond, which experiences a cyclic rise and fall of the lava surface called "gas pistoning", driven by the buildup and release of gas in the pond. This photograph captured the moment of gas release, which involved vigorous spattering. In the upper left, the plume from Kīlauea's summit lava lake can be seen in front of Mauna Loa, and in the upper right Mauna Kea is visible.

Mar 7, 2014: This thermal image, taken from the helicopter, shows an area of the Kahauale‘a 2 flow near the flow front. This area consists of numerous small, scattered pāhoehoe lobes. Areas which are white and yellow are active, flowing pāhoehoe lava, while red and purple areas are recently active, but still warm, surfaces.
Mar 7, 2014: The lava lake in the Overlook crater, within Halema‘uma‘u Crater, at Kīlauea's summit remains active. Today, winds carried the plume towards the north, providing a clear view of the persistent spattering area in the southeast portion of the lake.(Public domain.)
Mar 7, 2014: This Quicktime movie shows Kīlauea's summit lava lake in Halema‘uma‘u Crater. A persistent spatter source is active on the lake margin.
