Changes at Pu‘u ‘Ō‘ō and views of the 61g flow


Today at Kīlauea Volcano's episode 61g Kamokuna lava delta, there was no lava entering the ocean or breakouts on the delta. The tiny tube breakout that started over the weekend, approximately 840 m (0.5 mile) from the emergency road, was weakly active today. Closer to the base of the pali, there were more active surface flows, as well as on and above the pali.
This thermal image shows the lack of active breakouts or lava streams on the Kamokuna lava delta, which has been inactive for several days. Farther upslope, scattered breakouts are active on the coastal plain and pali.
A channelized flow broke out on Pūlama Pali today from the eastern tube (June 26 breakout). This flow quickly advanced down the steep part of the pali.
A telephoto view of the channelized breakout source on Pūlama Pali. While the fluid lava rushes downslope, gas escapes through bubbles at the surface (seen near the breakout point). As the lava cools, it forms a crust which develops over the channel starting along the edges. If the breakout persists, it could completely crust over to form a lava tube.
A view of Pu‘u ‘Ō‘ō Crater looking west, with the main crater in the center of the photo. In the background the west pit can be seen adjacent to the larger crater, which has an active lava pond inside. The northeast spillway vent, lower right, consisted of two smaller vents up until a few weeks ago when a collapse in the highly altered area combined them into a single degassing vent. A lava stream has previously been visible inside, but no lava could be seen on today's overflight.
Telephoto view of one of the spattering sites on the west pit lava pond margin, in Pu‘u ‘Ō‘ō crater. Molten spatter is being thrown in the air, and landing on the thick pond crust. Solidified pieces of spatter around the source on both the pond surface and the ledge above have a mottled appearance.
This video shows the channelized flow that was active on the pali today.
