Lava Update: Thursday, June 23rd, 6:00 am – Pu‘u ‘O‘o overflight

Eruptive activity continues on Kilauea’s east rift zone, with flow 61g continuing its downhill progression. The leading edge was nearing the crest of the Pulama Pali and the upper boundary of Royal Gardens subdivision, and is traveling over terrain with increasing slope. The flow field is very wide, with breakouts occurring throughout, as an efficient tube system has not yet been established. That being said, while the flow continues to straddle the edge of the Peace Day flow, it appears that the lowest grade is over an older flow to the west, and the branch moving over that area is flowing at a quicker rate and narrowing. Meanwhile, up at the vent, the direction of the wind caused the gas plume to blow directly over the crater, obscuring the view of the lava pond. The Cookie Monster looking hornito has lost its head… and the outflow of lava from Pu‘u ‘O‘o is still visible from the large skylight on its northeast rim.

The Cookie Monster has lost its head! lol… The Cookie Monster shaped hornito on Pu‘u ‘O‘o’s northeast flank has crumbled a little, losing its namesake shape.
