Thursday, April 20, 6:00 am – Pu‘u ‘O‘o & Kalapana overflight:
Eruptive activity persists on Kilauea’s east rift zone, as Pu‘u ‘O‘o continues to feed flow 61G. Light winds from the southwest made for extremely voggy skies over east Hawaii, but it also gave us the opportunity to view the vent’s lava pond from a different angle today. Vigorous spattering occurred from two spots along the southwest wall of the collapse pit, and gases rose high to the northeast, allowing us to look virtually straight down onto the activity. Meanwhile, the March 5th flow is advancing toward Pulama Pali, just reaching the point where one of the previous breakouts occurred, roughly 1/2 mile above the crest of the steep hill. The flow is spread out over a wide area, so its progress has been slow… but consistent. The Kamokuna ocean entry remains active, and the delta has extended a little further seaward. Stress fractures indicate that the new lava bench is under stress, and hazards of being in the general vicinity remain extreme.
