June 27th Lava Flow Observations: The June 27th lava flow remains active. An HVO overflight yesterday morning observed renewed surface breakouts at the flow front, with advancement of the flow tip a short distance north of the ground crack from which it has issued (see “map” link above for updated map). The flow front continues to advance through thick forest, creating smoke plumes. Steaming also continued in cracks around the flow front, suggesting that lava continues to move beneath the surface. The front of the active flows yesterday morning was 13.2 km (8.2 miles) from the vent and 1.4 km (0.9 miles) from the eastern boundary of the Wao Kele o Puna forest reserve.
Small breakouts also remain active closer to Pu?u ????, roughly midway along the length of the June 27th flow. None of these breakouts have been very vigorous recently, and there was no significant change overnight based on webcam views. Some of these breakouts are also creeping into the forest and producing smoke plumes.
