Detailed Description
A breakout from the episode 61g vent at the head of the lava tube on November 21 sent lava streaming downslope. That breakout was still active when observed on November 29 and had traveled about 1.3 km (0.8 miles), partly surrounding Pu‘u Halulu, a tephra cone formed in 1983 at the start of the Pu‘u ‘Ō‘ō eruption. The PEcam webcam looks upslope from Pu‘u Halulu toward Pu‘u ‘Ō‘ō, which is shrouded by clouds (top background).
